"If 'I love you' was a promise
Would you break it, if you're honest?"

Elizabeth's POV

It's about nine in the morning and I'm waiting for Y/N to pull up because Will could wake up any second and we need to finish some of the decorations. So far, I've invited the family, Scarlett and Rose, Anthony and his kids, Tom Holland and a few of William's friends who are coming with their parents. Y/N is inviting his mother and a few other people.

My phone makes a sound and It's Y/N saying he's round the corner and won't be long. I'm soon pulled out of my screen when I hear a loud engine crackle. I see Y/N turn up in a Batman costume like he promised me, however it's not the cheap costume I already had for rolepla- The party I mean, He's in the actual suit from the movie. And to top it off he's in the Batmobile, he had to one up me. That mother fucker, well I wish.

Elizabeth: What happened to the costume I gave you?

Y/N: Don't blame me blame the Riddler.

He speaks in his Batman voice, like he's in the role making me grin at how childish he is. I then look over his shoulder to see the car as I remember reading something I found online, I start to grow angry but quickly mask it and continue the conversation, making a mental note for later.

Elizabeth: And the car, let me guess, the Penguins fault?

Y/N: (Laughs) No, that would be a good idea for the sequel though. The car is here because it's fucking awesome.

I grin at him but it's in my amusement, seeing how things like that make him so happy. I shake my head as he shifts his gaze towards me, taking in my outfit.

Y/N's POV

I notice that Lizzie is wearing her costume from the Halloween episode of WandaVision. I remember watching those episodes while I was away filming this year. I'd never imagine myself being sad after it ended, Lizzie is such a good actress.

I swear this outfit is doing something to me and her new hairstyle is making it worse for me to keep it concentrated.

Y/N: I like the, uh... Sokovian fortune teller outfit.

Elizabeth: Thank you.

She does a little twirl around, I could feel my knees getting weak. No! You are Batman Y/N! Concentrate!

She really is a MIL-

-

The two of us make our way to the backyard which is basically with the frontyard. We have to set up a few of the smaller decorations and presents because we did most of the work yesterday. Lizzie is setting up some of the balloons and those banners on a ladder. I finished my bit on the barbecue but I'll start cooking once the guests arrive, nobody wants cold barbecue.

As for guests, I was debating on inviting Andrew and Tobey and his kids but I felt that would be too obvious and No Way Home comes out in a week or so after my Batman press is done. So I can probably take Lizzie to the cinema to watch it with me hopefully after I come back from press. She's always loved my Spider-Man.

But I'm inviting Zoë who's coming with her step dad Jason Momoa who actually plays Aquaman. I'm inviting Shailene Woodley, who played MJ in my Spider-Man movies and Ana De Armas who played Black Cat from my Spider-Man movies. Both are really good friends. I'm also inviting Mom too. I also asked my buddies Ryan Reynolds and Vin Diesel but they said that they'll see, because it's obviously a very busy time and most of these guys are working on projects.

Elizabeth: A little help?! Earth to Y/N!

A took off my cowl to see Elizabeth, on a ladder trying to tie the other end of the banner to the branch. Her ass was literally showing and I couldn't help but have my gaze directed towards that.

Elizabeth: Y/N!

She exclaimed from afar, I got up making my way towards the ladder. She looked down to see me.

Y/N: What.

Elizabeth: Can you tie this end? I'm not tall enough.

Y/N: I'm in a fucking Batman costume, Elizabeth.

Elizabeth: Please?

She innocently asked and I complied, She stepped off the ladder as she went back to help herself to some lemonade with a small smirk evident. That sneaky bitch. I sighed and climbed my way up the ladder, tieing up the end of the banner which said 'Birthday Boy'.

I got down and joined Lizzie by sitting opposite her on the outdoor chairs. I put my cowl back on and lock eyes to bring her attention.

Y/N: Wanna wake up birthday boy?

Elizabeth: Yeah let's do it and I'll get him ready. Guests could be coming in 20 or so minutes.

Y/N: Bet.

-

Entering our sons room, we slowly approach the little boy who is knocked out... Or is he? He seems to forcing his eyes shut with a big grin. I turn to Lizzie with a funny shocked face and we both play along.

Y/N: Oh no! Wills still asleep!

Elizabeth: That's such a shame! Guess we'll have to enjoy all the cake and presents and candy to ourselves!

Y/N: Hmm. He won't even see the Batmobile that's outside!

Elizabeth: I'd hate to miss it!

Suddenly, we're interrupted by William jumping out of his bed and screaming in excitement.

William: I was pretending!

I sweep him up in my arms and ruffle his hair a bit.

Y/N: Happy Birthday William! You're what 102 now?

William: Four!

Y/N: Fourty Four! You should send me that skincare routine.

He chuckles before wiping his hands on my Batman cowl.

William: You wear the good costume but mommy not wear the good costume.

Y/N: I know right, she's wearing something a bit skimpy don't you think?

Elizabeth then shoots me a deathly but playful glare before taking Will in her arms. She showers the boy in kisses making him squeal.

Elizabeth: Happy Birthday my beautiful baby! You're growing up too quick!

I watch in awe, Elizabeth is such a good mother. I hear a few knocks at the door and Lizzie looks back up at me.

Elizabeth: You get the door and I'll get him ready.

Y/N: Alright.

I head downstairs to where the door is, I open it to reveal a family. It was Scarlett and Rose.

Y/N: Scarlett! How are you?

Scarlett: Y/N! OMG it's been like what? Several months. And I'm good!

We hug eachother briefly before I look down to a little girl, holding onto her mother's leg.

Rose: Hewwo Uncle Batman.

The little girl waves and I crouch down to reach the girl I pick her up smiling, letting them in but leaving the door open. I locate her and her daughter to the living room where they sit.

Y/N: Can I getcha anything? Water? Coffee?

Scarlett: I'm fine thanks, Rose and I just had breakfast. Look at you, Batman.

Y/N: Thanks.

Scarlett: You've been pretty busy haven't you lately? You've got Batman coming up and you were in that new Fast and Furious 9 and Spider-Man too?

I laugh out loud shaking my head.

Y/N: I'm not in the Spider-Man movie, those are jusy rumours.

Scarlett: Oh. I read it somewhere. Where's Lizzie and the birthday boy?

Y/N: She's upstairs getting him ready.

Rose: I wanna play with William.

Y/N: Oh they're friends?

Scarlett: Yeah. Rose was just like 'Can we go to Willy's?' For like the past week.

Suddenly, multiple footsteps come to the living room and It's William dressed up as the Batman, his favourite character, It was the only real reason I took the role.

Elizabeth: Scarlett! Hi!

Scarlett: Lizzie!

The two hug and William immediately hides behind my leg, he actually has a little crush on Scarlett so he gets nervous around her sometimes.

Scarlett: William come here! Give me a hug, birthday boy.

She says crouching down with open arms. He jumps into the womans arms and she hugs him tightly before giving him a kiss on the cheek.

Elizabeth: William, why don't you and Rose go play outside.

The two infants storm out the door to play outside as Scarlett gets up on her feet, we also loosely follow outside. As Lizzie and Scar talk I'm taken aback by a strong grip into a bear hug.

Y/N: Oh my God, Vin! You made it!

Vin: Anything for Family.

Y/N: How are you? How's the kids?

Vin: Oh they're here and that's my wife. She's here too.

He says as his family walk out of the car. 2 daughters and his son and wife. I give them a small wave as Vin's son hugs his dad's side.

Vincent (Vin's son): Nice Batman suit. I also saw the Batmobile it's pretty cool.

Vin: Not as cool as your dad's Charger.

Vincent: Dad, it's like a batmobile charger.

Vin ruffles his son's hair making us laugh.

Y/N: Thanks, buddy. I thought the same thing but that's because Bruce Wayne in the movie is an illegal street racer.

Vincent: When's it coming out?

Y/N: Hopefully in a few weeks after No Way Home so you get two awesome hero movies.

Vincent: Are you in that one too?

Y/N: No, but I'll let you in on a little secret.

Vincent: Yeah.

Y/N: Tom Holland is coming to this party, so you can go talk to him.

Vincent: This is probably gonna be the best party ever!

He exclaims excitedly before running back to his mother who's with the other women at the party.

Y/N: Hey. You think you can help me with the Barbecue?

Vin: Lead the way.

Y/N: Sure!

I took my cowl off and gave it to Lizzie on the way, who gave a confused look.

-

3rd Person POV

The party began to grow and Elizabeth's family showed up and Y/N's mother showed up, everyone seemed to get along so far, Elizabeth's parents spending time with their grandson and greeting with Y/N who was with Vin helping make the barbecue.

It was then when a few more people began to make an appearance. A few parents and family friends came along with their kids and everyone had a fun time catching up, Anthony also came along with his chidlren and he situated himself with the three men on the Barbecue.

Elizabeth's POV

I observe from a distance, sitting on a chair as Y/N is cooking up the barbecue, he's also still wearing his suit but he looks mega hot, making me wish I was that suit.

MK: Something catching your eye?

Elizabeth: Oh! Nothing!

Ashley: No, it's definitely something. Y/N's back and you want him, don't you.

I sigh in defeat.

Elizabeth: Yeah. I don't know how to tell him though.

Ashley: Be honest with him.

MK: He deserves to know that you're willing to raise the child together, I mean look at him he's happy surrounded by you and his family, give him that.

Elizabeth: You're right.

Ashley: Yeah, we know. I'm gonna go bully some kids.

I get up and see two more women arriving. It's Shailene and Ana, Y/N must've invited them.

Elizabeth: Shailene! Ana!

Ana: Good Morning Elizabeth!

The three of us hug and they meet up with William, he also knows them because he watches his dad's movies.

William: Hello MJ!

Shailene: Hello William, Happy Birthday!

She picks him up as Ana also greets the boy I look over my shoulder to see Y/N. He has arms open wide and is smiling. Does he want to hug me? Oh yes I'd love that. Before I could go into his arms he instead goes to Ana and Shailene. The three of them hug and he places a few kisses on their foreheads. I'm not mad because I've known them and I know Y/N's relationship with them is strictly platonic.

Y/N's POV

As I pull from the hug I see a few more guests it's Jason and Zoë. I walk over to them and they smile, William also loosely follows me, making sure to not step on my Cape.

Y/N: Hey guys!

Jason: Aloha! Little William!

The man crouches down to Will's level and hands him a small trident as Zoë and I share a tight hug.

Y/N: That is so cool.

Zoë: I know, right. I was telling him not to get it because Will's favourite superhero is Batman.

Jason: You gotta teach em young! How about you ditch the Batman costume and join me in Atlantis?

William: No!

Jason: Ah man! I guess I'll take the trident awa-

William: No its cool, I wike it. Thank yu Uncle Aquaman.

He chuckles at the name and let's him run away to Lizzie. Shailene and Ana approach us and we all greet eachother.

Zoë: Okay, can I take an Instagram selfie?

Y/N: Sure!

Jason stands behind, being the tallest one as Shailene and Ana cuddle up to my sides and Zoë stands infront, taking a selfie with goofy faces.

Zoë: Cheese!

Everyone: Cheeeeese!

After the photo ends everyone gets themselves in the party, taking photos witj people and chattering, I could feel a glare on me as everyone was leaving the spot. It ws Elizabeth. I mouth an 'Are you okay' and her face shifts from a death glare to a small smile giving me a thumbs up. I decide to head inside because my Batman suit getting itchy.

Elizabeth's POV

After seeing Zoë take a photo with my Y/N I can't help but get my jaw clenched, especially after reading what I saw online, I mean it's not Y/N's fault that every girl is getting close to him but I mean dial it down a littl-

Fuck, Y/N is now walking out the house with a white tee on and some jeans, I can see his biceps and damn I just want to my head to be in between his pecs because I can see them and oh my God. He just gets hotter with age.

He is then approached by Tom who has finally arrived the two Spider-Men hug it out and kids begin to approach them, even some adults too.

As they talk, I approach them, I gently tap Y/N's shoulder and he turns to face me he gives a head raise gesturing me to speak.

Elizabeth: How long till the Barbecue's ready?

Y/N then looks over to see Vin who shouts it's ready. Y/N then tells everyone to get ready to eat on the table. Everyone complies and does so. Some people are sitting on the table and some of the kids are playing around or being served with a small plate of meat while they go play. Y/N is so hot when he does things like this, proper DILF behaviour.

Y/N serves every adult and their plate while I look up at him in awe, we all then sit on the table and before we begin eating Vin calls out.

Vin: Let's say grace.

Y/N: Good idea.

Y/N then reaches out for my hand and I gladly take it as everyone hold their hands together, closing their eyes. I could feel Y/N doing small rub on my hand but luckily my makeup is hiding the huge blush on my face. Maybe it's because he's doing it out of instinct, either way I'm not complaining.

Vin: God our times are in your hand; Look with favour as we pray for the celebrant, as William Olsen-L/N begins another year. Grant that he may grow in wisdom and grace, and strengthen his trust in your goodness all the days of his. Amen.

Everyone: Amen.

Y/N: Thank you.

Everyone applauds Vin and Y/N let's go of my hand making me step out of my dream. I also begin to clap.

Elizabeth: Thank you, Vin. That was beautiful.

We begin to dig in our foods in pure enjoyment of the celebration and damn this tastes good, I've missed Y/N's cooking.

Y/N: Wow this is actually good, how is it Lizzie?

Did he call me Lizzie? For the past two days he's been calling me Elizabeth. I've missed him calling me that.

Elizabeth: Huh? Oh yeah this is very good thank you and thank you Vin and Anthony for helping with the Barbecue.

Anthony: You're welcome!

All the adults begin to have small talk and all of us seem to get along, Y/N is telling jokes and we're all talking about adulthood. My parents are also seeming to talk well with Y/N like nothing ever happened between the two of us. I keep my eyes on Y/N's jawline as It flexes when he talks like damn daddy slice me with it.

William then zooms with us and hops onto my lap, I use my free arm as the other is holding my drink to keep him suspended.

William: I bet you can't catch me dad!

Y/N squints his eyes playfully and Will giggles hopping out of my grasp as he leaves his chair and chases his son.

Elizabeth: Beat his ass, Will!

I laugh, watching as MK is now helping Will, the three of them corner Y/N towards the pool then.

Splash.

Y/N is plunged into the pool and my laughter is cut short. Eventually I see him get out of the pool, his white t-shirt is now transparent and sticking to his defined abs and those pecs I wanna park my face in between, I see his H/C hair is slightly damp from getting splashed, oh how I miss running my fingers through it, NO naughty Elizabeth stop. I barely manage to calm myself down and relax and I notice all the gazes of the mothers (some dad's too) staring at him. But when he peels of his wet top and throws it at William in retaliation making everyone laugh I lose it. I'm going mentally feral. I feel my face redden and my legs clamp together. I need to leave. I quickly make my way out of the dining area until I'm stopped.

Y/N: Are you okay, where are you going?

Elizabeth: For a drink.

Y/N: You already have one.

I look down at my practically full cup before I quickly down it in one go.

Elizabeth: No, I need a refill.

I then practically run away, I'm not lying I am thirsty right now for some Y/N but I can get a drink later. I need to calm down and head back out.

Y/N's POV

Okay. Weirdo. I decide to head inside to get some fresh clothes, I'm pretty sure Lizzie should have some in her closet but we'll see. I could practically feel all the mothers daggering gazes on my body.

I walk up stairs and find Lizzie's room, it's a nice large bed but it looks brand new. I find her closet and open it revealing some of her clothes but through some searching I found a box with label that wrote in sharpie 'Y/N <3'. What does that mean? Off topic I have to find some clothes. I find a half sleeve button up and some trousers that Lizzie bought me a long time ago, It smells like her so it obviously smells really good, so I put it on happily after locking the door.

Elizabeth's POV

I come back after gaining some composure now I just have to block out all the dirty thought for the next two hours. I sit back down with Scarlett who was just conversing with Anthony before he had to go help the kids with the pinata.

Scarlett: I'm moving to Gotham.

I see what she's trying to do.

Elizabeth: It will be next to the Wayne's graves.

Scarlett: Nevermind LA is good thanks.

Elizabeth: Good choice.

I reply nonchalantly.

Scarlett: That Bat bod looks good though.

Elizabeth: What did you say?

Scarlett: Nothing.

Elizabeth: Good choice.

Y/N comes back wearing a button up summer shirt, deliberately leaving a few buttons exposed. His hair is still damp which is not helping at all but it's sweet that he dug his clothes out of my closet. Cutey pie. He makes his way over to the table where I'm sat and begins to tell a story to those MOTHERS. DON'T THEY HAVE HUSBANDS? LEAVE MY DREAM MAN ALONE.

I huff and tap Y/N's shoulder making him turn to me with a pursed smile.

Y/N: Yeah, Liz?

Elizabeth: Should we cut the cake?

Y/N: I think we should it's getting late.

-

3rd Person POV

Everyone circled around the table, the adults being behind the table and Y/M/N (Your mothers name) lit the candles of the cake before making her way next to Mama J. Elizabeth was holding onto William as Y/N stood beside, recording the special moment on his phone.

Everyone: Happy birthday to you... Happy birthday to you... Happy birthday dear William... Happy birthday to you!

Elizabeth leaned closer letting William blow out the candles to his cake everyone then applauded happily cheering for a small boy with two celebrity parents.

Y/N smiled kissing the top of his son's head. He cut a slice of cake and fed it into the child's mouth.

Y/N: Lizzie, open wide.

She looked at him for a moment, she wasn't confused but she felt differently towards him than she was years ago. Like nothing happened, she opened her mouth and Y/N slid some cake in her mouth as chuckles and laughs were shared among everybody.

The next moments passed, people were beginning to leave with little party bags. Y/N made sure that Vin and Anthony left with some leftover Barbecue meat as well as anybody else who wanted some, Shailene and Ana also left with cheek kisses and hugs and some of the parents were also leaving the house and sunset began to rise.

Elizabeth's POV

I watch Zoë kiss Y/N on the cheek and walk away, I assume to her car to leave but she stops near Scarlett. I'm pissed, how dare she kiss my Y/N. Wait it could've been a friendly thing, like a greeting, No I'm still pissed.

MK: Are you okay? You look lost in thought.

Elizabeth: I'm fine I was just thinking if cats have nine lives.

Ashley: Okay that's weird. I'm going to go get some extra cake.

3rd Person POV

Zoe was chatting with Scarlett as the two are good friends.

Zoë: I did like him, I mean look at him, but it was clear from the beginning that it would never work, I'm not what he wants.

Scarlett: And what's that?

Zoë: Elizabeth, I'm not her. So just because I couldn't try with him. I became his friend.

Scarlett: Are you happy with just being a friend?

Zoë: 100%. You say it like it's a bad thing to be friends with an amazing guy, I have no motives to get with him but I still value his friendship.

Scarlett is momentarily stunned, she was so concerned with protecting Elizabeth she never actually realised that they could just be good friends, a friendship she has with Chris Evans.

Scarlett: Friends or not I believe Elizabeth might kill you for the kiss on the cheek.

Zoë: You might be right, seeing me here made her look angry and the kiss was the nail on the coffin. Thank God I didn't wear the skin tight Catwoman suit or I'm I would've been leaving in an ambulance.

She walks off to her car as the two laugh.

Zoë: Bye, Scarlett.

Scarlett: (Laughing) Goodbye Zoë.

-

Everyone ended up leaving and headed home, as for Y/N, he was helping his son open up the abundance of presents he received.

Y/N: Oh wow! Grandma gave you this awesome 3 piece suit! Make sure to send her a thank you video.

William: Dad look at this!

Y/N: Wow! It's a Dominic Toretto car from Uncle Vin.

He takes the toy from his son examining it before handing it to him. As for Elizabeth, she was in her sleeping gown walking towards the Batmobile, she had a special flashlight to illuminate things on certain colors.

Elizabeth's POV

I finally remembered my mental note from earlier and now that they are busy opening presents I have my chance. I use the black light because there was rumours of Y/N and Zoë doing "things" in this car. I don't believe them as Y/N isn't like thay but I have to know.

After I scourer and search the car for any supposed "fun" and find nothing I head back into the house finding my two special men in the living room.

Elizabeth: William, how about we open the rest tomorrow. It's getting late and the bogeyman might get you.

The boy screams earning a confused look from Y/N. He gives me a 'really' look. The boy then jumps and runs upstairs as fast as he can and Y/N stands up revealing his hot body in those cute pajamas.

Y/N: Bogeyman. Really? Great parenting Lizzie.

I chuckle as he spoke sarcastically.

Elizabeth: Trust me it gets the job done.

We both walk upstairs and into Wills room who was in his bed.

Elizabeth: Did you brush and go to the toilet?

William: Yes mama.

Elizabeth: What about my goodnight kiss?

J spoke softly and went towards his bed, crouching and tucking him in, and giving him a kiss on the cheek.

Elizabeth: Goodnight my four year old Prince.

Y/N then comes over to do the same.

Y/N: Sweet dreams birthday boy.

We both walk away before he interrupts us.

William: Mommy and Daddy?

Y/N & Elizabeth: Yeah?

William: Thank you for giving me the best birthday ever. I love you.

Elizabeth: We love you too.

Y/N: I love you son.

We leave his room and Y/N then heads to the guest room where I said he could sleep tonight before he entered I spoke.

Elizabeth: Y/N.

He then turned with his soft E/C gaze.

Elizabeth: Thank you for this and keeping your promise.

He softly smiled and went to bed and I went to mine, I then remembered Will said to me last night that Y/N said I was hot. Oh no, the pool moment today. I'm gonna go to the shower real quick.
