It all began with the headaches. Normally everyone gets headaches every now and then, plus being the adopted child of two famous Avengers, going to school and learning the ways of the Mystic Arts can be stressful enough as it is. But do people get headaches every day? Raise your hands if you do.

I was currently doing some magical combinations when my mom opened my door knocking on it and said.

"Knock, knock."

"Can't you wait for me to give you permission to enter my room?" I asked her.

"I'm your mother (Y/n). Nothing you have is private to me." She teased. I shook my head at her and started the combinations again, "Got that magical test coming up?"

"More like an exam. Strange says that my form is good it's just that I'm not focused enough to actually bring out the shields and weapons. Then again it could just be because of the headaches."

"You're still having them? (Y/n) why haven't you told us?"

"I don't wanna worry you guys. Besides this month is finals week not only with my magical skills but also my 'real life' that you and dad want me to have."

"Okay. But if this isn't going away by the time all your finals are done, we're taking you to the doctors. Not Strange, a real doctor. To find out what's going on."

"You do know he was like the world's best neurosurgeon before he became the Sorcerer Supreme right?"

"I know. I already have to deal with Stark's ego every day, I'd rather not have my own daughter's doctor be just as arrogant and egotistical as Tony Stark." She came over and kissed the top of my head. "Now come on, dinner's being made and Wanda says she needs hers and Vision's taste tester."

"Tell them I'll be right down. Just gotta clear things up here."

"Alright but don't strain yourself. And if after you eat your headaches are still going on, maybe take some Tylenol."

"I will mom."

"Love you."

"Love you too." She kissed the top of my head before leaving my room leaving the door open. I closed my practice books but as I sat up, my legs suddenly felt like jelly and I nearly fell forward. "Whoa. Headrush. Okay—deep breaths." I took a couple of deep breaths before taking one small step forward and putting slight pressure on that leg until I was steady and I was finally able to leave my room.

I arrived at the kitchen and right there was Wanda and Vis prepping what looked like a Southern style meal. Cheese straws, hush puppies, gumbo and for dessert, moon pies.

"Ahh there you are. We've got everything ready but the gumbo feels a bit off. At least that's what Sam said. So we need a second opinion."

"Oh like mine wasn't good enough for yah red witch?" Sam exclaimed from the nearby table as he was setting down plates while Steve and Bucky were setting down the silverware and cups.

"That's cause no one wants to hear your opinion." Bucky sassed at him.

"Oh you say that now but wait until I start cooking the meals, I'll be sure to put a little something extra in your meal. And it won't be my spit."

"That's gross Sam you will do no such thing to poor Bucky." I said.

"Aww thanks (n/n). At least we know who is her favorite is." Bucky said.

"Enough you two clowns no arguing at the table." Steve said which made Bucky and Sam be quiet and continue setting up the table but staring each other down. I went over to Wanda and Vision and Vision said.

"We tried to add the correct amount of ingredients the gumbo needed but Sam said it was still missing something." Wanda dipped the wooden spoon in the pot and held it out for me. I took a taste and smacked my lips together. Humming to myself and trying to figure out the taste I then asked.

"We got any tabasco left over?"

"I think so. Vis look over in the top shelf right by the fridge." Wanda said as Vision walked over and opened the top cabinet, his fingers scanning over each spice that was there until he finally found the tabasco. He came over and handed it to me and I put in two drops of it, took the spoon from Wanda and stirred it up some more.

I took the spoon out and did another taste test and hummed in approval.

"There. Now it's perfect."

"Thank you sunray." She said as she thumbed my cheek gingerly before booping my nose. "Care to help us prepare the dishes?"

"Always." I said taking a bowl as Vis handed her a ladle and she poured some of the gumbo into my bowl and I walked over to the table and set it down at the head of the table. Soon more members of the team began piling in, getting in their seats and we all began eating supper.

"MM! See that's how you make great gumbo!" Sam exclaimed.

"All it needed was a couple drops of tabasco. It's not like Vis and I ruined it completely." Wanda said as she took a hushpuppy in her hand and then took a bite of it.

"Well just be grateful (Y/n) was here to correct you two on how food of the South should be made." Said Sam.

"Don't thank me. I owe it all to your sister Sam. By the way is she and the boys still coming up here next month?" I said.

"You bet. The boys have been going none stop asking about you."

"Now hold on hold on, what's this about your nephews talking about my daughter?" dad spoke up.

"Dad!" I whined.

"Ease on the breaks there papa hawk." Said mom gently nudging his arm.

"It's not even like that. They're still upset that I kicked their butt at Super Mario cart when I was playing as Princess Peaches while they were Mario and Yoshi." I explained.

"Okay. But it better be just because of that. Remember no boys till your 40. Or until I'm dead. Whichever comes first. And I don't planning on dying for a long time."

I waved off his statement as I took a bite of my hushpuppy when I was struck by a sharp feeling of pins and needles in my hand which made me drop my hushpuppy to the floor. I groaned and massaged my hand trying to rid of the feeling.

"You okay kiddo?" Tony asked.

"Yeah I—" all of a sudden my vision went black and felt myself falling from my chair and my world went dark.

*3rd Person POV*

With him being the closest person sitting next to her, Bucky immediately caught her before she fell to the ground and everyone gasped and all came up from their seats and circled over her.

"Give her some air back up!" Steve ordered as the only ones who were allowed to go to her were Natasha and Clint. Bucky handed (Y/n)'s unconscious body over to Nat and she stroked her daughter's face.

"(Y/n)? Baby girl can you hear me?"

"C'mon sweetheart c'mon. Open those beautiful (e/c) eyes of yours. Please do it for papa." Clint said taking her hand and checking her pulse. "Her pulse is very faint."

"We can't take her to a hospital the press will be all over us." Tony said.

"Get her to the medical wings and have Cho run some diagnostics on her. I'm gonna make a phone call." Bruce said. Clint took his daughter from Nat's arms and they all raced towards the medical wing while Bruce pulled out his phone and called Wong's number.

He waited for the phone to stop ringing and when Wong spoke up he said.

"Wong? Listen is Strange around? Yes I know I could just ask Strange for his number but this is a real emergency. It's (Y/n). Okay.....alright.....well she just passed out during dinner. But she's also been having extreme headaches, I even noticed how her hand was shaking. Alright. Yes.....okay tell him I'll meet him downstairs. Thanks Wong, yes bye." He hung up and soon enough a portal opened and in came in Stephen Strange.

"Where is she?" he demanded.

The Avengers all stayed outside of the room, most were sitting down anxiously bouncing their legs while the rest were pacing back and forth almost to the point where they would make a rut into the floor.

After what felt like hours (which was only 12 minutes), Stephen came out with a solemn expression on his face.

"How is she?" asked Nat as she walked up to him.

"She uhh—you all might want to sit down." At that phrase, each one of them knew this was something extremely serious and not even close to good news. "I talked with (Y/n) about her symptoms and I even got a closer look to see what exactly was going on in her head. And umm......there's no easy way to say this. Especially since I've seen this many times back in my surgeon days."

"You might as well just rip the band-aid off Doc because you're killing us here." Tony snapped. Stephen let out a heavy sigh and he told them.

"She has a Grade 4 brain tumor." At that everyone was speechless. No one knew what to say or even how to process the whole thing.

"A what?" asked Thor.

"Grade 4 brain tumor means it's practically incurable." Bruce explained to the Asgardian.

"For-for your mortal medicine maybe but if I took her to Asgard, our healers could heal her there."

"It wouldn't matter." Said Clint.

"What are you talking about of course it matters. She's your daughter Clint don't you care for her health and safety?!"

"Don't you ever say that I don't love (Y/n)! Don't you ever say that I don't care about her health and wellbeing!" Clint snapped angrily as he got up into Thor's face. Steve and Tony separated the two and Steve tried to calm Clint down by telling him.

"This isn't going to help any of us Clint." Clint shoved himself out of Steve's grip shaking his head and running his hands through his mohawk hair.

"I gave that girl a chance to have a father. I—I showed her how to shoot her first bow and arrow. She was a goddamn natural. I would give anything to take that tumor out of her and put it in me." Clint spoke in a broken tone. Natasha walked up to him and took his hand in hers.

The two super spies looked at each other before pressing their foreheads against one another, trying to draw in each other's strength as tears fell from both their eyes. After taking a deep breath Natasha spoke in a broken up voice.

"How long do you guess Stephen?"

"To be honest......" Stephen exhaled deeply rubbing the back of his neck. "Four months, maybe even less."

"What can we do?" asked Wanda. "I know that—removing it won't do much but—there has to be something to at least help her."

"There is. I can—connect you all to a former coworker of mine. Next to me, she's the best neurosurgeon in New York. I trust her with my own life. It won't be easy for her, especially with how fast this tumor is spreading so she's going to need everyone's support. Everyone's."

"She's already gotten it." Said Steve. "From the first day Nat and Clint brought her into our lives, she's always had it. Anything she needs, we'll give it to her. Whatever she needs help with, we'll help her. We're not gonna abandon her when she's given us so much hope and life to the team. Whatever it takes—we're gonna be there for her."

*My POV*

Life always finds a way of kicking you when your down. Just when you think you're on top of the world or feel like life is good, karma comes in and sweeps the leg.

Discovering that I had Stage 4 brain tumor and had maybe months to live it—it really made me think of just how much I had in my life. The people I've met, the friends I've made the—family that gave me a second chance (yeah I knew I was adopted but they still loved me as much as I loved them).

Still it—it didn't make what I had to experience any better, nor was it a cake walk. First I had to be pulled out of school and was basically homeschooled by Bruce and Tony (on the one upside, they never gave me any homework. Just tests and quizzes). It was best decided that I stopped my Mystic Arts training as just using my muscles started to become a problem.

Hell sometimes even just getting out of bed is hard because some days my body and muscles would ache so much, I had to be carried everywhere or (like a baby) be hand-fed by someone because I couldn't even lift my arm to grab a spoon or fork. And don't even get me started on the chemotherapy.

Sure Dr. Christine Palmer was nice and she helped me and my family out as much as she could, but the whole process was still scary to go through. Going into that large, tunnel-like machine, hearing the loud noises that came out of it, and of course the hair loss. The hair-loss in particular was difficult for me to swallow.

Not that I'm vain or anything but—my hair's always been special to me. When I was little, mom and I would braid each other's hair as she would tell me about my Aunt Yelena and their brief time together when they were kids, and then when Wanda came on the team, she taught me a little rhyme her and her mother used to say to each other as they would braid each other's hair.

Even dad, Bucky, Sam, and Steve would help style my hair for school or an upcoming event like when I was doing a school talent show or in a play. And when I was forced to lose it, it felt like all the memories I shared were now forever lost and were never going to come back.

It was bedtime and both my parents were tucking me in for the night. Dad handed me my evening pill for the pain while mom was tucking me under the covers.

"There we go, how's that? Comfy enough for you?"

"It's great mom." I said emotionlessly.

"Anything else we can do for you?" asked dad.

"I'm good, thanks." They were both silent for a moment until dad asked again.

"Wanna tell us what's going through your mind sweetheart?" A hidden tear fell at the corner of my eyes and I said to them.

"I'm scared guys. I—no I'm terrified. Every night when I shut my eyes I fear this is it, this is gonna be my last night on Earth."

"Oh sweetie." Mom softly cooed as both she and dad sat on each side of me.

"But that's not really the main thing that scares me, the thing that terrifies me the most is that—I don't know where I'm gonna go after I.....what if it's just a black abyss of nothingness? I'll be all alone, and you guys....."

"Death is always an uncertain and scary thing. It's something we can't control. But I doubt that you'll go to a place like that. You of all people don't deserve that." He told me.

"How can you be sure?" I asked him.

"Honestly, I can't. But I've got to have faith. Cause if I look up at the sky, up towards Heaven and I don't see your spirit in the form of a star every night, then the big guy and I are gonna have some problems." Dad gave a soft but broken smile as he leaned his forehead against mine.

"And......you guys? Will—will you be okay?"

"We'll—answer that question later. Right now you need to get some rest." Mom said. Dad helped adjust my position so that I was now laying on my back, my head resting on my pillow. He kissed my forehead before booping my nose softly.

"Night kiddo."

"G'night dad. G'night mom." I whispered as I felt mom's hand stroke my cheek.

"Goodnight my little one." She kissed my forehead as well before both she and dad left my room, turning off the light and shut the door. I let out a sigh and lay there for awhile staring at the ceiling until finally my eyes grew heavy and I had no choice but to close them.

*3rd Person POV*

The next morning, Natasha was the first to wake up so she decided to go and check on her daughter. Tying her silk red robe around her waist she silently snuck out of her room and headed over to (Y/n)'s room.

She quietly opened the door and closed it as carefully as she could before walking over to (Y/n) who was still sleeping soundly.

"(Y/n)? (Y/n). Time to wake up love." But as she carefully looked over her daughter there was something wrong. Her chest wasn't rising or falling anymore, plus she was lying too still for her liking. "(Y/n)?" Natasha's voice sounded more urgent as she sat very close to her daughter. Natasha placed her head over her chest to see if she could hear (Y/n)'s heartbeat. There was none.

She then felt around her neck still calling out (Y/n)'s name but once she felt around her pulse on her neck and felt that there was no heartbeat. Natasha shook her head in denial. No she couldn't be gone now. Not like this. She wasn't even with her when she promised her she would stay by her side in her final moments, but now—it was too late.

(Y/n) Barton-Romanoff was gone. Having died in her sleep last night and losing her battle to cancer.

The facility was dead quiet. No one really laughed anymore, no one cared to smile. What reason was there to when the light of the Avengers had been taken away from them so young and all too soon.

Steve, Bucky and Sam missed having their little workout buddy, Wanda and Vision didn't prepare homecooked meals as much anymore because they missed having their taste tester, Bruce and Tony they missed having some sort of smart-ass comment on how they should do a project one way when they were doing it another way. They sure did miss that especially, turns out a half year trip to Wakanda can improv a girl's smarts.

And Thor—well he was pretty much off world ever since the funeral. He just felt like there was hardly a reason to come down unless Earth truly needed him, the first young Midgardian he had taken under his wing had been snuffed away from him by a disease that not even Asgardians could cure for her.

Even Stephen Strange felt at fault. He was once the greatest neurosurgeon in America, had his hands still worked, he could've performed the surgery himself and removed the tumor himself but no.

Of course no one, absolutely no one was more heartbroken than the adopted parents themselves, Clint and Natasha. Together they raised that girl from the time she was rescued at the tender age of 5 and now—now she was just gone. Not from a mission gone wrong, not from alien threats, not even a simple mugger on the street.

No the biggest villain of all to take the Light of the Avengers away from them all, the one villain half the people in the whole world can't beat. Cancer.

Tony was going through some old files on the computer when he caught something that didn't seem to be related to any cases they worked.

"Friday open up file FARETHEEWELL."

'Yes boss.' FRIDAY's voice spoke up as the computer opened it up and Tony saw what was on it, his eyes widening as he quickly grabbed his phone and dialed the first number he could find.

"Happy, get everyone to the facility now. No, no it's not that—look I understand that this is your day off but I need you to call every member of the Avengers and get their butts up here right now! Why? Because I found one final message from the greatest member of the team."

Everyone gathered around within 45min after Tony made the call (well forced Happy make the call) in the living room.

"What's this about Tony?" asked Rhodey.

"I came across something while going through the archives. It's.....it's from (Y/n)." at hearing her name, all the Avengers looked up.

"Don't give me hope Tony." Clint said brokenly.

"This isn't a joke here Stark." Natasha said in the same manner but with a hint of anger in her tone.

"I'm not lying. FRIDAY pull it up on screen."

'Yes boss.' The TV in the living room soon turned on and there it showed (Y/n) sitting at her computer desk, her head wrapped up in a bandana to hide her then balding head. Even with as pale and sickly as she looked the day she made the video, there was still a spark of life in her eyes.

'Hey everyone. I uhh—hope you come across this. Hopefully after I'm gone otherwise this is just awkward.' She nervously chuckled which also made everyone chuckle sadly. 'I—I know things haven't been.....well easy since.....' she gestured to her head. 'But I—I just wanted to tell all of you thank you. Thank you for all the support, love and care you've given me. Especially throughout this whole cancer treatment.'

There were a few soft nods, broken smiles but everyone in that room all had tears in their eyes.

'I wanted to make this video to make sure that all of you also know something very important. This is not your fault. I know you guys are heroes, you've all been heroes to me. You think you have to save everyone, but the truth is not everyone can be saved. Especially someone like me. Cancer is—pardon my language, is a bitch. And sadly I got the short end of the stick in not recovering like some who get lucky and get pass this. What I want you all to know—is that this wasn't any of your faults. You can be sad and mourn for my death, but don't let my death dictate the lives that you all can still save. I believe in all of you. So go out and be the brave heroes I know you all to be. Honor my death by saving countless others. And know that I love each and every one of you. I love you 3000. And thank you for all the good times.' She pressed her hands together into a heart before the video ended with that still image right there. A warm, soft smile in her face.

After the message ended, everyone sat there in silence. Not a single person spoke a word but they all took (Y/n)'s word to heart and they all vowed after seeing that video to keep that promise to her.
