Your POV

I had woken up on the hard ground with a groan, my neck ached a bit from how uncomfortable I had been during my sleep.

I looked around to see myself in a sort of familiar place: the one with no walls, no floor, no roof.

Yeah, I remembered this place. I had a nightmare here days ago. It was confusing most of all.

"Maybe I can clear your confusion...?" A sudden voice startled me. It was familiar enough, and it didn't take me long to know who it was.

You: ... *sigh* What do you want, Bill...?

Bill: I just wanted to see how you were doing...

You: Not so great at the moment, why am I here?

Bill: I want to talk to you...

You: If you're trying to get me to take you back again, the answer is no. I'm with someone else.

Bill: You're with Pinetree, I know... But (y/n), I need to warn you about him...!

You: About him?!? What about you?!? After all you've put us through?!?

Bill: I-I know, but just hear me out...!

You: *growl a bit* Fine, what.

Bill: Just-... don't get too close to him. He might hurt you a lot in the near future.

You: You mean like you did?

Bill: ... I know you're mad at me, about everything, but... I just need you to trust me with time, Fireheart.

You: I'm sorry, Bill, but I can't. Not this time.

Bill: ... *glares at you* Fine, have it your way. But sooner or later, you'll see I was right. *disappears*

It wasn't soon until I woke up. I was angry at Bill, but a part my started to worry...

Could he be right...?

No, Dipper wasn't like that. Even before we were together, he has been my best friend since I first met him. Sure, he'd sometimes let his pride get in the way of his brain, but he'd always come around in the end.

I sneaked out of my house, going to the Mystery Shack. Mabel was now wearing some sunglasses and a sombrero, Dipper had a checklist, Soos hada piñata, and I had my journal. Mabel had assigned me to do a special painting for the party.

Mabel: Hey, (y/n)!!!

You: Hey guys.

Dipper: (y/n), you're here!

You: Yeah. Sorry for taking a bit, overslept.

Mabel: Alright, party planners, in one week we become teenagers and our summer vacation winds to an end, so we need to throw the greatest party of all time!!! I'm talking piñatas with tinier piñatas inside!!!

Soos: *as he pores candy into a piñata* Boom, dreams coming true!!!

Mabel: I'm talking inviting everyone in town!!! *takes Dipper's notebook and pen* Let's see, where do we stand with the gnomes...?!?

You: Eh.

Stan: *enters* Not so fast, doofus and girl doofuses. After that zombie incident no one's throwing another party at my house! I keep fighting little bits of the undead in the couch cushion. *throws the bat which you catch*

Mabel: But Grunkle Stan, we need some roof to raise!!!

You: What about renting the Gravity Falls high school gym?

Soos: Yeah dude, t's empty all summer long!

Mabel: The gym's a great idea, guys!!! To the high school!!!

Suddenly the ground shook harshly making us all scream. Suddenly we heard Ford yell: "Dipper, my face is on fire!!!" making Dipper run out of the room.

Dipper's POV

I ran to the room Ford was in.

Dipper: Great uncle Ford, are you ok?!?

Ford: Oh yes, I'm fine. I just said that to make sure you'd come in here quickly.

Dipper: But your face is on fire!

Ford: *pats away the flames* Yes, it's must faster than shaving. Now listen, Dipper, we have a very important mission and you are the only one that can help me. *takes out the rift orb* Remember the rift in dimensional space time I showed you? It's cracking. This is what Bill has been waiting for, if it breaks it would cause reality as we know it to completely unravel! A hypothetical and catastrophic event I call Weirdmageddon.

Dipper: *stares at the chalkboard in shock*

Ford: Bill is out there, and he'd use any trick, from deception to outright possession to make this happen. But for the sake of humanity we mustn't let it!

Dipper: What do we do?!?

Ford: We patch the rift. *puts the rift orb in a case* I'll explain on the way.

Dipper: Oh wait, what about Mabel and (y/n)?!?

You: *leaning against the doorway* It's ok, Pine Hat.

Mabel: *besides you holding two bags* You should totally go with Grunkle Ford to save the world or whatever!

Dipper: Are you sure?

Mabel: We're gonna be doing birthday junk all week!

You: Plus she made me pack you this bag.

Mabel: Here's one for my party mission and one for your smarty mission!

You, Dipper, and Mabel: *laugh*

Ford: *clears his throat* I did mention that the fate of the universe is at stake, didn't I? Hurry, we haven't much time!

Dipper: *whispers to himself* Ok Dipper, it's your first big mission with Ford, a chance to prove yourself!

You: *playfully pull his hat down* Good luck!

Dipper: *smiles softly before running after Ford*

Your POV

We left to go to the school gym. When we entered there was a lot of people in lines.

Mabel: Whoa, I thought you guys said this place was empty!

You: It usually is.

Wendy: *from the line* My dogs, what up!

Mabel: *runs over followed by you and Soos* Wendy!!! What are you doing here?!?

Wendy: *groans* High school registration.

Mabel: Ooh!!! *wraps an arm around you* You know we're only a year away from high school ourselves!!! *moves her arm away* Would you say your experience is more rom-com or wacky rom?!?

Wendy: More like teen horror movie!!! High school is the worst!!! Classes get super hard, your body just flat out turns against you, and worst of all, everybody hates you!!! *points at the angry, scared, sad teens in the other side of the room*

Mabel: Why aren't they singing about following their dreams?!? Tv taught me that high school is like some sort of musical!

Wendy: Tv lied, man!!! If you could avoid growing up, do it!!! I'd give anything to be twelve again... Anyways, what are you guys doing here?

Mabel: Oho, just looking for a place to have my 13th birthday party...

You: *put your hand on Mabel's shoulder* ...

Man: Wendy-... Boarduroy? I-I mean Corduroy?

Teens: *laugh at Wendy*

Wendy: *growls* See what I mean? *goes over to the table*

Mabel: ... *goes outside*

You: *follow Mabel and see her talking to the walkie talkie as she sits in the steps*

Mabel: Master Mabel to Dippity Dog, we can have our party at the gym but we gotta talk about high school... I'm starting to think it might not be he awesome future we were expecting, over...

Dipper: *through the walkie talkie as his voice sounds through the static* I'm going through a bad patch, Mabel. We'll talk when I get back.

Mabel: Dipper?!? Come in?!? Come in?!? *sigh*

You: Hey, don't worry, I'm sure it's not as bad as it seems.

Mabel: I don't know, (y/n)...

You: Reassuring friend hug?

Mabel: *looks at you sadly*

You: *raise your arms for a hug*

Mabel: *hugs you*

You: And if things do turn south, you still have Dipper watching your back.

Mabel: I wish you could move to California with us.

You: *chuckle* I would love to, but I don't think your parents would like another kid.

Mabel: ...

You: I know what will cheer you up. Let's deliver some invites to your friends, ok?

Mabel: *pulls away* Yeah!

The first house we went to was Grenda's. I stayed in the car with Soos, but I could hear the conversation.

Mabel: *knocks on the door*

Grenda: *opens the door* Oh hi Mabel!!!

Candy: *walks out with Grenda*

Grenda: You're just in time for our one o'clock boy talk!!!

Mabel: If you think that's good... *shows her friends the birthday invitation* Boom!!! Me and Dipper's 13th birthday jam!!!

Grenda: *takes the invitation* Aw man, your birthday's in the last day of summer?!? I'm not gonna be here!!!

Mabel: What...?!?

Grenda: Marius is flying me out to Austria to hang out at his castle or whatever that week. He's so clingy!!!

Mabel: You're gonna be out of town for my birthday...?!? But at least you can come, right Candy?!?

Candy: Sorry Mabel, my parents send me to music camp this time of year. There is no escape from music.

Mabel: So neither of you are gonna be at my birthday party...?!? And you want be able to wish me goodbye at the end of summer...?!?

Candy and Grenda: *hug Mabel*

Candy: I'm sorry, Mabel...

Grenda: Summer happened so fast... *picks her now ringing phone* Ugh, Marius!!! Now's not the time!!! *picks it up and goes back inside*

Candy: *pulls away*

Mabel: I think I need to radio for emotional back up... *starts walking to the car* Dipper, please come in, our party mission is going down in flames, over... *hears the static and sighs, then enters the car*

You: I'm so sorry, M...

Mabel: It's ok, it's not your fault...

We arrived home. I had never seen Mabel in such a sad mood. We went to our room, she laud on the floor looking through her scrapbook with Waddles beside her.

Stan: *enters* Hey, everything alright, pumpkin?

Mabel: *sigh* I just can't believe the summer's almost over... And now that I know how awful high school is going to be I'm in no hurry to start that train wreck...

Stan: Ah, nobody likes getting older, but just because you're growing up doesn't mean you have to grow up, you know? I mean look at me! I'm pushing seventy and I still eat ice cream for diner!

Mabel: But I don't want to say goodbye to Gravity Falls...

Stan: Hey, at least whatever happened this summer you'll still have your brother along with you through think and thin. Not everyone can say that, you know? *ruffles Mabel's hair, then leaves*

Mabel: ... I need to go to the bathroom... *leaves*

I sat on her bed, waiting for her to return. I started to hear static coming from Mabel's backpack. I got her walkie talkie, I began to hear Dipper and Ford's voices.

Ford: Listen to me, Dipper. This town is a magnet for things that are special, and that includes you and me. It brought both of us here for a purpose. Stay here with me, Dipper. Become my apprentice, don't let anyone hold you- *coughs*

Dipper: I'll do it. I'm gonna stay.

Ford: Excellent! Now who wants to save the world, apprentice?

I went pale as I heard this. He was staying with Ford...?

You'd think that would make me happy, but I know that he'd just stay down in the basement forever.

He'd be leaving both Mabel and me...

"(y/n)?" I heard Mabel and turned to see her by the door, looking at me worriedly.

~~~~~~~~~~~~~~~~~~~~~~~~~

Dipper: *enters* Girls! I just had the best day of my life! UFOs are real and there's one under the town and I sent great uncle Ford's life and-!

You: *raise your hand, signaling him to stop* ...

Dipper: ... Is everything ok?

Mabel: Tell me it's not true, Dipper... *turns around, showing him the walkie talkie* Tell me you were joking...!

Dipper: !!!

You: We heard everything...

Mabel: Ford's apprentice...?!? Seriously...?!?

Dipper: Look, I was thinking and... this is a huge opportunity for me...!

Mabel: *as tears form in her eyes* Well it's a horrible opportunity for me!

Dipper: ...

Mabel: I had the worst day of my life! When we turn thirteen, summer ends, and I have to leave everything behind! You're the only person I can count on and now you're leaving me too...?!?

Dipper: Look, I've been thinking about it! I won't be gone forever, ok? I'll still visit you at home, and we can chat online, we'll make it work!

Mabel: I don't want it to work...! I just wish summer could last forever...!

Dipper: But it can't, Mabel... Look, things aren't gonna stay frozen this way... It's part of growing up... Things change... Summer ends...

Mabel: ... *runs away*

Dipper: !!! Mabel, wait!!! *is about to run away when you grab him by his vest* !

You: Let me talk to her...

Dipper: ... *hesitates, but nods*

I ran out after Mabel. As much as I understood where Mabel was coming from, Dipper had his own good point as well.

I found her in the woods sitting against a tree, her face buried inside her sweater.

You: ... Mabel...?

Mabel: *looks up* (y-y/n)...?

You: *sit beside her, placing a hand on her shoulder* I'm sorry about everything...

Mabel: It's not your fault... I just wish summer could last a bit longer...

Voice: That might be possible...

You: !

Mabel: Sweater Town is not accepting incoming calls right now...

Voice: M-M-Mabel, it's me!

Mabel: What...?

You: Uh, who said that...?

Blendin: *as he walks over* I- I- I can help!

You: Aren't you the time traveler guy...?

Mabel: What are you doing here...?

Blendin: Y-you said you don't want summer to end, right? D- d- did I here that right?

Mabel: Yeah... why are you asking...?

Blendin: Look, maybe it's against the rules, but I thought I could help you out! It's called a time bubble, and it prevents time from going forward! Summer in Gravity Falls can last as long as you wanted to!

You: *try to protest, but are unable to move or talk* !

Mabel: Really...? But how does it work...?

Blendin: I just need you to get me a little gizmo for me from your uncle. *shows her a hologram of the rift* He won't even know it's missing!

Mabel: Huh. Maybe Dipper has something like that in his nerd back. *searches through the bag, finding the rift* ... huh. That's... odd... Is this is...?

Blendin: Yes, that's it! Just hand it over and I'll do my thing! Unless you're ready to leave Gravity Falls~!

You: *trying your best to move or speak*

Mabel: ... just a little more summer... *offers the rift*

Blendin: *takes it, but lets it fall and break* Oops!

Mabel: !!! What?!?

Blendin: *starts cackling evilly as he completely breaks the rift container, taking off his goggles and revealing his yellow eyes*

You: !!!

Mabel: Oh no!!! Wait wait wait!!!

Blendin: *snaps his fingers, knocking Mabel unconscious before fainting, Bill coming out of him*

Bill: At last!!! At long long last!!! The gate between worlds is broken!!! The event of one billion years prophecized is finally happening!!! The day has come, the world is finally mine!!! Ahahaha, HAHAHAHAHAHA!!!!

Thanks for reading!!! 'Till next time!!!
