Gravity Falls: Comet (Male Reader X Mabel Pines)

Blendin's Game

Happy birthday Dipper and Mabel Pines. They're now 23! Bet you feel pretty old now, don't you?

The scene opens to the Infinetentiary in the year 207̃012. Blendin Blandin has escaped from prison and is wearing a cloak, Lolph and Dundgren are chasing him. "Halt!"

Dundgren admitted, "I've got to hand it to this perp, no one's broken out of the Infinitentiary before."

Lolph explained, "He's either the bravest time convict I've ever seen, or the dumbest."

Blendin Blandin turns and runs into wall, "Ow! (Stumbles into barrels and falls over causing his face to be revealed) Oh! My time-knee! Oh, time-dang it!"

Dundgren stated, "Definitely the dumbest."

Lolph raised up the weapon, "Freeze! You're surrounded by the Time Paradox Avoidance Enforcement Squadron. Anything you say can and already has been used against you in future court."

Dundgren shouted, "This is it, Blendin. End of the timeline. Any last words?"

Blendin shouted, "Uh-uh-uh-uh-I-I-I-I... I INVOKE GLOBNAR!"

The Crowd talks about Globnar, Dundgren stops, "Very well, speak the name and century of those accused."

Blendin glared, "The three kids that ruined my life: Dipper and Mabel Pines and Y/n L/n. 21st century."

Dundgren's tablet searches and finds a clip of Dipper and Mabel hitting each other with baseball bats and laughing. A clip of Y/n flipping his eyepatch up is shown. The clips are shown on every screen in the shot, with the words 'GLOBNAR TRIBUTES' over it. Lolph stated, "So be it. May Time Baby have mercy on their souls."

A flashback cuts to the scene when Mabel and Dipper stole the time machine, "Here it is, Mabel. Our ticket to any moment in history."

Mabel smiled, "Let's go get two dodos and force them to make out!"

Dipper shakes his head, "No! We gotta be smart about this. All that paradox talk kinda freaked me out. All I'm gonna do is go back and fix my one mistake. If I don't miss that base ball throw, I won't hit Wendy in the eye, and Robbie won't comfort her, and they won't start going out."

"I'm coming, too! I wanna relive the greatest moment in my life: winning Waddles." Mabel kisses Waddles.

Mabel then remembers, "wait! What about Y/n? We not gonna invite him?"

"Come on, he's been on every adventure we've been on. I think he understands." Dipper pulls out tape, "See you later."

Mabel smiled, "See you earlier! Ha yuk yuk yuk!"

Dipper releases the tape and high fives Mabel, making them both freeze. Waddles runs away, knocking a pile of cards of the table. He and the cards freeze. Soos eats half a sandwich, then freezes mid bite. Pizza Man throws a ball, which freezes, and he does too. Y/n is seen gripping his head and screaming in pain while being surrounded with blue flames. The scene now continues with Y/n laughing with blue flames, before the flames die down and Bill takes over. "Finally, a real pep in my step eh? Eh?"

Bill snaps his fingers and opens a portal on the ground, Bill somehow looks through time. "Hmm, so he ends up joining the others. If the reincarnation did work and I shouted 'that backwards message', then I should've been sent back. Comet should be exactly like me, did the memory process get messed up? Or is it because I couldn't interact with him until now...? Course! If he had no memory of us plus a new life, he wouldn't be 'me.' Those Blind Eye Society losers...! I got reincarnated to be such a wimp...Then I better make sure I can make him use more of my power to jog that noggin. Worst comes to worst, take over that body. Probably flush his soul down the bottomless pits of hell and make the body leap off the Water Tower. They'll just think Comet lost his mind while two of me run around...but how would I...?"
