Dipper cried out as the forces of the portal threw him into a wooden beam. He grabbed on and winced with pain.

''Dipper!'' Mabel yelled across the room. Her foot was caught in a wire near the shut off button.

''Mabel, hurry, shut it down!''

Mabel crawled down the long rope. The room shuddered and the portal swirled faster and faster, blinding colors shining out from it.

Stan kicked off the wall, ''No!'' he sailed through the air towards Mabel, a look of determination spread on her face. She grabbed on to the lever and raised her hand to end it.

''Mabel, Mabel, wait, stop!'' Stan was interrupted from a flying tackle. Soos grabbed onto him and they floated around fighting.

''Soos, what are you doing? I gave you an order!''

''Sorry Mr. Pines, if that is your real name, but I have a new mission now; Protecting these kids!''

Stan fought against Soos. ''Soos, you idiot, let me go!''

Dipper jumped off the wooden pillar and crashed into Soos and Stan, slapping and fighting eachother.

''Mabel! Press the red button! Shut it down!'' Dipper yelled.

Stan pushed him away. ''No, you can't! You gotta trust me!''

''Grunkle Stan! I don't even know if you're my Grunkle..'' Mabel started to shed tears. ''I wanna believe you, but..''

''Then listen to me! Remember this morning when I said I wanted to tell you guys something?''

The portal flashed brightly at twenty seconds, and a massive surge of energy shot Dipper, Soos, and Stan back against the wall.

Mabel raised her fist to press the button.

''I wanted to say that you're gonna hear some bad things about me,'' He sighed, ''And some of them are true. But trust me, everything I've worked for, everything I care about, It's all for this family!''

Dipper chimed in, ''Mabel, what if he's lying? This thing could destroy the universe, listen to your head!''

The portal swirled with incredible force.

''Look into my eyes, Mabel!'' Stan cried out. ''Do you really think I'm a bad guy?''

''He's lying! Shut it down now!''

''Mabel, please!''

The timer began to count down from ten.

Mabel slowly pushed her hand towards the button, before stopping.

''I trust you.'' Mabel released her hands and floated up towards the portal.

''Mabel are you crazy!?'' Dipper screamed, ''We're all gonna d-''

The portal exploded into flashing colors, and a bright white flashed. Dipper, Mabel, Grunkle Stan, and Soos screamed as the light consumed them.

Mabel felt like she was being sucked into something, she turned around to see the portal. She was going to be pulled in!

She desperately tried to grab hold to something, but it was too bright to see, and-

The town shuddered and dropped down to the earth. The portal fell apart, smoke pouring from the hole. Dipper, Soos, and Stan fell to the ground.

Dipper rubbed his head.

''What was, Stan?!'' Dipper shouted angrily. ''What was supposed to happen? The universe falling apart? Why would you even want that?!''

Grunkle Stan's eyes widened. ''No, I couldn't have messed that up, NO!''

Dipper stumbled around, before realizing, ''Where's Mabel..?''

He looked to the portal.

''No! NOOO!''

He grabbed Stan by the shirt, and punched him in the jaw. Stan, in a state of shock, didn't respond.

''MABEL IS GONE!'' He kicked Stan. ''AND IT'S YOUR FAULT!''

Stan whimpered. ''Stanford.. and Mabel..''

''They're gone.''

Hey guys! New fanfic! This is my first Gravity Falls fanfiction, so if I don't portray the characters really well, then It's because first times. This fic takes place in an AU where Mabel got sucked into the portal and Stanford never came out, leaving Dipper and Stanley in a terrible, grieving state. And while one set of characters try to fix the portal, Mabel and Stanford get some nice bonding and discover a few things out there in portal-land!

Chapter two coming soon!
