Imagine this

You are at the comic con with Alex and Jason and you are voicing Mabel. The audience asks questions or dares you and you guys have to answer them or do what they say.

...

This is gonna be so much fun.

Guy: Jason, i dare you to lick your elbow.

Jason: sure it isn't so hard! *tries and fails*

YOU KNOW SOMETHING

I'M NOT SOOS BRO!

you: *laughs* well

Alex: *does Soos voice* I am!

Jason: Here do it!

Alex: *back to normal voice* no way! Next ask-dare!

Girl: so.. I really like pinecest.. Don't judge me Alex, i am not sorry! As Dipper is based heavily on you and
y/n is voicing Mabel that is based on your twin sis, i would like you to propose to Y/n!

Alex: *red af*
