"MAN! I AM LOVING THIS DIMENSION, YOU GUYS PARTYING HARD ENOUGH?"
A resounding yes came from the various extra dimensional beings partying in Bill's new castle.
The plans Bill had, first tricking the oh-so-gullible Stanford into punching a hole in reality, then piloting Gideon into a scenario where he HAD to call for Bill's help. Finally, the icing on the cake, having little miss Shooting Star, the kid everyone trusted most, hand him the keys to victory. Boy this was sweet.
"OKAY GUYS, I'M GOING TO GRAB SOME MORE TIME PUNCH, BRB." Bill floated into an adjacent room and pulled a large hourglass from the fridge.
"You know, drinking that stuff's not too good for you…." Bill sighed as he heard the voice behind him.
"OH GREAT, WADDYA WANT, Q? COME TO RAIN ON MY PARADE?"
"Don't worry, I'm not the one that's going to be doing that. But I certainly will stick around to watch."
"PLEASE, WHO'SE GONNA STOP ME! TIME BABY? KID'LL TAKE 1000 YEARS TO RECONSTITUTE."
"Yes, I saw your little show with the poor kid. Really you were too hard on him. Seems like you were the one throwing a tantrum."
"NO ONE'S GONNA GET IN THE WAY OF WHAT I HAVE PLANNED, NOT TIME BABY, NOT YOU. IF YOU HAVEN'T NOTICED I'M ALL POWERFUL HERE, SO WHY DON'T YOU SCRAM!" Bill shouted, even louder than usual and fired a beam of pure destruction at Q, vaporizing him in a flash of light. "NOW, THAT TAKES CARE OF THAT."
Turning to leave, he noticed Q standing in the doorway, hair slightly disheveled but ultimately no worse for wear. Q snapped his fingers, teleporting him and Bill into another dimension, one of pure nothingness. "Now listen here you ISOCELES IGNORAMUS. The only thing you have done here is annoy me, and were it not for the Continuum breathing down my neck you would be suffering a fate worse than anything imaginable. They sent me here to warn you, Bill. Destroy this dimension like you did the last, and your fate is sealed. Now the way I see it, it already is." Q snapped his fingers once again. Returning Bill to his pyramid and returning to the Continuum.
"Stupid Q" Bill muttered under his breath as he returned with the time punch. "Can't he just stick to messing with his own batch of humans…."
Elsewhere in Gravity Falls, a mound of dirt appeared in a flash of light, next to a canyon. Nothing too big, but if you get enough speed, you just might be able to ramp a car off of it.
