Well... Wait- I can't remember...
What was this Role play chapter about again?

Ohh right! Nobody (I repeat, NOBODY!!!) can remember each other! Were all in a huge grey room and can't remember a thing about the people around us or where we are.
The weird thing is- if you kill someone. They appear in the room again completely unharmed.

So you're back to yourself before you came to Gravity Falls.
So basically, the chapter will probably start with Nami trying to kill everyone. Have fun!
