Hmm, yeah I guess that could happen, AstroPhantom. But like I said in this blog, Alex Hirsch's tweet said "time in Gravity Falls is more emotional than literal". So that means since Alex is the creator of the show, summer in Gravity Falls can last as long as he wants it to. That's solid proof that this isn't the last episode. And also, since they said Bill will enter Gravity Falls with other demons. I wonder who those other demons are.
