Just a quick rundown of the new trailer before bed because it’s very, very late over here.
We now know for sure McGucket is going to play a part in the next episode, and I reckon it’ll be a big one. We also know the floating thing that happened in the teaser is probably connected to the Apocalypse. Of particular interest is this;
We can see freeze-frames of McGucket in between the scene here with Lazy Susan and Tyler and the one with Mabel. From what I can tell, McGucket is either skipping town or taking something in a bag to the building we can just about see on the left. I’m not sure it’s the Mystery Shack - the shape seems off to me. Then again, I could be wrong.
The gravity also fails in the agent’s interrogation room, which means that, if this is a localised event, they are interrogating him in the town of Gravity Falls.
Last thing I noticed is here;
Stan is running and looking at his watch. This seems to indicate that he knows what McGucket knows and either thinks he can stop it or is trying to find the twins and perhaps save them from the end. The light trail behind Stan’s head also strike me somewhat suspicious, but I won’t make a stone verdict on that.
What if “Stanley” isn’t Stan’s twin but this universe’s original Stan. We know the portal can go into other universes; what if who we know as Grunkle Stan was Stan from another universe and somehow the two got switched? And AU Stan is trying to get Original!Stan back to this reality and himself to his own universe?
