They are on the right side of the bus

To say goodbye

There’s the Water Tower to the left.



And now they are on the left side just to look at it.

They have their bags on the left side too.

Finally, they are on the right side of the bus again

I think they put their bags on the left side of the bus and sat in the right side to be more comfortable, or to play bus seat treasure hunt.

There doesn’t seem to be any luggage in the floor when Mabel is asleep and Dipper takes out Wendy’s letter.



They just ran to the left window when they passed by the Water Tower just to take a last look at it, and luckily to Northwest Manor too. To say one final goodbye to Gravity Falls.

Then, they went back to the right side and Mabel felt sleepy.

If that is how things happened, that is something really nice.

This final scene… I don’t know, they had to make more turns in the mountain, or Gravity Falls strange geography, or this is before all the pictures above or error, or they just made the final frigging amazing and beautiful goodbye scene they wanted.

Probably the most emotional minutes of the episode… and the entire series.
