One of my favorite things about Gravity Falls is how Stan’s more crooked nature is slowly rubbing off on Mabel. I just love how Gruncle Stan is taking Mabel under his wing as the next Pines family criminal mastermind.
I feel like the show is getting a lot of hints that Soos might die later in the series. The video game foreshadowed it, Bill Cipher (the near omnipotent dream demon) mentioned it and it seems like Soos has an unusual number of near-death experiences… If the Pines family were ever in danger, I could see Soos dying to protect them. Soos is the type of person to sacrifice everything if it meant protecting the people he cares about and the Pines definitely fall under that category.
