none of the Pines family or Wendy have to end up in a relationship; they realize what’s realy important to them and that’s okay. And these characters who do end up in relationships get to be very happy with their partners despite the fact that nobody believed they could. This show means so much.
When the rest of the Gravity Falls fandom is like this, while I'm over here like: "This is a good cartoon and I have no suspicions, and have not spotted a single puzzle in the show on my own, nor solved one!" ;-;
