So I have a headcanon that over the course of the summer Stan slowly but surely, becomes enamored with the cartoons Mabel watches. (I mean he’s a huge fan of Ducktective, and we see how he becomes emotionally involved with the Dutchess Approves). Every time he walks by the tv where she is watching it, he absorbs more and more weird details. Until he is eventually pretending to read the newspaper, but peaking over it to see how the episode ends because- oh no the pony pals have to overcome their differences and use the pony pal power of friendship to save the day right?? Until one day Candy, Grenda and Mabel are all arguing about theories about the show and Stan just blurts out “That’s obviously not gonna happen! Evil Prince Dunkoroo hasn’t even stolen all of the Friendship Power Crystals! Er, I mean… *cough* (but it’s too late and all the girls squeal and tackle him. and then later they all watch the new episode together and Mabel makes Stan a Pony Pals sweater which he wears secretly)
What if Graves first name wasn't actually Percival. That he had changed it to Percival from Perseverance because his parents are evil.
