"The Boxer" (Gravity Falls) on AO3, gen, contains a few brief flashes. A character study of Stan Pines, who most people can probably figure by now is my favorite character, with some parallels drawn to Dipper Pines.

Although I've finished this, I'm probably going to try to go back and make a few other exercises for the alternate source I was playing with. I'm having fun, but will take a little break!
