Rollie junkdrawer

Rollie takes notes. Almost compulsively. He uses a homemade shorthand system that is loosely based off runes. He got mocked for it as a boy so he hides it instintively now. His friend Steve knows how to infer Rollie's emotional state by looking at his runes, even though he can barely figure it out.

Steve thinks Rollie isn't a genius, but has a weird enough brain that he sees patterns when other people don't, and doesn't see the obvious when other people do.
