Mine are all mostly silly.
The majority of the MC's action figures were bought by Prodigal, threats of violence were involved. Jury, being something of a closet nerd, also has your action figure (he hides it in a drawer and probably poses it funny when he's mad at you.)
Jury's a bit of a mama's boy.
The MC (at least mine) has some heightened senses, especially smell. (Inspired by the author writing that the MC tends to notice how people smell. Especially Lucky. "He smells just like I remember!" But you haven't seen him since you were twelve! WHAT. Someone get this man a bath, ASAP.)
As a kid, Jury's favourite heroes were the MC's parents and he felt incredibly betrayed by them when they were arrested. (So if you romance him, he's close to shitting himself for about ten different reasons when he meets them.)
CCH/HR: Stunner and Fistfull would be BFFs until a falling out after a particularly aggressive arm wrestling and/or flexing competition. They make up after the re-match.
