HI GUYS!! Jill here with a third character because I am masochistic!!
John is a loner, a pretty dark and angry fella whose bad feelings tend to make him reckless and fearless. He's never lived in the safehouses, preferring to travel around on his own. He collects classic weapons, his favorites being a hewing axe and a Blunderbuss, and can sometimes be found stalking into groups of shufflers and going off on them. He's immune, or he would have been a goner a hundred times over before now. He's been traveling in the vicinity of Sing Sing lately, has noticed some activity in the area, and is about to come investigate on his way out of town...
There's a smidge of a plan for Rodeo to find him, engage in an epic fight, and then lock him up tight in one of Sing Sing's cells as the first non-safehouse-oriented prisoner.
