A quasi-refined preliminary sketch of (a) character(s) I've been working with.
Jelly is a homeless man who apparently at one time had a friend named PB who was killed in something of a "government conspiracy." PB's consciousness is now located in a cube (or an orb; I'm still debating) that is indefinitely confined to Jelly's hobo-satchel. P.B. speaks only to Jelly, and only through telepathy (directly into Jelly's mind). This leads everyone who confronts Jelly to assume that he is a crazy.
Anyway, here's a drawing (click on it for super-large version):
