Leslie Nakamura: Fixer: Met way back when she dropped out of college. She was the gir on campus who knew it all, knew what clubs were hopping, who was here, what to get, where to get it and who to get it from, and who needed what, but most importantly, where to get rid of stuff for a decent price (minus a commission). Now, she's past the campus and on the streets with wide reaching fingers into many pots. She's morally ambiguous, and in D&D terms, would be deemed as Financialy Neutral.
Jason Lacroix: Street Sam: Met during a shootout. She was smart enough to dive behind the right car, he was lucky enough to have a gun jam, and even luckier to have it handed back in perfect working order after it was thrown down. After that, she became a source of explosive for what he needed, and he became a little muscle and knew enough people to get stuff when she needed. Not around a lot, but still knoes the redhead when she calls.
<I need a name>:Public Investigator: Ex-cop, and knoes Jessie's bomb signatures, but likes her too much too much to turn her over for her past crimes. Off the firce after punching his superior and breaking their jaw cause of a little misunderstanding concerning an investigation. Now a ver gruffled and good PI. Still with buddies on the force, and in the streets.
