Hm how about something akin to a handy man if allied with Kol. you know, someone to help Kol when he needs to get something. Naturally, with Edge wanting to have Kol's head stuffed and mounted over his cozy little fireplace, Kol cant always go out and collect what he needs. While a character like that would be very interesting, it is still entirely up to the guy what kind of character he wants to make and who he allies with (if anyone).
