I haven't yet played in a game but I was thinking along the lines of a therapist who specializes in helping people deal with PTSD. The only thing she ever uses her magic for during work is her Sight to see if there has been supernatural tampering, plus she is a sensitive (kinda like Molly I guess?). That way, she is helping all kinds of people. When there is evidence of bad supernatural mojo, she can go in and put a stop to it (covertly or not, depending on the situation).
