Well, in the past serials that I've seen, I've yet to see a character who had as much influence on the arcs and plotlines as 'Bad Wolf' Rose did. Perhaps that's yet to come.
Unless you mean in narrative importance to the Doctor, in which case... well, I still haven't seen all of the still-existing Who. So far, though, the only character that I would place as emotionally close to him, in what I've seen, is Susan.
