I'd like to play someone just barely under what the White Council considers for admission, but uses what he has very, very well.
He trades work for training and some cash, and has been at it for quite some time before the war doing small work for various wardens.
When its a minor job like investigating a rumor of a haunting, an ugly death that may have supernatural overtones, or just going in to have a drink in a Red Court owned bar to see whats going on, he takes it.
When its a dirty job like eliminating a pawn of the Reds, B&E to plant a bug or picking up a dead-drop message, he does that too.
He tries to be more unobtrusive than deadly, and succeeds for the most part, but obviously, when dealing with vampires & fae, not to mention humans working for vampires & fae, you learn to pull the trigger (or hit that detonator) without hesitation.
He has previously worked with various Wardens in various minor capacities as an additional "hired gun" as well as setting up safe houses, clean cars, prepaid cell phones...things like that.
After the events in Dead Beat with the Wardens being almost decimated he has been getting more, and more important, assignments. The Wardens, after all, can hardly afford to be picky in their help no matter how much they'd like to be.
In the past few years with the war on his trade of work for training has enabled him to gather up a rather tidy bit of power. If tested again, he would probably make the Council...if anyone noticed, as he has been somewhat labeled into his current roll.
