Ohh, totally down with either of the two. I guess The Artful Dodger and the Medium should have something going on, since they seem to be trickster buddies and all that.
Also wouldn't mind running into the Vampire Hunter. It's since been worked out that young Jack deliberately got himself arrested and shipped off to Australia to escape the Vampire King. They could be damn good allies and Jack would want to know all about his line of work.
