Hmmm, okay.

Well, the Council wouldn't have to change since they've been around forever. Murphy I would make some sort of kickass nurse type person, who is curious about the supernatural. She'd meet Harry when he was injured in battle and she looks after him. Then they would join forces to fight some sort of...undead attack. I think Michael, Ramirez, Thomas and the Alphas could all be the same, only soldiers in in Harry's regiment, rather than friends from the city/Council. Mister would be the regiment's cat and Mouse would find his way to Harry and stick with him all the time. Molly could be a rebellious girl who joins up as a nurse against her parents wishes. Morgan would be the overzealous regiment commander who hates Harry's guts.
