Ugh, no, that would be a continuity nightmare.

(the gm having to back and edit I mean!)

Edit: Posted, didn't have to change to much as it turns out. Made it more a matter of occupying the werewolf while the others can regroup and kill it for him. Henry doesn't have as much 'power' as the others when without his violin. He tottaly stabbed a werewolf with a silver fork!
