I think Reece (the Littlest Werewolf) should crush on Elsa. It would unnerve her to no end, and Harry too -- but then some of Jean-Claude or Asher (or Dumbledore) might rub off on Harry and he might decide to use this as a way to manipulate Elsa.

By the way, good on you for spotting what a manipulative bastard Dumbledore was in canon, long before most of us would admit it.
