Hi! I'm Brandi and I play Dean Winchester (Supernatural) and Alec (Dark Angel). Welcome to the game! :]
Dean would probably be suspicious of Claire's ability and be all 'wtf?!?'.
Alec, on the other hand, would think that was a SWEET addition to the standard and would wonder why the heck, out of everything he was genetically engineered to have, they didn't give him something that awesome. And there would undoubtedly be pick up lines, as Alec loves the ladies. :/
