Zelos is the type that normally would piss me off, but I think it's because of how the rest of the party treats him that what otherwise would be annoying is endearing.

I really hope Zelos is in the top three for me this time, if not the top, because there's supposed to be a special scene at Altessa's if he's the favorite. If not, I'll probably pick a Tethe'alla character, because they need all the relationship boost they can get, and turning away the Sylvarant people will lower their affection for next playthrough. Otherwise, I'd probably pick Genis, because one of the guides says that an interesting thing goes on with his voice when he's kidnapped.
