Na, I have the same problem with Guy. It's understandable.

I guess it's just a matter of who you want to have development with at what times. There's nothing wrong with keeping the brackets simplified or vague or even nonexistent if it's a stranger or someone Zelos doesn't really want to be open around. No need to be paranoid or anything - I think it's fine to vary it based on his relationships with people, and you're doing okay with that. :)
