lol, I actually meant to say that you didn't have to go beyond active characters. Sorry! But it was fun to read.
Uh...who are the kids in Marina...la...?
I can't think of anyone but red Link and she hasn't met him. (She chooses nameless Allen!) Sakura if she was here, mostly out of lack of options, but she wouldn't really want to pick someone so...pure? Good? Sweet? She wouldn't want to taint her.
Itachi she has a hard time as seeing as a kid after knowing him older and because she didn't like being thought of as a kid at his age. But I guess ultimately she'd choose him. Even though that's totally weird!
Soubi has to pick a new master from someone in Marina. Who will it beeee?
