Whichever secrets come to mind. I could see them maybe doing something with that obstacle course and him being all, "Hey... I'm actually Richie, too," if that works, since I think he knows Kitty is Shadowcat. She really doesn't keep up the secret identity thing as strictly in Marina. Though, the gay thing might come up if she tries to kiss him. ^^; She may be in a kissing mood with the guys she thinks are cute.
That is true. They are. Though, technically, Touma's pretty buff. Anime artists drew guys a little more muscular in the 80's/90's than they do today. Duo and Tieria are definitely more slender in their art style than the YST guys. Their sense of style, on the otherhand...
Duo would be more than willing to get Rapunzel to do anything, since, well, he's up for doing anything thanks to the event. This could be interesting~.
