Nothing I didn't already know, but you know your secrets are safe with me. If someone else figures out it's you, they've gotta be cheating. [besides, any and all teasing he may do in the future about certain secrets will be done in relative privacy, like they somehow still have now.

The nice thing for Zack about having secrets, though, is that while in some cases they're easy to talk about, it's just as easy to set them aside and forget about them, especially with something else to focus on]

Sure. Your treat this time, yeah? [he says, as though he isn't going to try and get the bill before Cloud can]
