I went to KH13.com and one of the information said it like this: - Lea (Axel) and Sia (Saix) appear as children. They are speaking with Ven (in what looks like Radiant Garden?) They look to be about the same age. Axel looks similar to Hayner and is wearing a scarf-like thing. Saix is wearing clothes that have a moon symbol on them. Lea: “It’s because we’re friends. Got it memorized?” thats probably the name of Saix's orginal self. --Cococrash11 18:16, December 19, 2009 (UTC)Cococrash11

maggosh Strike backwards... "That's a nice expression."

You're terrified, aren't you?

But it's not confirmed.

Heh, even as children, Axel was saying his catchphrase.

But yeah, it isn't comfirmed yet. Like Maggosh said.
