That's possible. Aqua could also mistaken Roxas for Ventus.
When Sora somehow manages to get Aqua out of the Realm of Darkness, (Which lets be honest that's probably going to happen in KH3, same for saving Terra and awakening Ventus) I would like to see Aqua's face, like "I remember you, you're that boy... From the Island" Or whatever :P
(Sorry for the bump) In 1.5 they remade all of the music, gave KH 1 the ability to control the screen with the right analog, and it's FINAL MIX in English! (Finally) I hope in the 2.5 Remix they make BBS playable, that would be amazing.
Thanks, and yeah, so far (to how the teaser of KH 3 looks) The graphics look amazing. (Not that that's all I care about) But lets be honest, we need to hop off the DS's and PS2s. I seriously hope they make KH3 for PS3 because I don't see myself owning a PS4 for the next 10 years. :P
(Hello, I am new :P) Anyways, I think that they're going to release 2.5 HD Remix before KH 3 so that it will be: KH 1.5 KH 2.5 KH 3 Although they announced KH 3 first, I don't see it coming until late 2014/Early 2015.
