Re: The Official VA Discussion Thread - Home of David Tennant & Drake Bell Speculation!
we dont know why alyson was chosing over hayden it could your reason or the maybe alyson is just fulling his contract with 0.2 and 3 since since 0.2 was going be a part og 3 it all just specultionIt was such a small line ("Hey Axel") so I'd hope that they were recording Alyson early on just for Xion (it goes against the characters having the same voices, but having both voice actresses honours their commitment to the series) and they knew that an upcoming trailer needed Kairi to speak so they had her quickly record that.
But the more likely event is that Kairi is voiced by Alyson and they just rudely tossed Hayden to the side.
