Firstly, how exactly do you know that it wasn't a couple hours after, hm?
Did it take you a day or two in hours/minutes to beat the game from the point when you beat Riku to the ending of the game? If so, thats pathetic.
Xemnas named him and what not, how do you know he didn't give him his Org. XIII coat shortly after and initiate him officially later? You don't. Because if I recall, in the new screen of 358/2, Roxas had his coat when being initiated.
Because Xemnas didnt just 'hang' around with Roxas after he named him, he most likely left to do some stuff important to the Org, like trying to find out how to for KH.
Do you think that Xemnas talked to Roxas directly after initiating him? Um, no, that wouldnt happen. Xemnas probably sent Roxas to prove himself to the other Org members to show how useful Roxas was going to be. And, Roxas would have to be fairly well with weilding a keyblade, because(look below)
I'm gonna agree with VAT and say you should stop acting like you know everything.
Shes only saying that cuz she knows more than i do, and she knows it.
Because there is no way to tell all these timespans you say you know.
I dont know. Im trying to figure it out by arguing with you.
And how exactly could Xemnas have gone and seen Ven? Ven isn't around anymore. And what reason would Xemnas have for going to see him?
*Whistle* I cant give you a difinitive answer on this, except that Xemnas must have known something about keyblades, and something about Aqua
He had a reason to go see Sora. He needed him to collect hearts for him.
. . . . Umm, no. Xemnas didnt want to collect hearts for Sora...
