I dont remember where it was confirmed that namine definatley doesnt have a heart. We didnt even know roxas had a heart at first. Maybe its a very fractured one. Im just putting that out there... Maybe it was confirmed but i dont remember when it was xP
But... it was confirmed that one needs a heart to use a keyblade...
Roxas can because Sora can. His heart is irrelevant.
... No, if Roxas didn't have Ven's heart, then Roxas would be unable to wield one. It isn't because he's Sora's Nobody.
And you don't have to spoiler, it's been implied that Roxas has a heart since 04.
I don't mean to sound like an ass or anything, but you sound like an ass when you say that.
Nomura keeps implying that it's Ven's heart, but CoM says its Sora's heart.
Not really. Vexen said that Twilight Town was tied to "the other side of [Sora's] heart", but CoM never went over Roxas.
Terra was NEVER a master!
Uh... lulz, yes he was. He wasn't one in [B]title[/B], but that doesn't mean that he wasn't one. It's like winning an award and having it held from you.
And that is still considered a spoiler. It will be a spoiler until a couple of months after the release, and then it is still expected for it to be in spoilers. Stop telling people not to spoiler things when you don't know what you need to spoiler.
