i have watched and watched this cutscene over and over with Xemnas walking by Roxas in the realm of darkness to tell him his true name it Sora or Ventus that he says because for those who have seen bbs terra/ xehanort (could never spell his name right) knows ven, who technically is roxas, so any ideas.

He doesnt know that Roxas has Vens heart, but I am sure he remembered Ven when he first saw Roxas. Maybe thats why he started looking for the Chamber of Waking. Maybe the sight of Roxas made him remember things about his past.

If you look into a further cutscene, it replays that part and Xemnas says Sora. But it isnt available in the cutscene list.

Xemnas called him Sora. It reveals this in a later cutscene.

In later cutscenes you can see that Xemnas says to Roxas, "Sora"

I don't think so, Xemnas started to work with Castle Oblivion before Roxas joins.

Remember in a cutscene with Xigbar and Zexion, Xigbar says something about that they have just started to work with Castle Oblivion and also mentions that some guy named Marly or something (Referring to Marluxia) has just joined.

Xemnas says Sora on like day 299 or 300....I dunno somewhere about there.

VEn is not roxas and when xemnas told him his real name he meant sora Xemnas was the one that gave roxas his new name hoping to use him for his own purpose and also he recognized roxas face the minute they had met he look exactly like the keyblade master Ventus.

well i started thinking Ventus when Xion basically was shown as Ventus when she was fighting Xigbar, and since then have wondered if Xemnas knew that Roxas is Ventus from bbs, which is how i got to that conclusion

 

then in another cutscene where Roxas is on Destiny Islands and he sees "Xion", is Zexion talking about Ventus when he talks about going to other worlds before you came to this world"

He says Sora. You find that out later.

You know, when you finish the game, you'll find out.

No, he was referring to Riku. The dialogue in that dream sequence was exactly the same as Riku and Zexion's conversation in Castle Oblivion, on the Destiny Islands floor.
