Here's something else I realized concerning questions that should be answered in BBS v2. Xemnas has the entire Organization running ragged looking for the Room of Sleep to be led to the Room of Awakening in Castle Oblivion - he's looking for something in there. It can only be assumed it's Ven. (Although Xemnas's line of "So, sleep has taken you yet again." is a bit confusing in this aspect - I keep thinking he's referring to Ven, but could he also refer to Sora?)
But logically, that's all impossible for him to know: Only Aqua knows that Ven is in there. On top of that, Aqua should be the only one that knows Ven is even in Castle Oblivion, because only Aqua was given the information needed to turn the destroyed Land of Departure into Castle Oblivion. So how did Xemnas manage to gain this information? Did Master Xehanort know that the LoD could be turned into Castle Oblivion? But even then, he wouldn't know that Ven is in the Room of Awakening.
