Kingdom Hearts II Secret ending II analysis

I just got KH: COm today and it's totally cool!....then it hit me, try and connect memory of xehanorth and birth by sleep....if you can remeber the first time you'll go inside castle oblivion there is a phrase (i kinds forgot sorry) but it's something about forgive and remember, and if you start to remember, your other memories will awake, what if xemnas has also faced this, that he forgot and remebered, that his memories awoke from slumber....or something like that

 

Well,what I have found,one of the people in armor has to be related to Sora because I found a picture of him with his helmet cracked and you could see part of his face.
Its going to be in my profile.
