Xehanort with namine's work???????????????? Namine was born when Kairi's Heart inside Sora's. How can Namine do something with xehanort's heart and memories(long before she was exisT)??
i think there is a mixed memory when sora sleeps there. because if ven used it maybe his memories mixed with roxas. but after roxas combined with sora ven regain his true memories
Based on my opinion may be Ven is the one who use the sleep pod, because at the BBS trailer he asked aqua to erase him(maybe it means to erase his memories).
