i take back what i said previously haha i sounded stupid but this ending does make sense because riku doubted himself showing humility and sora had a cocky attitude before taking the exam its the same cliche that every director does with the hero hes powerful for an extremely long time and gets big headed/arrogant but when it matters he loses and has to do something great to level his ego and get back on the same page as everyone else but when he does come back its with a power no one can even match its a cliche im a sora fan 100% through so i hope this ending isnt true but the way all the trailers are showing sora and the past games leading up to this are showing it seems as though sora will be the terra and riku will be the aqua
