So I was rewatching Theater Mode for DDD and I was a little confused on something. I know that Xehanort's heartless was in Destiny Islands during KH1 and because of that he was able to appear at the beginning of the game and put the Recusant's Sigil on Sora. But how did Xehanort/Ansem SoD know to go to Destiny Islands the night it fell to darkness? When YX is taking Sora through memories towards the end of the game Sora asks the same question and YX just says "Simple" and then the next memory in Traverse Town starts without answering the question. Thoughts?
