The end of the Secret Episode, after that heartless boss battle, we suddenly find Aqua in what appears to be a dark variant of Castle of Dreams, followed by clips of of various scenes in previous games, and ending with Xehanort (and then into his other selves) at Destiny Islands, before getting the closing message of Reconnect: Birth By Sleep Volume 2. I saw that was just..... WHAT. THERE'S A VOLUME TWO?!
