We all know that Seph was an optional boss in KH1 (not to mention INSANELY difficult to defeat), and it turns out he's back in Kh2. But it seems he's actually gonna play a valid role in the story, I just don't know what exactly. All I know is that Cloud runs into him @ Hollow Bastion (judging what I saw in the scans). If anyone can shed this light on this mystery, I'd appreciate it.
