Kairi's been kidnapped. Riku was in a literal realm on evil and darkness for a while, and has killed many nobodies and heartless, many of which greatly resemble humans. Sora has had his memories tampered with more then once, killed just like Riku, has killed himself to save someone else and was revived, and was told he's not worthy of being a master. These should have terrible affects on these kids. Are we supposed to ignore this?
