Sasword *is* a good guy. He has no idea he's a Worm. But beyond that, who knows. It would be sort of weird if Tendou dies (somewhat predictable), but I can see Drake or Kageyama dying easily. As a matter of fact, due to the fact that ZECT (and by extension, Kageyama) has been involved in some pretty shady **** and they don't seem to want to make him a full-blown villain, the only way for Kageyama to "repent" as it were, is the time-honored "heroic sacrifice". Who knows? Maybe he saves Tendou or Kagami. Or, better yet, for a real shock--Yaguruma.
