I'm dying to see Tobi do something, but at the same time I'd hate to think Deidara blew himself up and couldn't hit either target (come on, you know he was annoyed by Tobi.) What a dilemma.

I thought this was the best fight of the whole series, except for Sasuke foiling every one of Deidara's attacks over and over. Dei should have learned the secrets of the sharingan in his battle with Itachi, given his one-eye-closed defense to it. But then, Sasuke may have pushed his bloodline to its limits, moreso than Itachi, and at this point, it looks to me Sasuke clearly outclasses his brother.
