Damn, Naruto got his ass whupped there. Once he goes all kyuubi, things MIGHT even out, but this is Lv. 1 Sasuke at the moment (I'm guessing releasing Orochi's seal lets him go to Lv. 2), so I doubt it.
I wonder what the "secret" of Sasuke's past is? I thought we already knew all of it...? I'm guessing Ch. 220 is just gonna be him bitching about Itachi and how he needs power and blahblahblah.
EDIT: After re-reading the topic, I noticed that someone speculated that 220 might deal with why Itachi did what he did. We already know that. IIRC, it was because he just wanted to see if he could.
