I was with Darth there when she locked the door. They made her out to be so much of an Orochimaru fan before, I expected her to go skitz and kill Sasuke for it. Heck, I even expected that alter-personality thing to be a trick to make Sasuke lower his guard.

I'm slightly disappointed that didn't happen.

I don't know about everyone else, but this episode seems to have made ninjas look incompetent at detecting others. From what I saw, those prisoners are everyday folks, not skilled ninjas of any competent prowness. You can assume they're probably not trained to hide their presence like proper academy ninjas are. Yet Sasuke had trouble trying to find them?

Orochimaru detected Naruto, Sakura and Sai from all the way across a bridge back when they rendezvoused with Kabuto.

I kind of expected more from the man who killed him.
