That's what i mean, Sasuke didn't end them with one CT because he can't, he needs help.
These guys obviously have a way to hide their chakra, if they didn't then Naruto would have found them and fodderblitzed them by now. Also, Naruto was obviously holding back on Bolt, unleashing his full speed on a few kids would be overkill and he might accidentally seriously injure them. Also, how do we know the fox doesn't know?
Okay, so if Sasuke is so capable of handling the situation, he wouldn't have to bug Naruto to tag along, he could go to Orochimaru himself and get help, why bug a Hokage if its a matter he can handle alone? Obviously there's something which Naruto is required for. Sasuke isn't stupid, he won't call for his friend to help him for shits and giggles.
1. Right because being logical = being biased, fantastic logic!
2. Okay, so tell me this, if these villains are meant for the kids, why is Sasuke calling Naruto to come help him? If he's perfectly capable of handling them, he wouldn't have to bug the Hokage. Obviously Sasuke needs Naruto for something.
