Yeah that was me and I'm pretty sure it was Yamato especially since Tsunade and Shizune were waiting for him and he showed up late without a reason and she just shrugged it off indicating that she might have actually sent him to spy on Sai or he might have just done it on his own. Naruto is still a kid with an obsession he just believes now for some reason that he has gotten so much better because of his training with Jiraiya but as we've all seen he hasn't and he definitely has a rude awakening coming his way.
