Weird poses done right, the anime.

But yeah, it was nice to watch Araragi embarrass Senjougahara. By (unfortunate) modern standards she's mainly a self-proclaimed tsundere, but she did show some stronger signs here. Not to mention Shinobu, of course, though if I call Senjougahara self-proclaimed, Shinobu should be called self-made. No doubt this display was also but a result of the weird relationship and coexistence those two have.
