Well, he is right, the fact the Araragi is a masochist is exactly why she likes him.
But the thing about scraping the guy's blood from him was really clever, much more believable that he did that than if he just overpowered a more experienced vampire's cells.
@savetheprince in legends vampire are able to turn into animals. Two most often used are bats and wolves, so it makes sense for a vampire to turn into wolf hybrid.
Ah, an action scene with philosophical undertones, followed up with an ending artwork emphasizing breasts, the true essence of monogatari
P.S. why does hanekawa have cat ears but no obvious tail?
She doesn't have a tail because she's "possessed" by a tailless cat. That's the plot of Nekomonogatari, and the "events of golden week" alluded to during the Bakemonogatari arc.
