The first scene was awesome. Although I'm not sure how much it would help Araragi's recuperation to have all his blood accumulate to a place that has little to do with healing wounds... Anyway, I reckon Senjougahara is simply a realist and thus wasn't apparently overly worried about Araragi, knowing he would heal. Of course there might have been some shock and masked concern involved as well.

Kanbaru turned out to be a pretty funny girl. Even if she didn't have a monkey arm but a demonic arm.
