Poor, poor, poor Hanekawa. Maybe it hit the harder because I've known a girl working at a shelter for kids. You have no idea how true Hanekawa's dialogue regarding her foster parents sounded.
Great episode though, it's interesting to see Araragi's relationship with the class rep. He's really regarding her as a friend, I'd say she's the one person he's relying on, besides Hoshino. It's going to be interesting...
