I'm not yelling at you! [No, wait, that's wrong. He quickly backtracks:] Well, maybe I am, but I'm not yelling at you for getting injured! I can just about deal with you getting injured, it's the fact that you didn't tell anyone that I'm yelling at you for!

[He turns around to face her, and runs a hand through his hair again, wide-eyed.] What if you'd got really badly hurt? What then?
