You should go. I can't. Because you want to stare at the monster? Alec's green eyes blaze, but with a wholly human fire now. Or because you pity me? I couldn't guess which possibility he loathes more. I fold my arms. I can't leave because the door's locked. Believe me, I would've gone hours ago if I could have. Oh. Of course. Then he looks so abashed--so boyish, and so handsome--that I almost want to laugh.
