I really enjoyed this one. The characters felt their age and acted realistically given their backgrounds. James (at first) acting like Kurt should just get over his parents' rejection made sense given how his own family behaved. And it was so sweet when he was trying not to push for sex, but he really, really wanted to.
Kurt also acted fairly realistically given his very recent experiences, but I didn't enjoy him quite as much. I have a low angst tolerance, and he was awfully pathetic. I would have liked to see him again later when he had more self-confidence back (we do get a bit of that).
