I don't really have much to say about this episode. The whole time I was watching it, I had basically no real reaction one way or the other. It was perfectly watchable but nothing too outstanding. There were two plot threads I found myself caring about the most this week:
The first was Owen and Christina. I thought that the story this week was a pretty compelling way to add some conflict into their professional/personal relationship. The fact that Owen loses his cool because of his connection to the kid was nice, and I liked that Christina didn't put up with it. She's a good surgeon, and she knows what she's doing. Owen's connection with the boy, Ethan, was really sweet to see as well. I think this is probably a thread that will carry over into future episodes, and I'm happy to see more.
The other plot thread that I enjoyed was the one centered around Derek, Shane, and Heather Brooks. This show is pretty genius in the ways that it introduces new characters and builds them up until we hardly remember a time when they weren't here (Jackson and April, anyone? Owen too!) The intern characters are a lot of fun, and I find myself really invested in their story-lines. Shane was getting jealous of Derek's attention to Brooks. It was a fun plot thread to follow, and I found myself rooting for Brooks while at the same time a bit sad that the Shane/Derek duo was losing its strength. I hope they continue with this in the future.
