I thought it was a great episode, and that the acting from Laura Innes was perfect.
Note how Kerry acted when reprimanding Carter over his relapse. She was disconnected, as if she really didn’t want to fool with this right now. That’s so different from the old Kerry, who took sheer delight in being the authoritarian. Her new relationship has made her re-think herself entirely.
As a medical-type myself, I also loved the scene at the end, when the gravity of her job and her day all came down on her and she just had to take comfort in the one thing that, deep down, seemed right at the moment. Her face throughout that scene (and the whole episode) spoke volumes.
I really enjoyed Carter’s scenes with Chase, as well. I’ve enjoyed that whole plotline.
If Kerry adopts that kid whose mom died in the fire (which they were foreshadowing with a million-candlepower spotlight), however, that will be the final jump o’ the shark. Mark’s brain tumor certainly sent them careening toward the ramp.
