This wasn't my favourite episode. Firstly, I don't enjoy seeing the run-down moody Carol. Much as she has a right to be, I thought they emphasised the point enough and could have given her a little less screen-time this episode.
Secondly, I have really enjoyed the Mark and his father story-line through all it's stages. Although I prefer his father as a lively, energetic man it's obvious we need this part of the plot too. But I found it quite wearisome, especially in quite a low episode anyway.
However, I did enjoy Kovac's brief clash with Benton. It's good to know he's comfortable enough within the ER to defend himself against surgeons. I also liked Kerry's comforting Carol - some more proof that she is a generous and kind-spirited character, despite what others may say.
