You know, I think I must have seen it back when it aired, but I still don't remember and it definitely sounds like something I'd enjoy watching again. I need to do some more looking around for older ER episodes. Last night I got impatient and ended up spending $3 to buy the episode I wanted from iTunes. It was worth it for that ep but that kind of thing could add up quickly.

Seasons 6 and 7 have some great Carter stories! The episode I watched last night has him getting stabbed and after that he ends up addicted to painkillers and there is rehab and emotionality etc. Also I hadn't realized until I went back how slashy he and Benton were!
