Part of what is impressive about it is that it is a double episode in which everything pays off. George's lesbionic fantasy of showering with his female housemates gets echoed by the scene towards the end when he sees Izzie and Christina washing the dead bombsquad man out of Meredith's hair and knows he shouldn't be there, and retreats. Christina Ricci is fabulous as the paramedic who eventually cracks and runs away, and there is the weasel anaesthetist and his talk of Pink Mist. (Don't ask.)
Just extraordinary. And no, I don't entirely know why I am watching Season Two on terrestrial and Season Three on downloads and just living with two different phases of these people's lives. I am developing a pronounced taste for a show I was always meh! about and which I started to watch just so I could read my friends' femslash for it. Go, as they say, figure.
