Grey Departure

There's been a lot of drama on Grey's Anatomy, and we're not talking about in the scripts. On set, it would seem people are just not happy. We all know that Hiegel's a friggin' sourpuss and grumpy witch... but apparently her best pal ain't happy either:

Seattle Grace is about to lose another doctor. Grey’s Anatomy star T.R. Knight, who has played lovable intern George O’Malley since the show’s debut, has asked producers to write him off the hit medical drama. While details of his exit have yet to be ironed out, a source close to the situation says that it seems likely Knight’s request will be granted and he will be released from his contract. Recent reports that Knight has not been attending table-reads for upcoming episodes or that he had walked off the set and cleaned out his dressing room are inaccurate, a rep for Knight tells PEOPLE: “He has been there every day. He was at a table read yesterday. He hasn’t said goodbye to anyone.” The rep had no further comment on his possible exit....So why does Knight, who remains a fan favorite, want to leave? “Have you seen the show lately?” says the source. Knight has received little screen time this season, with the show focusing on controversial storylines like the romance between Katherine Heigl’s Izzie and her long-dead lover, Denny. “It’s time to move on,” says the source. “It just feels like this is the right time to go.” [people]
