TR Knight and Katherine Heigl were the Bonnie and Clyde of Grey’s Anatomy. Or the Fred and Rose West. We can never decide which.

TR Knight and Katherine Heigl did everything together – they got their Grey’s Anatomy co-stars fired together, they relentlessly bitched about what a chore Grey’s Anatomy was together, and now they’re both leaving together, according to co-star James Pickens, Jr.

What of TR Knight and Katherine Heigl post-Grey’s Anatomy? Well – since one’s a gay man and the other is an impossibly hard to like woman – maybe a Will & Grace-style sitcom about, let’s say, two failed actors.

We have to say, we’re worried about Grey’s Anatomy. Over the last few years it’s become all about the staggering egos of the cast and crew, which is heartbreaking. Everyone knows that Grey’s Anatomy should be all about piss-weak soap opera storylines, pointlessly vague voiceovers and more soggy-knickered mimsying indie music than anyone would ever actively wish to listen to.

But the good news is that the constant ego-driven wankery of Grey’s Anatomy might be over, because its chief proponents – TR Knight and Katherine Heigl are on their way out. MSNBC reports:

James Pickens, Jr., who plays chief of surgery Dr. Richard Webber at fictional Seattle Grace Hospital, told Us Weekly that Katherine Heigl and T.R. Knight are on their way out. Us also quoted a set source as saying “(Knight) complains to Katherine all the time. The energy on set will be much better when he’s gone.”

Oh, don’t look so surprised – both TR Knight and Katherine Heigl have been pretty vocal about what a drag it is to work on Grey’s Anatomy – TR because his beautiful doughy face isn’t onscreen for long enough and Katherine because she doesn’t feel as if the writing on Grey’s Anatomy is as good as, say, that terrible 27 Dresses movie she made.

Will TR Knight and Katherine Heigl really be leaving Grey’s Anatomy forever? Let’s not be so sure – US Weekly also quoted a source who claimed that the Grey’s Anatomy writers want to create an ending for Knight’s character that will leave him able to return at a later date.

Meanwhile, we’re guessing, they want Katherine Heigl’s character to be dropped out of a helicopter onto a pile of infected medical waste just before a tank runs over her, reverses and runs over her again, followed by a full marching band trampling over her broken limbs playing an especially jaunty version of Ding Dong The Witch Is Dead. Just a guess, there.

But if TR Knight and Katherine Heigl do leave Grey’s Anatomy, it doesn’t leave the show in great shape. TR Knight will have gone, Katherine Heigl will have gone, Isaiah Washington is long gone, that lesbian doctor woman has left and that other lesbian doctor woman has left as well. And with Patrick Dempsey contractually obliged to appear in every fifth romantic comedy ever made, that essentially makes Grey’s Anatomy nothing more than a show all about that irritating woman who looks like a malnourished upturned eraser-tipped pencil. Who’d want to put themselves through a tragic ordeal like watching that?

As everybody knows, although onscreen Grey’s Anatomy can be almost fatally tedious, off-screen Grey’s Anatomy is brilliant.

You want a comparison? OK. Onscreen, the latest episode of Grey’s Anatomy revolved around a bunch of doctors wondering who’d be asked to perform some surgery on a patient. For approximately the billionth time.

But off-screen? Off-screen the latest episode of Grey’s Anatomy revolved around dollop-faced actor TR Knight throwing the mother of all strops and walking off the show because nobody’s giving him the attention that he obviously deserves. See – which one would you watch? Oh, neither? Actually, us too.

We’d love to be a fly on the wall behind the scenes of Grey’s Anatomy. That’s mostly because we’d love to vomit on everyone’s lunch and give them all food poisoning, but because it’d allow us to see the extent of the rumours that the actors all hate the writers, the producers all hate the actors and the actors all hate each other.

It certainly seems that way, what with actors fighting, actors screaming homophobic slurs at each other, actors turning down awards because they thought their scripts were terrible and producers firing actors because everything was getting a bit gay. And now, the cherry on the cake – there’s been a Grey’s Anatomy walk-off.

TR Knight – who plays, um, someone on Grey’s Anatomy - has apparently decided to leave the show because producers refused to change the title of the show to The TR Knight Medicine And Meaningful Looks Hour, change all the characters’ names to ‘TR Knight’ and make everyone walk around the hospital in TR Knight masks singing a song of TR Knight’s composition entitled Ooh Yeah TR Knight Is So Flipping Great. Or, you know, something. People reports:

Why does Knight, who remains a fan favorite, want to leave? “Have you seen the show lately?” says a 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.

We can’t help feeling that TR Knight is acting like a little bit of a petulant brat here. After all, Grey’s Anatomy is an ensemble show, and sometimes everyone can come to the forefront with a storyline about hardcore necrophilia. It happened with Cheers and it’s damn well going to happen with Grey’s Anatomy.

But still, you can see why TR Knight is so keen to quit Grey’s Anatomy – stars like Sandra Oh and Katherine Heigl and Patrick Dempsey have long since started to make the transition to movies, and there’s little doubt that TR Knight wants to follow suit.

True, he’ll have to wait until someone writes a movie script about a tubby-faced Little Lord Fauntleroy who looks like he’s about 12 years old, and then cross his fingers and pray that the director’s top 35 choices for the role all turn it down. But that day will come, we’re sure of it.
