This week on the Round Table, Izzie and Alex come through for their patients, Derek needs some time, Miranda learns what Cristina's up to, and George likens himself to a farm animal ...

Is George the pig?

McCritic: The man acts a lot more like a chicken, often with his head (or hair, at least) cut off. It doesn't seem like he has the backbone - or hooves - necessary to commit to Callie like a well-trained porker should.

AwayWithMerDer: No way. George is still the chicken. When Callie told George to stop chasing her unless he's ready to catch her, what did George do? Eggs.

iheartizzie: I defer to the devoted readers of Grey's Anatomy Insider to answer this for me, and so far, it's not even close. As of this posting, fans believe by a significant margin that Dr. O'Malley is not oinking material.

Married-to-McDreamy: No, George is unfortunately not the pig. For someone claiming to be ready for committment, George couldn't even muster the chutzpah to give a particularly convincing or heartfelt speech about it. His explanation of this somewhat odd but endearing metaphor came out garbled and convoluted, much like his feelings about Callie. When Callie told him that he'd better be ready to catch her if he plans on continuing to chase her, the look in George's eyes did not scream out committment to me. His decision to walk away, rather than respond, also does not bode well...

More surprising clutch performance: Alex ditching Mark and saving the day in Addison's surgery, or Izzie coaxing the burn patient into a psychiatric evaluation?

iheartizzie: Isobel. She's been on shaky ground even since Denny died, and I wasn't sure how her first day back would turn out. Izzie risked getting burned (so to speak) when she outed Gretchen, but it ended up being a great call.

AwayWithMerDer: I'm going to have to go with Alex. Izzie already had something to prove. Alex? Alex has just really been stepping up these last few episodes.

Married-to-McDreamy: I'd say the more surprising clutch performance was Izzie coaxing the burn patient. I think we've all seen Alex's admiration for the "gynie squad" growing over the past couple of episodes and it did not come as a surprise to me that he chose to hang up McSteamy's phone and scrub in on an interesting surgery with Dr. Montgomery. Izzie, on the other hand, surprised me when she was able to break the rules (again) and not only get away with it this time, but succeed in saving a patient from further injury.

McCritic: Karev, by technical knockout. Alex using the rope-a-dope strategy against Addison the entire time wasn't expected. The intern let women pummel him with their privates, pretending to be defenseless and indifferent, while actually soaking up knowledge and using it when it mattered most. Mark never saw Alex's womb walloping coming.

What will Miranda do after discovering Cristina altering the OR board?

AwayWithMerDer: Honestly, I'm quivering in my boots just thinking about it. We've been seeing the softer side of Miranda these last few months, but I think the Nazi is back. Cristina's going to get stuck with some pretty boring surgeries. Maybe she'll be working on some ingrown toenails with the resident podiatrist. That is, if hospitals even have podiatrists. Got me, I try to avoid real ones.

Married-to-McDreamy: The logical guess is that she will go to the Chief and explain what she's seen. My guess, however, is that she will set up an elaborate booby trap consisting of trip wire, a bucket full of water, and a banana peel right in front of the board to expose Christina in the act.

McCritic: I don't see the Nazi goose-stepping directly to the chief on this one. She needs to prove her resolve after the Denny debacle. So you know what that means, right, Cristina? Kiss those whiteboard marker privileges goodbye.

iheartizzie: Dr. Bailey is not one for letting things slide, nor is she the type to let passive-aggressive rage build up. Cristina's going to get an earful approximately four seconds into the next episode, and will probably be stripped of many surgical duties immediately thereafter.

So Derek needs some time. How much of it are we talking about?

Married-to-McDreamy: I predict Derek will take approximately one week. A trip to the woods with the other men will be all that he needs before he feels ready to return to his old ways.

McCritic: The good news for Meredith is it'll probably be less time than it takes him to do his hair every morning. The bad news? We could still be looking at four to five months in that case.

AwayWithMerDer: Long enough that we all keep watching Grey's Anatomy for another couple seasons just to see these guys together.

iheartizzie: Mid-May sounds about right.
