This week on the Round Table, Izzie bakes, Callie gets down (and George gets jealous), and Mark makes a McSteamy return. Our esteemed panel weighs in on last night's episode...

Should "I Am a Tree" have been the season premiere, as Canadian viewers mistakenly believed it to be?

McCritic: Yes. Little was accomplished in the actual season premiere that couldn't have been condensed and fit into this entertaining episode.

AwayWithMerDer: Since the U.S. season premiere had useless flashbacks and no real plot, I think Canadians got it right. I don't see why they're complaining they got to miss our boring season opener.

Married-to-McDreamy: Definitely not. Had "I Am a Tree" been the premiere, we would have missed watching Meredith struggle with her decision over which of her male courters to choose. Oh wait. That's still happening.

iheartizzie: The actual premiere wasn't all bad, but last night was far superior, a return to the Grey's Anatomy we love. Sandra Oh's native land may gripe, but they actually made out great with this supposed gaffe. To borrow a classic Napoleon Dynamite quote: "Luck-y!"

Jealous George: Sweet and adorable or overbearing and frightening?

iheartizzie: Watching George act jealous and insecure is hilarious. How can you not love a guy who uncomfortably asks his female friends about panties, or who flirts with girls and almost punctures their eyes with darts in the process? Bambi is sensitive and often overwhelmed by life... which is why we love him.

Married-to-McDreamy: I don't think I could ever refer to George as frightening. I find Jealous George endearing and cute, although the scene in which he's throwing darts at the nurse's head baffles me. Was that an attempt to flirt with her? If so, he may need some tips from a certain colleague, who was shagging the patient in the bathroom.

AwayWithMerDer: Yeah, I'm going to go with frightening. He simply does NOT have the dart skills to be jealous.

McCritic: George was just curious. While that may unnerve men in yellow hats, Callie was right in taking it as a compliment. It may take random panty discoveries to elicit deeper emotion from the cuddly intern, but at least it's there. The same can't be said for Callie's pants when she dances.

Should Izzie forego a medical comeback in lieu of becoming a baker?

AwayWithMerDer: Definitely. I can't wait to watch the episode where Izzie falls in love with a muffin.

Married-to-McDreamy: Despite the fact that Izzie is apparently an excellent baker, she definitely looks much cuter in scrubs than in an apron.

McCritic: Undoubtedly. Not because she's partially responsible for killing both Denny and the man who was supposed to receive the heart in last year's season finale, but due to the joy her muffins can bring. You might recover and save a life or two in the operating room, Izz, but there are plenty of doctors out there. The world needs more sweet, moist muffin makers. STAT!

iheartizzie: Yes. Did you see the volume of baked goods this girl cranked out in the span of a day? Imagine of someone were paying her for them! The muffins seemed to be well-received by Addison, too... although everything tastes better when drunk.

4. What will happen with Addison and McSteamy?

Married-to-McDreamy: One can only hope that he will continue to walk around on the show in just a towel!

McCritic: It's hard to say. But hopefully Mark won't be wearing any more clothing than he was last night as it keeps happening. I'm hoping for a Towel Off or two in the future with McDreamy.

AwayWithMerDer: Since Addison apparently waited all of one day after the dissolution of her marriage to call McSteamy -- and he managed to arrive, from New York, on that day -- I'm guessing this is more than a booty call. Now, where will Addison and McSteamy end up? New York? Seattle? Since the show is based in the Emerald City and Addison is way too hot of a character to get rid of, I'm going with Seattle.

iheartizzie: Dr. Mark Sloan longs for Addison almost as intensely as the Insider's own McCritic pines for muffins. So you can bet this stud-muffin is going to try and win her back. Hopefully Richard can get this plastic surgeon a job at Seattle Grace and elevate staff awkwardness to even greater heights.
