(S06E16) I don't understand why it took 'Grey's Anatomy' fifteen minutes to run the credits on the bottom of the screen. They even included Katherine Heigl's name, and she didn't show up in the episode. How does that woman still get top billing? It's great that Izzie wasn't around, she would have been one too many. Luckily, the two mousy women weren't around in this episode. Do all four Mercy Westers ever show up together anymore?

I have a feeling that this week the writers took a step backwards. There were a lot of funny moments, mostly led by Cristina, but some of the plotline wasn't the strongest. The patients of the week didn't steer the doctors in any direction like previous weeks. Instead, the three patients followed the title, and one little accident changed their lives for the better.

After trying to help Bailey out with a date, Arizona turns to the next available person: Teddy. I could understand why people wouldn't like Arizona, but she brings a light quality to a usually depressing show. I appreciated that they referred to Holidaze and Owen playing the guitar at the Christmas party. Any time the writers include lines like that, I feel like they are actually attempting a cohesive storyline. Then the writers have to destroy a perfectly good storyline: Arizona mentoring Alex. He had all the potential to be a good pediatric doctor, then Arizona tosses that because Alex had sex with Callie years ago before Arizona was even around? That's quite immature for someone who saw the potential of Alex as a doctor.

Cristina goes rogue after Lexie suggests a very complicated lung transplant. Somehow Teddy is roped in, but is upset that people are driven by paperweight awards. Knowing Cristina, if she overheard the conversation with Lexie, and Harper Avery wasn't around, she still would have done the surgery. The surgery did save their patient. Ironically, you know that this surgery will probably not be awarded some Harper Avery Award, even though it was harder -- or that Teddy will not accept the award.

We find out that Jackson, like Meredith, came from a legacy of famous surgeons. Unlike Meredith, Jackson had the opportunity to learn from his grandfather, Harper, but wanted to be his own man. The thought was respectable, being stuck in the shadow of your forefathers, but he learned that he should still sit down and learn from his grandfather. I found it great that the hubris of Dr. Harper Avery caused his downfall. If he was treated like a normal patient and went under, there would have been no complications.

Speaking of legacy, I'm really disappointed with Dr. Webber. In all reality, this high ranking guy could go to another hospital and succeed. Instead, he sticks himself back into Seattle Grace and makes a fool of himself, trying to prove his worth to Dr. Avery Sr. He should just move on or switch to doing research and let Derek lead the hospital.

Callie had to balance a mother with a broken leg and trying to hold back Mark. I like having Callie become the voice of reason for Mark, but it's almost a shame that he didn't need her while Lexie was around. Now that he's single again, Callie has to revert back to trying to get him to grow up again. It makes me wonder how Callie would have done as the Chief of Surgery, because she has been more firm with Mark than Derek has ever been.

As for the minor nuances, the lung that was created was surprisingly believable, or at least really cool to see over a big glass dome. With Lexie having blond hair, she looks closer to being a believable half-sister to Meredith. This episode was really "let's be mean to Alex day," wasn't it? After Izzie left, he doesn't catch any breaks anymore. I like seeing how the baseball field has become that alternate to the show stereotypically ending in the bar, Meredith's house, or the elevator; though let's hope it doesn't get over-abused. Finally, kudos to the writer who had Christina taking a picture of her with Dr. Avery Sr. on her phone.

While we didn't see enough of Bailey in this episode, it looks like she'll be around a lot for the next episode. How did you like the episode? Leave comments below.
