When pigs fly: Major Owen Hunt (Kevin McKidd) joined the staff of Seattle Grace as the new head of trauma for the hospital. He immediately shook up Cristina, whom he'd kissed in an earlier episode, by not remembering her name. He angered Derek and Mark by having Alex apply the equivalent of a field dressing (skin glue) rather than call them in to help with a head injury. He outraged Izzie by stabbing four enormous (sedated) pigs in order to teach the hospital's docs how to respond to trauma as he'd had to in Iraq. (ABC flashed repeated warnings that no animals were harmed, but we're still wondering what PETA will have to say about this.)
By episode's end, though, Hunt had charmed everyone. He contritely told Derek and Mark he'd listen to and learn from them. He'd listened to Izzie's spiel about how modern doctors can use technology instead of animals to learn new procedures. And he'd confessed to Cristina that he was the lone survivor of his Iraq unit. "Before ... I knew your name," he said in a touching speech. "And now I'm living in the after."
She's no Malibu Barbie: Meredith found an old plaything, Anatomy Jane, a doll with removable organs that she'd loved as a child. The ugly doll helped her come up with a way to treat a 10-year-old girl with a seemingly inoperable tumor, but it shook up the Chief. He finally confessed that remembering young Meredith with her doll forced him to face his own failures, and seeing the tumor girl's devoted family made him recall how alone Meredith has always been.
Make like a tree, and leave: Erica was over the moon about sex with Callie, comparing it to the time she got glasses and realized the green blobs on trees were really leaves. But Callie didn't have the same "aha!" moment, and kept sleeping with Mark to try and determine if sleeping with men or women was more her style. Callie finally confessed her dalliance to Erica, but then headed out for a drink with Mark, claiming they could still be friends. Remember when Callie first joined the show and she seemed to be the one doctor who didn't do stupid relationship things? Yeah, that was a long time ago.
Alex and Izzie, sittin' in a tree: In perhaps the show's most boring relationship ever, Alex and Izzie fought over his asking if they were going to be exclusive or if he should continue to sleep around. Alex eventually confessed that he's "not good at relationships" (duh) and the two agreed to "go steady." And then they're going to make friendship bracelets, get one of those BEST FRIENDS necklaces that breaks in half, sign each other's yearbooks, and meet up with Archie and Jughead at the Chocklit Shoppe.
Next week, she'll heat up a can of Raviolios: Lexie was still upset that George wasn't crushing on her the way she was on him. First, she chose to ignore him. In the end, however, she made him boxed macaroni and cheese and served it by candlelight, apologizing for being "too emotional." Obviously, she is an honors graduate of the Meredith School of Martyrdom. Does anyone have Oprah's number?
Stupidest scene: Tori the Tumor Girl's father repeatedly called the Chief while he was in the middle of her complicated, life-threatening surgery. And the nurse kept interrupting to tell him! And he finally threw down his gloves and left the operation to go talk to the man! It was supposed to show the Chief how loving Tori's family was compared to how Meredith was raised, but really, it just showed that you should never seek medical care at Seattle Grace, where anyone will leave a complicated operation for just about any reason.
Best line: Cristina, trying to get out of caring for the stabbed pigs: "I'm not Dr. Dolittle!"
Second-best line: Bailey, when Izzie complains about Meredith (and Anatomy Jane) being chosen for the tumor surgery: "Next time, you'll know to bring an ugly doll, won't you, Stevens?"
