Owen has a present for Cristina. That being Teddy Atlman. Teddy is a cardio god. Or goddess. Yang is not Yang if she is easily pleased, so she wants to know things about Teddy and why she hasn't heard of her.
At first, Teddy is just adjusting a bit from spending so much time in Iraq, but Cristina takes that to mean she doesn't know what she's doing at all.
Eventually, Cristina ends up liking Teddy a lot because she let her do some highly risky and difficult procedure. She's a really good teacher, too.
Don't judge a book by its cover.
However, her relationship with Owen is intriguing. She's not an ex, but she has a thing for Owen, she reveals. It's interesting to see where this goes.
Elsewhere, Adele sort of accuses Bailey of having an affair with the Chief simply because the latter didn't go home. She's not, but something is up with Richard.
In the end, Bailey conceded that the Chief can indeed be her work-husband. After the Chief decided to take a break from his surgical duties, Bailey takes over for him.
But what is wrong with this guy? He botched a surgery and Bailey had to redo it. Later, we find out.
Oh yeah, Izzie is back at Seattle Grace. She was living with her mom in Chehalis, and only showed up because her high school teacher and mentor, Dr. Singer, had a problem remembering ... anything.
That case was great to watch - they figured out that he had fluid blocking his brain from receiving ... well, something. You gotta love Derek, though, and Izzie telling the Chief to do the surgery or else.
The first time Alex saw her, it was heartbreaking, his expression saying, "What the hell, Izzie," a combination of sad and mad.
They weren't talking at first, and when they finally did, Izzie started blaming Karev for getting her fired, which is did not sit well with him.
Alex says she didn't give him the benefit of the doubt, made a conclusion, and just went away. He can't forgive her either, he says.
The Chief, finally, concedes that he's exhausted, hands over all his surgeries to Bailey, after botching an otherwise routine surgery.
There's a Chief montage while he's drinking, and he really does appear under the influence. Poor guy.
