Last week on Grey’s Anatomy, Derek Shepherd stepped into the spotlight, saving a co-worker’s legs and life. This week, Arizona Robbins (Jessica Capshaw) steps into it, testing her ethics while trying to save a patient — a 10-year-old whose parents have millions to donate to the hospital. Could Arizona bring Seattle Grace out of economic turmoil? Capshaw tells TVGuide.com about the challenges her character will face, the upcoming speed bumps for Arizona and Callie (Sara Ramirez) and the possibility for wedding bells at Seattle Grace…

TVGuide.com: What can you tell us about the Arizona-centric episode?
I have a patient who I fight very hard for. Everybody feels strongly about it and it’s a very high-stakes episode. It’s life or death. The episode speaks to the whole idea that money runs a hospital. The chief [James Pickens Jr.] is having a hard time figuring out how to make the hospital ascend the ranks of the numbers game, [and] money helps make that happen. Arizona’s case happens to be with a set of parents who have the ability to give or not give in a very consequential way.

TVGuide.com: Arizona seems to have a pretty straight moral compass. How will she feel in making these decisions based on money?
Yeah, she’s a little perfect that way [Laughs]. This episode has all of that in mind, but at the same time, we are all only human and we can all only ever do the best that we can. Sometimes the best we can, in her case, leaves her a little more vulnerable to the elements and to the story and what’s happening. She has to make choices that are very hard as a surgeon, but also as a pre-eminent doctor in a hospital that is part of the reason that people are giving money or not giving money.

TVGuide.com: This episode also features Arizona’s birthday.
She has a birthday and very in line with Arizona’s character, who is not about herself and just very clear about who she is, she’s not the one to be asking for balloons and candles. She thinks it’s a day like any other day. There is a party, but it’s not one that she knows about. Given that in this particular episode we’ve centered on her professional and personal life, the two definitely crossover. She doesn’t have the typical reaction to someone going out of their way to throw them a big party.

TVGuide.com: What’s in store for the future of Callie and Arizona’s relationship?
This season has been about cementing a very mature and grounded relationship and taking it forward. This is a drama, of course; there will be conflict, but for the time being, they’re enjoying being in a relationship that seems stable.

TVGuide.com: We have not seen Callie and Arizona get intimate this season. Sara Ramirez said they probably are. What’s your take on that?
Definitely, of course it’s happening. They’re in a committed relationship. It’s like the beginnings of any relationship, but I think they’re very much together and all of that is happening. I’m sure that we’ll have our time.

TVGuide.com: Callie has vacillated about her sexuality. Could that be an issue that comes up?
There’s definitely ample opportunity for that to happen. Obviously the halls of Seattle Grace have been well known for missteps. These are doctors, they’re in intense situations and their personal lives follow suit. They make mistakes. They kiss the wrong people, they sleep with the wrong people, they sleep with the right people, they kiss the right people. We get to see how things unfold and if there’s forgiveness. Callie could find another guy or girl. Her playing field is vast.

TVGuide.com: Will Sloane (Eric Dane) and Arizona butt heads because they’ve slept with the same woman?
In a way it’s implied that they might. Whenever there’s been a chance to play that I am intimidated by him or being standoffish, I’ve always chosen to make it very playful. It’s much more Arizona’s style to find it very amusing.

TVGuide.com: Could there be wedding bells for Callie and Arizona?
There’s probably a lot more stuff that has to happen before that happens. Listen, being that I’ve been married for five years now and I’ve been with my husband for nearly eight, you have to make sure you’re with the right person and you need the groundwork to be laid. I don’t think they’re going to get married just to get married. As Arizona goes, I think she has incredible discipline and she does, as you said, have a very strict moral compass and marriage would not be something she would jump into without giving it a great amount of thought.

TVGuide.com: Arizona refers to her family a lot. Will we meet her dad?
I hope that we do. They’ve certainly set it up that we could and it would be a great opportunity to take advantage of.

TVGuide.com: Arizona has been much less fazed by the merger. Is she just superconfident?
It’s sort of funny, she never thinks she’s wrong and you don’t hate her for it. There’s no ego though, she just always thinks she’s right and she is. Cristina wanted to get on my service because no one was going to let go of the person that saves babies, so maybe that’s part of it. In Thursday’s episode, it will be revealed whether or not she’s worth her weight in gold and how important she is.

Next week’s episode of “Grey’s Anatomy” will be born out of the creative mind of Chandra Wilson. The actress who portrays Dr. Miranda Bailey in the medical show made her directorial debut in this October 29 episode which is called “Give Peace a Chance“.

When Isaac, the hospital lab tech, has an inoperable tumor wrapped around his spine, he turns to Dr. Derek Shepherd to do the impossible. Derek tests the Chief’s authority when Richard objects to moving forward with the risky surgery.

Chandra Wilson is the first star of the show to take a role behind the lens. Back in July, it was reported that another actor also made a negotiation with the producers to direct an episode. The unnamed actor wanted more creative and personal freedom which may alter his or her contract.

Not only in real life, Wilson also gets a development in her character’s personal department by getting a mother. The show is casting an actress to play Rachel, a very “tasteful, classy and smart” woman identified as Bailey’s mother. She will appear as an ailing patient in a holiday episode.

Kim Raver is headed to Grey’s Anatomy to break up Owen and Cristina! I kid. I think. I was just trying to get all you O&C ’shippers stirred up and, in turn, drive eyeballs to my interview with the actress. Speaking of which… In the following Q&A, Raver teases her Grey’s stint (kicking off Nov. 12), addresses reports that producers wanted her to dye, and solves a big 24 biggest mystery: Are Jack and Audrey soul mates?
When did you start work?
KIM RAVER: I’m on my second day. It’s an amazing group.
Tell me about your character, Teddy.
RAVER: She was in Iraq with Owen. She’s a cardiac surgeon. She’s really good at what she does. There’ll be some interesting stuff between Teddy, Cristina and Owen.

What exactly happened between Teddy and Owen in Iraq?
RAVER: When we first meet her, we’re not quite sure. But there’s definitely a hint of a triangle.

It just doesn’t stop for former
Grey’s Anatomy mainstay TR Knight. Several months after departing the highly rated ABC medical series and transitioning to theater, the 36-year-old has split up with boyfriend of two years Mark Cornelson, People reports.

Knight, who is best known for playing George O’Malley on Grey’s Anatomy, started dating Cornelson in early 2008. A source described the breakup as “amicable.”

After Grey’s Anatomy, the actor had landed the lead in the musical Parade, his first, that will run through November 15 in Los Angeles.

The big reveal of the episode last week on Grey’s Anatomy was that Izzie was fired (by way of a script, no less, from a bitchy HR person who bossed the chief of surgery around). We all know prior that she did ask for something like a five-week break from Grey’s for a movie and new baby Naleigh so sooner or later, her character Izzie Stevens would somehow take some time off herself.

How did Shonda and the other Grey’s people execute this little timeout? They made Izzie kill (sort of) a patient awaiting kidney transplant partly because of the pressure of Mercy West competition and partly because she was still reeling from some harsh things, namely George’s death and cancer. The question that begs asking now is this: how will they get Izzie to go back now? A corollary would be: where did she go and what did Alex do to deserve a little note telling him she left?

Justin Chambers, as Karev, did an amazing job reporting the bad news to Mer and Cristina (to hug or not to hug). And it’s true that the chief did mention that Karev was one of the people who questioned Izzie’s stamina in terms of her work. That being said, however, is there a possible way to get Izzie Stevens back to the program of Seattle Grace without sacrificing authenticity? Sure, they can snap and say “Recession over!” and hire back the people they fired, but will Grey’s Anatomy fans just as easily bite into that quickie plot fix as they did (or didn’t) her cancer-justifying-Denny-ghost-sex storyline?

One thing’s for sure. Izzie’s character has become the hotbed of insanity on Grey’s Anatomy. She was introduced as the perky, optimistic side to contrast with the dark and gloomy Meredith and Cristina. With all the harsh things that happened to her, she has grown less perky over the seasons - although she did show that naïve side, trusting one of the Mercy West newbies with the key code - and last week she reached a breaking point. Without so much as a hey, she left Karev a note saying that she’s gone, no frills and whatever’s, she’s just gone.

Or will Izzie be back at all?
