I don't watch the show, but I know plenty of people that do. Any 'Grey's Anatomy' fans out there? Last night's episode was a jaw dropper (or so I've heard) and this morning everyone is talking about what will happen with their favorite characters. EW sat down with Grey's creator,  Shonda Rhimes to try to make sense of it all. 

Let's get started!

Rumors have been swirling all year that Katherine and TR wanted off the show. The season ends with both their characters' lives hanging in the balance. Purely coincidental?

I don't think there are any coincidences. I think Katherine's stated publicly that she's happy to stay. I think that there have been lots of rumors about TR, but TR's never said anything. Take from it what you will.

This kind of cliffhanger almost seems tailor-made to capitalize on some of those headlines and generate buzz.

You have to remember, I have two shows. It's not as if I spend a lot of time reading the press. We talk about stuff in the writers' room that other people have read, but, mostly, we were really moving on character. Every year at the beginning of the season I pitch what the end of the season is going to be. And I literally sat down and pitched the last 10 minutes of this season at the beginning of the season, so we were headed towards the place that we knew we were going to go.

Do you know which one of them lives and which one of them dies?

Yes. And I don't know that you should be saying "which one of them lives and which one of them dies." I know what happens to the characters.

Katherine said in a recent interview that she was as much in the dark about Izzie's fate as anyone. Do you keep this stuff close to the vest in order to prevent leaks?

There was a joke for a while there that if I got hit by a bus [no one would] know how to end the season. I do feel like a secret's not a secret if anybody knows about it. It was really about trying to keep the storyline as secret as possible, because I wanted the last moment of the season to be a real surprise.

There was criticism that the Denny hallucinations went on too long without an explanation. Looking back, do you regret not revealing Izzie's diagnosis sooner?

Do I regret it? No. As writers, we had a lot of fun figuring out how we were going to tell that story. I don't regret anything we've done. Every season is a learning process for me. This is my first television show. Granted, I've done five seasons now, but it's still my first television show. As we head into season 6 everything is still a learning experience for me. It's been a great, crazy experiment that has happened fairly publicly, but, for me, it's been my learning process.

There was a period there where the show was being relentless mocked, especially where the "ghost sex" was concerned. Did you ever take it personally?

You're the first person to tell me that, because I, of course, don't read a lot of press. One thing we've gotten used to is being in the public eye and we learned to let everything roll off our backs. We knew where we were going; we had a road map. The rest of the audience didn't know where we were going. We all thought it was really surprising that anybody thought there was a ghost on our show. We're a medical show. We thought it was surprising that anybody would look at it and go, "Gee, that's a ghost." So that was surprising to us. But, other than that, we took it with a grain of salt.

Did Meredith and Derek really get married last night?

Their wedding was a Post-it note. We had a big series of discussions about it in the writers' room. I felt very strongly -- very very strongly -- that the last thing Meredith Grey would do is put on a wedding dress and walk down an aisle. It just felt wrong to me, Meredith being Meredith. And the Post-it wedding will have big reverberations next season.

Will we still get an official wedding at some point?

I think they feel it is an official wedding.

Meredith and Derek fans felt a little cheated by the 100th episode because they were led to believe one thing and they got another.

Yeah, I saw a lot of people felt like, "Oh my god, they promised it was going to be a Meredith and Derek wedding." I never said it was Meredith and Derek's wedding, I said it was their wedding day.

Have you figured out how you're going to work around Ellen Pompeo's maternity leave next season?

We're actually still talking about that. The writers have disbanded for the season and we're going to come back together at the beginning of June, so we're still talking about what we're going to do and what that's going to mean. Her maternity leave doesn't actually come into play until later this season. We will have shot a number of episodes by that point. [And] Ellen is extraordinarily optimistic about what she's going to be able to do. She's such a trouper and I'm really am grateful to her for it. We'll take it as it comes.
