Talk about some amazing news! And I'm shocked that they kept it a secret too! But, still, I'm thrilled that Dr. Erica Hahn has officially joined the Seattle Grace staff and is now a series regular. For all the info, check out Michael Ausiello's interview with Brooke Smith!

Congratulations!
Brooke Smith: Thanks!

You must've had an idea this was coming….
Smith: Honestly, I wasn't expecting it, [probably] because I didn't want to be disappointed if it didn't happen. I thought it was really cool when you [floated the idea], because I thought, "Wow, I didn't even think of that!" And literally a couple days after we spoke, they called.

Did they come right out and offer a full-time gig? Or were they just offering another guest spot?
Smith: No, it was, "Hey, can you come full-time?" Thank god. I couldn't handle any more dabbling. It's too much. [Mock anguish] I feel like I want someone to commit to me already!

What was your first reaction?
Smith: You know, we were kind of excited. [Laughs] I say "we" because my husband and I were like, "Wow, OK." We had just finished [renovating our apartment] in New York, and put down a deposit on school for our little girl. But, aside from that, we just said, "All right, I guess we're moving to L.A. for a little while." But we're going back to New York at the end of this.

Do you like that Dr. Hahn is a little bit of an antagonist?
Smith: Yeah. I've heard people say [Dr. Hahn] is abrasive. [Laughs] Dr. Hahn is a workaholic and she's very professional and, you know, I think she feels that there should be professionalism at work, and when other people do things that aren't professional she gets a little upset.

And lord knows, there are a lot of people acting unprofessional at Seattle Grace.
Smith: There are! For god's sakes, c'mon, it's a hospital, people!

It's not a Motel 6.
Smith: Exactly! Lord.

Since you're sticking around, I guess it's safe to assume that they're going to delve a little more into Dr. Hahn's background… maybe give her a love interest?
Smith: I think so. Honestly, as of now, there's only a little hinting. I'm getting some suggestions….

Like what?
Smith: There might be a certain man there who's interested in me. But I don't know what Dr. Hahn will think of that. It's really interesting. I haven't worked like this before. We start shooting the next episode on Monday and I don't have a script yet. We'll get it tomorrow, and you just sort of read them out loud with everyone, and you're like, "Oh my god!" I know a little bit about her. And, certainly, I have a dialogue with the writers and I ask them questions and they sort of steer me down their same path. But I don't think anyone knows what's going to happen…. The other day I joked, "I know who I'm hooking up with!" There's this surgical nurse who's always there. When she's there I'm thrilled, because she always makes me feel very real — 'cause she's a real [surgical nurse]. I turned to her at one point and said, "Are you single on the show?" She doesn't even have a name on the show and I'm already trying to hook up with her.

I can see Dr. Hahn hitting it off with Cristina.
Smith: Secretly, we pushed for that. You know, Sandra [Oh] and I played lovers in [the off-Broadway play] Stop Kiss.

You know, there were rumors a while back that Cristina might be bisexual….
Smith: I know. I heard those rumors.

Then it's destined to happen!
Smith: That's what I think. But I don't know….

I think Dr. Hahn would make an awesome lesbian.
Smith: I think so, too.

Could it happen?
Smith: I honestly don't know. I've certainly let [the producers] know I'm open to it.

What was their reaction?
Smith: They were like, "OK, duly noted!" I think they wanted me to shut up already.

The fact is, Seattle Grace needs a gay character.
Smith: Well, hey, you called it that I [would be] on the show full-time, so….

Did the cast welcome you back with open arms?
Smith: They've been great. Everybody's great. It's very comfortable… which is weird. It feels like it shouldn't be, because it's such a big show.

And it hasn't always been the happiest place to work.
Smith: I guess that was last season. I haven't seen any of that. And I didn't see it the last time I was there. Maybe it's just me. Maybe I'm in some sort of bubble.

Any Grey's scoop you can give me before you go?
Smith: I heard Seth Green is coming.

Eh, that's old news. Are you going to be in scenes with him?
Smith: Not yet. But we're doing a two-parter now, so maybe in the second part. I'm not involved with him in the first part.

Who are you involved with in the first part?
Smith: I've been working with Dr. Sloane… Izzie… and Alex. And I finally got to work with Dr. Torres.

Well, this is exciting news — mostly because I predicted it.
Smith: I know. God knows what'll happen when I hang up [this time].

Shonda Rhimes is going to call and tell you that Dr. Hahn is gay.
Smith: Oh my god. Should I call you back if that happens?

You better!
Smith: All right, I will. I totally will.
