Carrie Preston is back on "Person of Interest" as Grace Hendricks, the former fiancée of Harold Finch (Michael Emerson, who is married to Preston in real life). Finch faked his death to keep her out of harm's way, but it appears that Decima's uncovered their connection and is out to kill her.

Preston is in high demand. This past season, she was not only a regular on HBO's "True Blood," but she guest starred on "Person of Interest" and "The Following" and won an Emmy for her work on "The Good Wife." Yahoo TV spoke with Preston about finally bonding with the rest of the "POI" cast and whether she thinks Grace could handle the pressure of working for The Machine.

Watch an exclusive clip featuring Preston's return to "Person of Interest":







We've always known that someday Grace would find out Harold was alive, just by the rules of drama. Is that a moment that you've thought about as you come back each time?

I sort of hoped for that, but at the same time, there's something so wonderful about — and it's age-old in storytelling — the star-crossed lovers. If there was some happy resolution, the story would be over! I think the writers are very smart in the way that they're unfolding the relationship between Grace and Harold, both in flashbacks and present day. I think that it's propelling the storyline forward, and it's also giving a very moving and sometimes unexpected glimpse inside of Harold's heart, which we don't get to see that much.









As an actor, would you like Harold and Grace to have a happy ending, or do you secretly kind of hope to get the grand Romeo and Juliet tragic farewell?

I always root for a happy ending; I think we all do. We all secretly want it. But life is more complicated. I'm really happy to play any of it. I just want to keep playing the role; I'd to work it somehow as a long arc. So, if it means keeping them apart for four seasons, then I'm all for that. If they do bring them together, I hope she joins the team!

Does she have the fortitude to handle that?

I don't know! It'd be very interesting. I'm getting to know Grace along with the audience, because I come in periodically and touch down into her again and find out new little things about her. It's a fun detective game, in a way, when you're someone who's not playing a character full-time.



She's very bright, and she inspires him even from afar. Who knows? The thing that is so great about "Person of Interest" is it keeps surprising you. Just when you've figured out the formula, they switch it up. That's what keeps the viewers watching.

We've only ever seen Grace in calm and conversational scenes. This week, we finally get to see her running around getting shot at. Did you have fun with that?

I did. And it was also fun because I got to work with the other cast more. I got to get a real glimpse into what they're up to the whole time for 23 episodes a year — we only do 10 on "True Blood." They're out on location in very cold weather. I got a real glimpse into what my husband's been dealing with.



It was just fun to get to know his co-workers. It's such a wonderful experience playing a pretend person who's in love with my husband, who's playing a pretend person. I don't think either one of us could have ever dreamt up something like this, so we really enjoy it.
