person of interest season 3 episode 21 carrie preston cbs 'Person of Interest' Season 3: Carrie Preston teases Grace's return

The next conflict on “Person of Interest” hits very close to home when Greer uses Harold Finch’s former fiancee Grace Hendricks to draw him out of hiding. That means two very important things: Carrie Preston is returning in Season 3, episode 21 “Beta,” and she will no longer be playing a flashback version of her character.
During a recent phone interview, Zap2it spoke with Preston about her return to “Person of Interest” and the effect starring on the show has had on her real-life husband, Michael Emerson. Spoiler alert: It’s pretty adorable.
Zap2it: How was this episode a different experience from the earlier times you’ve been on “Person of Interest”?
Carrie Preston: One of the main differences is this episode is not flashback. We’re not going back to a time where we’re having to set the relationship and give the audience some exposition about how Grace and Harold got together. That brings us into the current chaos of where the show is right now with what’s going on with Harold and his world and his Machine and the competition with Samaritan and all that stuff. Harold’s efforts to protect Grace from danger are not fully successful.
She currently thinks he is dead, so can we expect there to be any complications with the fact he is actually alive and needs to save her?
His number one priority is to protect her, and so that is not going to change. He is definitely going to do everything that he can to make sure she’s OK. And whether or not he’s successful at that is what you have to tune in to see.

Do you think there’s any hope for him and Grace to have some sort of happy ending?
One would hope, and I know that’s the hope that he’s holding onto. He’s such an interesting, mysterious character, it’s always so wonderful to see any personal side to him. Anything that’s revealed about his past or feelings, everything is a little nugget not only to the audience but to the characters around Harold Finch who find him to be super mysterious. 
I don’t know what the writers have in store, but they do want to tease things out. If everything was a happy ending, then they would have nowhere to go. I think there’s something that we all relate to with that kind of star-crossed lovers conflict. It’s age-old in storytelling, and I think it just makes the audience root for him and root for the two of them.

And root for you coming back more.
Yes, exactly. [laughs] I wish for that too.
There are so many not-so-fictional storylines on this show, is there ever any technology paranoia that Michael brings home with him after three seasons?
He’ll say things like, “Well, you know, Harold Finch would say that I need to change my password right now.” [laughs] He has been changing his passwords on a lot of his things just to shake it up. He changed his email address to something that wasn’t specific to his own name. I think part of it has rubbed off on him a little bit. Now, you have to remember that Michael is — or maybe you don’t know — but Michael, I wouldn’t say he’s technically savvy. [laughs] Sometimes he’s a bit of luddite. 
I kind of dragged him into the digital age out of necessity. If it was up to him, he would still be sitting in a library somewhere reading a book. It’s very cute to introduce him to the world of technology. I’m always the one he turns to for computer advice and for iPhone advice. Everything that has anything to do with technology, I’m always the one that’s in charge of that in the household. It’s ironic.
“Person of Interest” airs Tuesdays at 10 p.m. ET/PT on CBS.
