If you think viewers have had it rough wondering whether Glenn is dead or alive, how do you think his on-screen wife, Maggie, must feel? Not good, it turns out. On tonight’s episode of

, a distraught Maggie tried to get past the zombie herd outside the walls of Alexandria to go look for Glenn, but her trip into the sewer with Aaron proved all for naught.

However, Maggie did reveal to her companion another reason for her restlessness: she is pregnant with Glenn’s baby. We spoke to Lauren Cohan to get her take on her character’s pregnancy, having to shoot those scenes in the sewer, and what she makes of fan reaction to the big Glenn mystery. (Read through both pages for the entire interview, and also make sure to check out our interview with Ross Marquand.)

ENTERTAINMENT WEEKLY: Okay, first things first. Maggie dropped the big pregnancy reveal this week. When did

find out about that twist and what was your reaction?

LAUREN COHAN: I had a sneaky suspicion it was going to happen, but not from any clues. We really get no clues. I just felt that maybe there was the desire to go down that road for Maggie and Glenn. Because we talked about it in season 3 when they weren’t pregnant, but said if they were it would be okay. It’s just such an interesting topic, and I overwhelmingly feel like with the loss the life that there is a responsibility to create life. I know there are opinions on every side of the camp about being pregnant in a time like this, but I just find it really exciting. Even within the craziness now, I think it’s correct that this is the next step on that journey for those two.

So you had a sneaky suspicion she was pregnant, but when did showrunner Scott Gimple confirm that suspicion for you?

We were reading [the premiere script] and there’s a moment where Glenn says he doesn’t want Maggie going out there, and we basically as couple decide that it’s not right. And then Steven and I got the call from Scott as we were reading it, so it was kind of funny ‘cause I read it and then said to Steven, “Is this…?” And he goes “I think.” And then, yep!

Obviously, having a child in a world like this is no small decision. So how is Maggie handling the news in your eyes?

The world doesn’t stop when the world stops, and to me it feels very right that this is happening. As a storyline and as something to explore as actors and as how it will affect not just Maggie and Glenn but the entire world and Maggie’s relationship to others and Glenn’s relationship to others — it puts such a great, loaded road ahead of us. And if you are talking just about pregnancy and becoming a mother, and with every other factor as well as the uncertainty of Glenn’s fate, it makes for great story this year and great character investigation. It just feels right! That’s all I can say. It just feels right that they’re having a baby.

Look, I admire Maggie’s need to get out there to find Glenn, but her original plan of using a few fireworks to distract hundreds of walkers was garbage. You would have been zombie meat within 20 yards.

Talk a little about the compulsion she does feel to get out there and do something instead of just waiting behind the wall.

That’s part of what coming to terms with pregnancy is for her too. This season we’re going to see her limitations. It would be out of character entirely for Maggie not to do everything that she could, and not being a mother myself but thinking about that, it’s about coming to terms with all those different boundaries. Maggie burns the picture she gave him because they would never be apart again, so it’s quite a heavy thing to have on your conscience.

It isn’t whom she is to not go and try. And it’s appropriate to me that it’s her and Aaron that go. There’s definitely a kindred spirit there with those two. He’s going through a similar trajectory with the blame and the guilt. And when she realizes that he’s doing it for his own reasons, she allows him to come with her. She’s not to be stopped, until she’s stopped.

Ross told me that even though Aaron and Maggie have not been on screen a lot together that you guys had decided to play it as if they had become friends and we just haven’t seen that play out on the show.

Yeah, that’s what I love about this show. You just have slices, but there’s a whole world going on around it. There’s Maggie and Deanna’s relationship, the conversations that Maggie and Glenn have, and it’s really for the audience to glean what they want. It’s funny because, like, Alex Breckenridge and I are really good friends now, and she and I have never had a scene together, but you have to believe that there’s the community of people that interact constantly, even more so in the normal world. There are neighbors in my building I haven’t met in five years.
