'Under The Dome': Rachelle Lefevre thinks Julia will solve the mystery

If there's one character on "Under The Dome" who has a chance of figuring out exactly what the alien-seeming dome is, it's Rachelle Lefevre's Julia Shumway. The newspaper editor is inquisitive, to say the least, and she seems to be steadily digging her way through every plotline in the whole show -- including eventually discovering the fate of her husband, which audiences have known since the show's very first scene. She got close to discovering that in episode 4, but just because Barbie has her fooled doesn't mean she's going to stay that way.

"Julia is determined and there's no discouraging her," Lefevre tells Zap2it at San Diego Comic-Con over the weekend. "She's persistent. She'll get her answers."

Julia's persistence may be an asset to her at the moment, but it hasn't always been. Lefevre said her character's backstory -- her determination got her fired from a big-time job in Chicago -- was important to how she played her. 

"I knew Julia's backstory about why she got fired from her job in Chicago before the series started," she says. "That was something they told me was going to come out. And it, you know, it's a two minute scene in one of our episodes, and maybe seems like a small moment. And whether the size of the revelation is large to the audience or not, for me it was definitely a huge deal. Because what it says to me is that you have to learn that the ends don't justify the means. And I think that's a really good theme of our show."

That will likely prove true as the season continues to play out. Plenty of characters are making bad decisions that they hope will be justified in the end, and they can't all be in the right. All that's known at this point is that somebody is going to get some answers about the dome at some point, and Julia will likely play a part in it.

"I definitely think she'll be a participant -- an active participant -- in getting answers about the dome," Lefevre says. "She's always following different characters around and sort of keeping tabs on what everybody's up to, and I don't think that she can do that continuously without catching on if anyone makes any headway."

"Under The Dome" having just begun airing, this was Lefevre's first time at Comic-Con with it. But it was her second Comic-Con overall, her first being for the role of Victoria in the first two "Twilight" films. She said that it hasn't been difficult to leave that legacy behind, though.

"Honestly, when you have something great like "Under The Dome" -- I'm here for such a great reason that it just feels like that's my whole world right now," she says. "I'm enjoying the ride.

"Under The Dome" airs Mondays on CBS at 10 p.m. ET.
