[Warning: This story contains major spoilers from Under the Dome's Season 2 premiere. Read at your own risk!]

Over the course of Under the Dome's first season, many Chester's Mill residents have fallen victim to the power of the dome, but the death in the closing moments of the Season 2 premiere was especially shocking.

The second season picked up with Junior (Alexander Koch) moments away from pulling the lever that would send Barbie (Mike Vogel) swinging with a noose around his neck. But the sudden magnetization of the dome caused residents to pass out and sent an SUV careening into Linda (Natalie Martinez). RIP! But the closing moments of the episode — after Julia (Rachelle Lefevre) deduced that the dome magnetized because it was (ironically) trying to prevent more death — proved that there is a new threat the residents should now be worried about.

Mega Buzz: Will the new characters cause romantic drama between Julia and Barbie?

After Angie (Britt Robertson) chased after Melanie (newcomer Grace Victoria Cox), whom Julia had pulled out of the lake earlier, she found something shocking inside a locker, but was then immediately cut down by a mysterious figure wielding an axe. That's right! One of the Four Hands has been killed. How will this affect the dome? What was inside the locker? And will Angie return? TVGuide.com caught up with Robertson to get the scoop:

Is Angie really dead?
Britt Robertson:
Angie is actually dead. She's for sure dead after the first episode, but it's a Stephen King show, so whatever that means to the audience. It's very vague what dying is and where the season goes, so who knows? I might go back to Under the Dome one of these days. She's dead, but dead for now.

How did you find out that Angie was going to die?
Robertson:
I actually found out from the other person who dies, Natalie. She called me when I was in Vancouver shooting Tomorrowland [also starring George Clooney]. I got a message from her. I think it was, "Hey, we're dying. Let's get a drink!" I had no idea what she was talking about, really, because no one told me, and I had no idea what was happening with the story lines at all. It was shocking, for sure. I didn't think that I would go that early on in the season. But ... it was a cool, exciting way to die. As soon as I read the script and saw that I wasn't dying in the first five minutes, I was a little more comfortable with the idea. And knowing that it would be a cool exit, and knowing the Stephen King is writing the episode, it doesn't really get any better than that. It's hard to be upset about the whole thing.

In the book, she died so soon, so at least you outlived your counterpart.
Robertson:
Yeah! The thing about dying with this show is a lot of times that's where the exciting story line is, so you almost welcome the idea.

Mega Buzz: Is Barbie also headed for Zenith?

Is there a part of you that's still disappointed that Angie didn't survive her time under the dome?
Robertson:
I thought she would be the strong-willed woman who would get them all through being under the dome. I thought she would be a part in taking the dome down. But I think she was maybe a little too strong-willed and hotheaded. That got her into trouble.

Whereas Linda's death was inadvertently caused by the dome because of the magnetism, Angie's death is a straight-up murder, so how do you think that will affect the town?
Robertson:
There's never been a shortage of killings under the dome, even if it was by the hands of the humans. I don't think it's a new concept. A lot of the town will look to the obvious choices: Maybe it's Big Jim (Dean Norris) because they've always had a [tumultuous] relationship and they're always going at it, or maybe Junior can't take it anymore because Angie just doesn't love him. A lot of people will look to the obvious choices, but I hope that they're surprised. I still don't even really know who killed me. Hopefully they'll find some peace with Angie's death. That's all I hope for, is that it only gets the audience even more excited to take out whoever killed me.

Many dead characters have already returned under the dome, so is there a possibility that we'll see Angie again?
Robertson:
Most definitely. I always like to think there's a possibility for anything with this show. I'm very open to coming back. There is always really cool story lines that they create with dead people. I'm hoping to get something in that world, where they bring me back, but I'm not quite Angie, you know?

I have a feeling that Junior didn't kill Angie. Will he go to great lengths to find out who killed her?
Robertson:
I hope he does! Good Lord, he kept me locked up in a fallout shelter for long enough. He better care enough to find out who my killer is and take them out.

Mega Buzz: What's the deal with the mysterious Melanie?

Do you know what shocking thing Angie was looking at in the locker when she was killed?
Robertson:
No, not at all. That's what is so funny when we shoot those scenes. You beg for information and for something to go off of, but at the end of the day, it ends up just being the actors coming up with crazy ideas, with half of them not even making sense. I have no idea, but it's going to keep me staying tuned in to the show.

What have you been working on since you left Dome?
Robertson:
Yeah, so bye, bye, Dome. Then I worked on a film in Los Angeles called Cake with Jennifer Aniston and a really awesome cast. It was a really fun experience. It was a different character than I've done before. It's a small indie movie and it's a really cool script. Right now, I'm working on a film called The Longest Ride, which is based off a Nicholas Sparks book, with Alan Alda, who is amazing, and Scott Eastwood. There's a really great cast for the flashbacks of Alan Alda when he's younger, and the two characters who play young Alan Alda and his wife are Oona Chaplan and Jack Huston and they're incredible. Just to even be working in this town is a battle, so the fact that I'm working with people that I admire and I can learn from, that's just another bonus.

Is there anything you wish you got to do on Under the Dome that you didn't get a chance to do?
Robertson:
Yeah, I always wanted Angie to be the cop for a day. Like all the cops went under, Junior is not a deputy anymore, there is no one running the sheriff station, and somehow Angie gets in charge of the guns, the rules, the town, everything. I wanted to wreak havoc. Unfortunately, they didn't let me do that. I don't know why. [Laughs]

Under the Dome airs Mondays at 10/9c on CBS.
