In case you hadn’t realized, Chester’s Mill is not the safest place to live, especially with the introduction of Marg Helgenberger’s mysterious new character Christine Price in the third season of Under the Dome.

Introduced in the season premiere as a therapist sent by FEMA to help the residents of Chester’s Mill recover, Christine clearly isn’t who she says she is since, you know, everyone was basically living in an alternate reality. “I have an agenda for Chester’s Mill and have a plan that I put into motion that I’m trying to get the whole community behind,” Helgenberger teased during Thursdays’s Comic-Con panel. “Things are getting pretty desperate with [dwindling supplies]. I refer to this as a kinship, a collective. Some people go along and some people don’t.”

Those who don’t go along with her plans may be the most in danger. “Sometimes a series can have deaths that don’t really mean anything,” executive producer Tim Schlattmann said. “I think this season, these deaths are really going to matter. It’s all going to start to build in tonight’s episode and moving forward. Things are going to get bananas.”

In speaking of an episode the show is currently filming, Helgenberger teased, “I couldn’t believe what I do at the end of this episode. I almost started crying reading that.”

In Christine, “Big Jim [Dean Norris] has really met his match,” Shlattmann said. “The thing that makes him such a foe for Christine is he’s a narcissist.” But their rivalry will give Julia (Rachelle Lefevre) a new appreciation for Big Jim and could be the key to saving Chester’s Mill. In truth, the reach Christine has may be much bigger. The fate of “humanity may very well rest on [Colin Ford’s Joe].”

But with death comes new life. “For Barbie [Mike Vogel], he might want to start thinking about shopping at Toys R Us,” Schlattmann teases.

Under the Dome airs Thursdays at 10 p.m. ET on CBS.
