Julia leads Barbie into the forest to show him the pink egg with the mini-dome. He suggests that the egg is projecting the dome like a planetarium. When they get to the spot in the forest, they find a spherical half-hole in the ground but no sign of the egg or the mini-dome. Julia insists that it was there and they wonder where it went, just as Linda calls Barbie to tell him that there have been shots fired and she needs him. Barbie takes off while Julia stays behind to find it.
Joe shows Norrie how to catch chickens so they can cook one for supper. They talk about the words "the monarch will be crowned" and wonder what it means, and Joe suggests it may relate to the butterflies that gathered on the dome. Joe says that they'll go back to the mini-dome after they catch dinner.
At the diner, Big Jim comes in and tells Angie that things are looking up now that the water is flowing. He has worked out a food deal with the farmers and Angie says that she plans to keep the diner going because she feels that it's important. She asks Big Jim for the deed, free and clear, so that she can be responsible for something for the first time. Big Jim says that he'll think about it.
When Barbie arrives, Linda explains that Mr. Feldman's neighbor, Ted Utley, fired off a few shots when a freak pounded on his door claiming that the dome was talking to him. One of them grazed Feldman. Barbie and Linda find the man, Larry, ranting and raving. Linda confirms that Larry uses drugs and he explains that he uses Rapture, which be bought from Coggins.
At the diner, Junior comes in and Angie orders him out. He insists that he won't hurt her but she says that it's her place and she's refusing him service.

Big Jim goes home and discovers that someone has left the front door open. He draws his gun and cautiously goes in, and finds a woman waiting for him: Maxine.
When Angie wakes up, she finds herself in the back of Junior's squad car. She tries to get out, screaming, and Junior tells her that she's safe. He explains what happened and drives up to her house. Angie is surprised that he's letting her go, and Junior says that he'll see her around.
Julia tells Joe and Norrie about the disappearance of the dome. Norrie says that Carolyn is still grieving and wants some time alone.

As Angie takes off her sweater, they notice her butterfly tattoo on her shoulder. She goes to get a drink and Norrie and Julia suggest that Angie might be the monarch who will be crowned. Joe points out that the butterfly is blue and yellow, and monarchs are orange. Norrie suggests that they use the yagi that Dodee built to track the dome energy, and Julia says that she'll talk to Dodee alone because the engineer doesn't trust the two teenagers.
Big Jim asks why Maxine is inside the dome and she explains that she left Westlake to see him on the day that the dome came down. She says that she wanted to talk about their arrangement and how Big Jim was losing control of Duke and Coggins. Big Jim points out that the Rapture is hers, and assures her that Duke and Coggins are no longer a problem. He wonders where she's been since the dome came down, and Maxine claims that she borrowed a home belonging to a couple outside the dome. Maxine is well aware of what Big Jim has been doing, and figures that the two of them need to work together.

The engineer doesn't trust the teenagers, but assures Julia but she didn't tell anyone about them.
At the police station, Big Jim is waiting when Linda and Barbie come back. They explain what happened and Big Jim suggests that they collect everyone's guns to avoid any future trouble. When Linda points out that they have a Constitutional right to bear arms, Big Jim points out that they're a country unto themselves. Barbie is forced to admit that it didn't go well in Iraq, and Big Jim offers to go on the radio to promote the idea as voluntary. Linda reluctantly agrees and Barbie offers to help collect the guns. Big Jim wonders if he can count on him and Barbie points out that he agrees with him. As Big Jim walks out, Barbie tells Linda that he isn't so sure but he's going to stay close to find out what's going on.

Junior starts to show her and Angie hesitates before going after her.
At the diner, many of the townspeople show up to turn in their guns. Utley isn't there and Dres Johnson tells Big Jim that Utley said that they'd have to kill him to get his guns. Big Jim tells Barbie that Utley has always been tightly wound, and his family was killed in a car accident when the dome came down. The councilman prepares to go confront Utley, strapping on a gun, and tells Barbie that they're dealing with an insane man. Barbie picks up a rifle and offers to go with him, and Big Jim accepts.
Joe, Norrie, and Julia go into the forest and follow Truman. He gets the scent and leads them to a... a pheasant hiding in a bush.
Linda goes to the propane warehouse and discovers that the door is locked. Andrea comes over and says that she's seen a lot of suspicious things from her house across the street. She tells Linda about all the trucks that have been in and out, and admits that she told Duke. However, he dismissed her concerns and sounded very nervous when he did. Andrea tells Linda to talk to Julia and confirm that she reported the same thing to her. Once Andrea leaves, Linda notices a security camera mounted on the wall. She ignores it and shoots off the lock, and finds dozens of propane tanks inside.

Junior shows Angie the painting, which shows him on a hill looking up at pink stars.
Big Jim goes into Utley's house and tells him to put the gun down, while Barbie circles around the back. Utley is sitting on the bed, surrounded by his guns, and Big Jim puts his gun away and comes in. The man says that he can't turn in his guns because the dome has already taken everything else from him. Utley opens his hand, revealing that he's holding a hand grenade, and Big Jim grabs it while Barbie draws a bead on the man. Big Jims says that he knows how he feels because he lost his wife, and promises that it will get better. Utley doesn't believe it and shoves him away, but Big Jim grabs him, yanks the hand grenade away, and inserts the pin. Barbie comes in and Big Jim has him take Utley to the clinic. As Barbie leaves, Big Jim thanks him for keeping his cool and not shooting him by accident.
Linda breaks into the warehouse office and checks the security monitors. She plays back the recordings and sees Maxine paying off duke.
Junior suggests that Pauline knew that the dome was coming and figures that it's related to what Angie said. He insists that he isn't crazy and neither is Pauline, and now he and Angie must both be part of it. Junior is happy that they're connected by something greater.
At the diner, Barbie and Big Jim put away the guns and Maxine comes in and congratulates them. Big Jim awkwardly suggests that she doesn't need to be there, and then introduces her to Barbie. Maxine goes over and kisses Barbie, and explains that they know each other.

Barbie remains silent at first, but finally greets Maxine. Big Jim wants to know how they know each other, and Barbie points out that Big Jim has been lying all along about the propane. Maxine says that the disarmament was part of her plan, and Barbie figures that they'll start up gambling and alcohol to keep the people amused. When he objects, Maxine says that he doesn't have a choice and is more than willing to reveal both of their secrets to the townspeople. She tells them that they're both working for her now, and assures them that she has insurance in place in case something happens to her.
Big Jim starts loading the guns up to take to the cement factory and Maxine reminds Barbie about how they met several months ago at a bar.

She knows that Barbie and Julia are involved and warns him that she knows everything that everyone has been doing in the last eight days.
