Barbie and Julia prepare the residents of Chester's Mill for a potential evacuation and discuss the situation in Zenith, Julia believes she should go first and negotiate for the townspeoples' safe passage, but Barbie is against the idea, believing it to be unsafe for her. When Big Jim interrupts their meeting, he demands to be involved and offers to go first over the cliff along with the egg. They however, are unaware that Big Jim had met with the men in black at the Dome's edge and has a deal of his own set up. Later, Barbie discusses his vision while returning to Chester's Mill, that of him as a boy and a red door which Melanie helped him paint. He believes Melanie to be his sister, the daughter of a woman his father had been having an affair with, and she tells him she remembers. Junior meanwhile brutally attacks Sam for killing Angie and is faced with an apparition of Angie, who convinces Junior to spare Sam's life. Melanie decides to hide the egg through concern in Big Jim's bunker with the help of Junior. When the egg emits a high pitched scream, Pauline is faced with crippling headaches and paints her visions. Concerned for his wife, Big Jim locks her inside the house, and finds the egg, along with Joe and Norrie in his bunker. When he tells them of the effect the egg is having on Pauline, he forces them at gunpoint to the school and throws it over the cliff edge. Immediately Chester's Mill is faced with earthquakes and Melanie collapses. Barbie notices Phil making his way towards the cliff edge, and as the portal to Zenith is now gone, he finds Phil impaled on the rocks below. Big Jim returns home and learns Pauline's headaches have stopped, but she is disappointed when he tells her what he had done with the egg because her visions are now gone.
