Turn

 is the twelfth episode of the second season of Under the Dome.

Synopsis
The Dome continues to slowly contract, causing periodic tremors and other damage. Junior and Lyle review Pauline's notebook, looking for any clues that might be helpful. Lyle points out one picture and interprets it as he and Pauline going to Heaven together. Melanie's condition continues to worsen and Rebecca gives her a blood transfusion. Barbie takes Hunter to the edge of the Dome and tells the men in black that he demands to see his father. When he arrives, Barbie convinces him that Melanie is alive within the Dome and the only way to save her is for him to return the Egg to Chester's Mill. He is told that the way in is the Red Door. As Don leaves to get the Egg, the Dome's contraction stops. Big Jim encourages Pauline to paint something, even though her visions have stopped. When Don reaches the Egg, he picks it up and surprisingly it does not hurt him. As he turns to take it to the Red Door, the men in black stop him, saying they have their orders. This causes the Dome to start contracting again, and Melanie is in distress. One of Pauline's paintings shows eight hands supporting Melanie, and the other (unseen) is dripping blood. Melanie is taken to the center of the Dome where the Egg was discovered. Pauline talks to Junior and seems to be saying goodbye to him. Since Angie was killed there are only seven Hands available, but they realize that Melanie really counts as two Hands ... one representing the past and one for the present. When they hold both of her hands, the ground opens up and Melanie is sucked into a hole. Big Jim congratulates Pauline with a kiss and as they are kissing, Lyle stabs her in the back. As Pauline lies dying, Lyle tells Big Jim that now he can join her in Heaven, and encourages Big Jim to stab him and finish the job. Big Jim does so in a fit of rage.
