Audrey and Nathan are talking about what happens next, what they need from the void to build the barn. Saving the world, waiting for Duke to get back with Haley. He comes back.
Audrey is worried about Nathan going into he void because Charlotte's note said humans don't last long in the void, and she's not...
Dave is in jail for the murders.
Nathan can't believe nobody remembers Haven outside the fog. Nathan explains to Duke why he needs to go into the void. Duke thinks he's nuts, telling him about his vision. In the future, Haven was hell on earth all because Nathan went into the void and never came back. Croatoan won. He came back to stop Nathan from going into the void. Nathan says he needs to make sure he comes back, because he has to go.
Vince is updating troubles. He wants to try to find a Trouble that will allow them to cut Dave's tie with Croatoan. Dwight settles in to help.
Hayley turns out to be pretty good with her Trouble and creates a thinnie. Nathan goes through. Hayley will create another for him to return in two hours.
It's green in the void. For some reason, Nathan could see the thinnie, even though it was gone on the other side. Hmmm. It's barren there. How the hell will he find a controller? Does he even know what a controller is?
Duke is at the piano when Audrey returns. He says Hayley is impulsive and doesn't know how to control her Trouble. Audrey is angry with Duke because when she needed him, he walked away. He is angry for always being needed. If he had known why a member of the Colton family was needed, he wouldn't have come back.
A girl comes to see Duke. Everything she touches blows up. She's a little annoyed and even more so when she realizes Duke is immune to her. She decides to blow up the house.
Vince finds a reincarnation Trouble, the one that split Audrey and Mara into two people. He thinks if he splits Dave and Croatoan, he can just kill Croatoan.
Meanwhile, in the void, Nathan falls down into a pit and William finds him. Nathan tells him that Mara sent him to get the controller so they can battle Croatoan.
Just after Nathan finds the controller, someone who looks like Audrey appears by way of a very bright light with stark white hair and in a white gown. WTF?
Vince and Dwight take Dave to the Troubled guy. It's probably not the best idea after William noted Croatoan was in a safe place being inside of Dave. Oh.Dave just killed the guy. That was easy.
For some reason, Duke doesn't bother telling Troubled Lisa that he's back in town to save everyone or that there is an actual plan in motion to make things better.
When William answers White Girl's question incorrectly, she starts a countdown to destroy the controller. Nathan jumps in and tells White Girl that the barn was created to save Mara, so that she would recognize she is not evil and could be better, more like Audrey, in fact. He is the right person. She disappears.
William wonders why Nathan is talking about Mara in the past tense. A fight is underway and Hayley turns into a bad girl. She refuses to keep the doorway open. She doesn't want to lose the ability to do what she can do. Duh.
Hayley ditches the ring and walks through a fence and leaves. The thinnie closes and the void starts to crumble down upon Nathan and William.
William's arm is stuck and they're both stuck in the cave.
