Nathan has a wife and daughter in the alternate Haven.
William tells Audrey that he needs the old Haven in order for her to remember who she really is, and if she helps him it will be less painful for everybody, but he's willing to use the painful route to get what he wants. He also tells her she likes and needs the Troubles.
Duke did some recon on Audrey Parker and found her in the FBI, but it wasn't her, so he wonders why she's so certain things are going to go wrong.
