When three Haven residents fall down dead after hearing a baby cry in the distance, Audrey and Nathan know that William is up to his old tricks again. It's no surprise when William shows up to claim responsibility but what he's done is even more devious than they could have imagined.
The Harker family has had a long-standing curse for years. Whenever anyone in the Harker family cries, someone else in Haven will hear the sound and die on the spot. For generations, the Harker family has taken great pains to avoid crying but William has activated the curse within the newest addition to their family: a baby.
For the first time ever, Audrey is stymied. How can she keep a baby from crying? Usually, she talks to people to help them understand their Trouble and how to push past it but, this time, she can't.
William has a solution for Audrey but she doesn't like it. It turns out that
William created this un-fixable Trouble specifically to force Audrey into creating a Trouble herself—a polar opposite Trouble to counteract the baby's.
William is hoping that the process of creating a Trouble will remind Audrey who she really is and then she'll (finally) return to him. If everything happens according to his plan, William will get Audrey back and the two of them will rip Haven to shreds.
After exhausting all other options, Audrey finally gives in and tries to create a Trouble by creating a "silence" Trouble, which Medical Examiner Gloria's boyfriend takes on. The idea is that since Gloria's gentleman friend is partially deaf in one ear, by giving him a silent Trouble it can create a sound barrier that will lock in the sound of the baby's cries and spare others from hearing it and dying. She succeeds in creating the Trouble, giving credence to
William's claim that she created all the Troubles in the first place. Sadly, her new Trouble does not balance the baby's. She plans to try again but Duke can see that she's starting to enjoy the power of creating Troubles. His suggestion is complicated but he thinks it's safer, overall. Duke convinces Audrey to reactivate his family's Trouble so that he can kill Ben Harker, the baby's father and end their Trouble for good. It's a grisly idea but can it work?
