In the new season, Ambrose searches for Jimmy and Nick's relationship that had been before the accident, and perhaps Jimmy begins to collapse again. Ambrose is on a new path as she investigates Jimmy's past. Over time, she gives birth at night, but Jimmy's anxiety reaches the breaking point again.
It's a tension that only builds throughout each episode, as Jamie is someone who is willing to do terrible things but will still ultimately process it as being someone else's fault.
