The central mystery of Season 2 of The Affair was finding out who murdered Scotty Lockhart (Colin Donnell). But along the way, viewers found themselves pondering an even more interesting question: Who is baby Joanie's biological father? Is it Noah (Dominic West)? Cole (Joshua Jackson)? Someone else entirely?

The good news is, as show creator Sarah Treem promised, the identity of Alison's (Ruth Wilson) baby daddy will be revealed in Sunday's episode. The bad news, at least for Alison? It's going to complicate things... a lot.

The episode is told from Helen (Maura Tierney) and Alison's perspectives, chronicling their lives after Noah went to prison. Alison's timeline picks up a year before Noah's release, and we see that she hasn't been coping that well with his imprisonment, to put it mildly.
