Alison Lockhart (Ruth Wilson) gets another surprise visit on Season 2, episode 10 of Showtime's "The Affair." In episode 2, her estranged husband Cole Lockhart (Joshua Jackson) popped up at the cabin she used to share with Noah Solloway (Dominic West), and on the Dec. 6 episode Cole's brother Scotty Lockhart (Colin Donnell) pays her visit.

In a sneak-peek video of the upcoming installment, Alison is seen entering her apartment building when Scotty stops her. As previously recapped, Scotty hinted that he may be the father of Alison's baby.

Watch the preview for episode 10 below:

In the clip, Scotty asks Alison if he can come upstairs because he wants to talk to her. She refuses because her daughter is sleeping. Scotty instead asks her to sit down with him on a nearby bench.

In a second teaser, Scotty gets angry with Alison over the money Noah received for his book "Descent." The book, which is about his affair with Alison and also dishes dirt on the Lockhart family, helped boost Noah's career.

Scotty has been desperate to help his family out of a financial mess, and he tells Alison that Noah should give the Lockharts some of the money he made from the book.

In the final clip of Sunday's episode, Noah meets with a therapist (Marilyn Sanders, played by Cynthia Nixon) to talk about his troubled relationship with Alison. It seems like Noah is afraid of cheating again and admits to the therapist that he almost slept with his publicist Eden (Brooke Lyons).

According to Variety, Marilyn is a Manhattan-based couples therapist and will try and work with Noah and Alison to help them repair their relationship.
