'The Affair' season 3 air date, news & update: Maura Tierney says Helen will make bad decisions

"The Affair" season 3 will debut this weekend and star Maura Tierney said that viewers should prepare for a darker and more dramatic new chapter for the Showtime drama.

The third season, which will pick up three years after the highly emotional plot twist in the season 2 finale, will see the characters' complicated relationships getting even more complex. The premiere episode will reportedly see Noah (Dominic West) getting out of jail and moving in with his sister, to be played by Jennifer Esposito.

"This season is all about Noah," Tierney, who plays Helen, Noah's ex-wife, recently told the New York Daily News. "As the season progresses, there are more and more flashbacks. His journey in prison gets revealed towards the end of the season," she added.

In "The Affair" season 3, viewers will reportedly find Noah depressed and broke, despite his novel having made him famous. To make ends meet, he teaches a college writing class, where he meets a new love interest, Irène Jacob (Juliette Le Gal). According to the New York Daily News, this new character will have her own mysterious back story.

"It's about our darker impulses as humans and what happens if we follow them," Tierney said about the upcoming season.

In a chat with The Boston Globe, Tierney also spoke about her own character, hinting that Helen is bound to make a mess of things in season 3. "In her desire to have Noah back, she makes a lot of really poor choices," the actress said.

This is despite Helen having a new boyfriend, Vic (Omar Metwally), a doctor who lives in the basement of her brownstone apartment. According to Tierney, Helen will jeopardize this new relationship in her attempt to get info on Noah.

"She becomes really desperate and I think makes some very poor choices in regards to sex," she said. "We'll be seeing her use sex almost in a mercenary way, and that's very ugly," she continued.

"The Affair" season 3 premieres Sunday, Nov. 20, at 10 p.m. EST on Showtime.
