FX's 'Justified' Season 6 Spoilers: Will Timothy Olyphant, Walton Goggins, Jeff Fahey Discover Ava's "Dark Past?" [WATCH]

Based on the popular crime novels by the late author Elmore Leonard, the final Season 6 season of Justified continues on FX. Before their inevitable showdown, will Boyd Crowder (Walton Goggins), Raylan Givens (Timothy Olyphant), and Zachariah (Jeff Fahey) discover Ava (Joelle Carter)'s "hidden past?"

In our previous recap, Raylan discovered Avery Markham (Sam Elliott) was planning to legalize his weed business, while stealing property to grow it. After being humiliated by Markham, Boyd plans on stealing Avery's idea and robbing his money. Ava had a nervous breakdown after spending the entire day with Katherine Hale (Mary Steenburgen), whose suspicious of how she was released from prison.

In our recent recap, Ava unexpectedly rekindled her past romance with Raylan and kissed him. Elsewhere, Boyd met with Ava's uncle, Zachariah (Fahey) because he needs help breaking into Markham's vault. With his knowledge of explosives, Zachariah will help out Boyd for the money, even though they don't like each other.

In an interview with with Yahoo TV, showrunner Graham Yost teases Zachariah's involvement with Boyd, "The only thing I will tease is that we had one sort of ending in mind for him, and that changed because Jeff was doing such great work. It was just a huge get, getting Jeff Fahey to be in the show. You'll see a scene in the next episode between Ava and Zachariah that is really tremendous."

In an interview with Variety, Carter discusses her scene with Fahey, "I get to act with Mr. Fahey. He's remarkable. They brought this character into the Justified world and I told the writers, 'Let's not just make it a scene, let's dig into Ava's history because we know nothing about this woman besides she shot her husband at the dinner table.' So a little bit of Ava's past comes out."
