Following a terrific season finale of Justified - which wrapped up the Robert Quarles storyline, while teasing new ones for next year and also bringing the focus back to Raylan and his ruined relationship with Arlo - Alan Sepinwall of HitFix spoke to showrunner Graham Yost.

In the wide-ranging interview, the latter went into detail about various aspects of "Slaughterhouse," and also gave us an idea of what to expect on season four. To wit:

Will Limehouse return? "Yes. Given [Mykelti Williamson's] availability and all that, and how the stories are starting to shake out… I think Limehouse is a keeper. He just did great work, and it's a fun character."

What are the main questions that will drive the season? What's going to happen with Johnny, Limehouse, Boyd and Ava? What's going to happen between Raylan and Winona, once the baby is born? Do we want to do another bad guy of the year? Do we try and mix that up? Do we want to do one story? We've been thinking about [Elmore Leonard's] "Raylan" book, which came out this year, which is three stories: do we want to do that? Three four episode chunks rather than one big thing?"

What is the status of Natalie Zea, who signed on for a new Fox pilot? She'll appear in around three episodes of season for. Says Yost: "I would foresee seeing Winona in some way for the life of the series... We'll see where Winona's life goes: is she going to meet someone else, where is the baby going to live, is Raylan going to meet other people?"

Yost concluded that the theme of "betrayal" will likely play a key role going forward, especially as it pertains to Boyd, Johnny and Limehouse.
