There's lots of potential trouble with the cartel and the Snells, but after watching the finale, I was also curious about some of the lesser enemies-in-the-making we've met along the way. What's going to happen to the preacher? Did he really almost kill his kid?
Mundy: I think in that moment he went planning to baptize the kid, but I think there was a moment where the other questions went through his mind. It's a battle for his faith right there, whether or not he's going to keep believing and hoping. The length of time with the baby, which is excruciatingly long, is his internal fight. I don't know when he's going to show back up in our life, but he's definitely going to show back up. The thing we really like about that character is that even though he's a person of faith, there's a real blue-collar, not-as-super-preachy quality to him. He would throw a punch at Marty as easily as he would quote scripture.
What about Rachel? When she bailed, was that her getting written off the show, or will she return?
Mundy: She was one of the only people who wasn't privy to Marty's secrets. And now, with the money and her understanding of what's going on, she has leverage and power over him. She'll definitely come back into our world. What we really love about her character is she seems so authentically of the place. We always thought of the Byrde family as an invasive species on that place. Rachel's not a criminal like the Langmores, but we want her to extract whatever she wants from the situation after the Byrdes have messed with her life so much.
