Deputy U.S. Marshal Raylan Givens (Timothy Olyphant) has no shortage of old and new adversaries.
At the end of this week's episode, "Harlan Roulette," Raylan's pursuit of Wynn Duffy (Jere Burns) brought him face-to-face for the first time with his real nemesis, Detroit mob "star" Robert Quarles (Neal McDonough). The episode ended perfectly with Raylan snapping Quarles' photo and giving him a look that said, A. "You're strange," and B. "Should I be worried about you?"
