Via TVLine.com: "Imagine our surprise when we popped in the upcoming Justified Season 3 premiere (not-so-subtle brag intended) and Desmond Harrington appeared on the screen.
It turns out the Dexter star has a (formerly) top-secret guest spot on the FX drama’s season opener, and while we can’t say much, we can tell you this: Harrington’s character is a total badass boasting a deep Southern accent and ties to Jere Burns’ Wynn Duffy (who is back in a big way this winter). For now, the role is a one-off gig, but this is Justified, so you never know when someone might resurface."
