When you’re playing with as enjoyable a cast of supporting characters as the writers of “Justified,” you can spread the attention around.

In “The Devil You Know,” the episode of “Justified” that aired on FX tonight, the great supporting cast of lowlife bad guys — Dickie Bennett, Dewey Crowe and Devil, the Boyd Crowder subordinate who took a cast iron skillet to the puss a few weeks ago, all have plenty to do.

Dickie and Dewey get broken out of prison — well, Dewey comes along for the ride — when a group of crooks want Dickie to lead them to a cache of money that belonged to Dickie’s beloved late mama, Mags Bennett.

Meanwhile, Devil decides he’s going to rebel against Boyd Crowder (Walton Goggins), the series’ wild card and strong suit. Devil learns, the hard way, that crossing Boyd in favor of Quarles — the slick new out-of-town crime boss who wants to muscle in on Kentucky crime — is a bad idea.

I haven’t mentioned Raylan Givens, the U.S. marshal and central figure of the show. He’s seen here tonight doling out some justice with his federal-issue vehicle and visiting Loretta, the youngest and smartest of the Bennett clan that dominated the show’s second season.

There’s also a nice scene with the marshals and Limehouse, the leader of a black community and his own prosperous criminal organization.

“Justified” is having a lot of fun this season, setting up a new pack of bad guys and strengthening old favorites like Boyd. It’s a lot of fun to watch.
