The comedian revealed that Bob Sweeney aspires to be a lawman of Raylan's caliber, and that there are hints of a shady past.

"It's a guy that basically sorta wants to be Raylan Givens, but is not, which I think most men can relate to. He thinks he has a dark, mysterious, messed-up past, but there's hints that everybody already knows about it and doesn't care. I do get to do stuff that's a combination of, like, super funny and super funny violent. I'll leave it at that."

He also spoke about collaborating with Timothy Olyphant during their scenes together.

"There's just a lot of collaboration scene-to-scene. We'd talk in between scenes and go, 'Well, let's go try that.' Or we'd run a scene, and we'd go, 'Something's missing. This isn't necessary.' He's just very, very present and aware of what he's doing in a scene. It's kind of amazing."

The actor will return as Bob Sweeney sometime later in the season, although it isn't known how many episodes he will appear in. FX hasn't announced exactly when Season 4 of Justified will debut yet, so stay tuned.
