Carlos Bernard gives "devastating performance." The description sounds a bit like a middle road between seasons 1-4 Tony Almeida and season 7 Tony.
This is taken from an interview from Burn Notice series creator Matt Nix. The interview was found at

Could you also talk upcoming guest stars that you have lined up?
Matt Nix: [...]the guy who played Tony Almeida on 24. I'm completely blanking on his name. In any case, he is in the episode after this week's episode and he is playing a bad guy who Fiona has a real connection to. Oh sorry, Carlos Bernard, yes playing a bad guy who is really sort of only removed from the characters on the show by- under other circumstances he could have been one of the team, but he is willing to do certain things that they're not willing to do and that's a divide that they just can't cross. But he's a guy who's really committed to what he's doing, really cares about what he's doing.
It's a pretty devastating performance. He's pretty awesome. I'd say Garret and Carlos Bernard are the ones that are upcoming that really jump out at me right now.
