Trucco's character is Nate Ryan, the brother of recurring character Kenny Ryan (JR Bourne, pictured above right with Trucco). Nate is described as "street-smart, charismatic and slightly menacing." It's unknown exactly how long he'll appear on the ABC series, but it's expected to be a significant story arc.
The Revenge role is Trucco's second major guest stint this year. He previously booked a return to How I Met Your Mother in July, and appeared in five installments of the CBS comedy as Nick, Robin's (Cobie Smulders) boyfriend. His final episode, "Splitsville," aired November 12.
It's been a productive year for the talented actor. In addition to the guest appearances, he was also a series regular as Assistant District Attorney Justin Patrick on the USA original series Fairly Legal, which was cancelled by the network in November after two seasons. The role earned him a spot on our list of the 10 Most Underrated Actors and Actresses on television this summer.
