Liz Keen won’t just be dealing with legal issues when The Blacklist returns.EW has learned exclusively that Revenge alum Margarita Levieva will reprise her role as Blacklister Gina Zanetakos.

Red (James Spader) then informed Liz of Zanetakos, an assassin who engaged in corporate espionage and terrorism, who was also Tom’s lover. Unlike the fate of most Blacklisters, Gina wasn’t killed, but offered a deal by the feds in exchange for her testimony.

When Gina returns in an episode slated for early February, the sultry jack-of-all-trades criminal will shake things up between Liz and Tom.

The Blacklist returns Thursday, Jan. 7 at 9 p.m. ET on NBC.
