Laura Vandervoort will reprise her role as Clark's Kryptonian cousin Kara in Smallville's 10th and final season, Michael Ausiello reports.
Vandervoort, who plays the extraterrestrial Lisa in ABC's V, will appear in just one episode of Smallville that tentatively scheduled to air in October.
Kara debuted in Season 7, when she awoke from an 18-year suspended animation. She hasn't been seen since Season 8, when she left on a mission to find Kandor, the capital city of Krypton rumored to exist somewhere in space.
Vandervoort is the second cast member from previous seasons revealed to be returning for the show's final lap: It was reported late last month that John Schneider will appear as Jonathan Kent in the season premiere and at least one other episode.
Smallville returns at 8 p.m. EST/PST Sept. 24 on The CW.
