Laura Vandervoort will be returning to Smallville for one last episode during the final season. Vandervoort will again play Kara Zor-El, cousin to Tom Welling’s Clark Kent and the would-be Supergirl, last seen in the series’ eighth season heading off in search of the Kryptonian city of Kandor.
We previously reported that John Schneider would also be returning for an episode or two. Who else will make a return for the final season? (We’re looking at you, Rosenbaum.)
