We already knew Aquaman was returning to Smallville in an upcoming episode, as part of the show's big final season. But now we know he'll have company when he does, in the form of his wife.
EW.com's Michael Ausiello reports that longtime DC character Mera will be in the ninth episode of the season, which features Alan Ritchson as Aquaman once again. Mera will be played by Elena Satine (Melrose Place) and yes, Aquaman and Mera are married on the series. My guess is this might be influential to Clark, as he ponders where his future with Lois could go.
Smallville star Tom Welling will direct the episode, called "Patriot," which will also feature the debut of Michael Hogan as Slade Wilson, AKA Deathstroke.
