Polly Walker (Caprica, Rome) will guest star on SyFy’s Warehouse 13 when season 4.5 starts in April 2013.
Walker will play Charlotte Dupres, a “nemesis of the Warehouse Team” and will appear in five of the ten new episodes of the hit show.
With the season finale – spoilers ahead! – ending with Artie, who slowly turned into a villain over the course of the season, possibly becoming a good guy again after being stabbed by Claudia—the show is going to need a new injection of villains. Walker seems like a perfect choice.
