: Season 3 Trailer Shows Project Castor in Full Swing (VIDEO)

\'s new season shows the clones of Project Leda working together to fight against the threat of Project Castor as they continue to learn what they really are.

At the end of season 2, we saw that one of the clones from Project Castor (all played by Ari Millen) had kidnapped Helena (Tatiana Maslany). In the season 3 trailer, it seems like Mrs. S (Maria Doyle Kennedy) may have had something to do with it.

"You betrayed my sister," Sarah accuses Mrs. S, who replies that she "made a wartime decision."

Potentially in more danger than ever, Cosima says that she and her sisters (all played by Maslany) "can\'t rely on anybody but ourselves," and one of the Project Castor clones tells Sarah to "count your sisters."

In addition to playing the Prolethean Mark Rollins, whom we saw get hitched to Gracie (Zoé de Grand\'Maison) at the end of season 2, Millen will also portray clones Rudy, Seth and Miller.

The new season will also host Justin Chatwin, James Frain and Ksenia Solo in guest-starring roles.
