SyFy’s “Sanctuary” is back! Check out the synopsis and teaser for tonight’s ep, “End of Nights” Part 2 (Season 2, Ep 2):

Furious at being duped into a trap, Magnus (Amanda Tapping) takes on Kate (Agam Darshi), demanding information and complete access to her Cabal contacts. The Cabal’s true agenda is revealed and Magnus realizes that they are not only holding Ashley (Emilie Ullerup) as ransom to obtain complete control of the Sanctuary Network, but turning her into the ultimate weapon. Now transformed into a Super Abnormal with devastating powers, Ashley and her newly cloned fighters begin their onslaught, destroying Sanctuaries in cities around the world. Tesla (Jonathon Young) and Henry (Ryan Robbins) attempt to create a weapon that can stop the attacks…without killing Ashley. As the team prepares to defend the Sanctuary with Tesla’s new weapon, Magnus must come to the realization that they may not be able to stop the Cabal’s attacks without harming Ashley. She realizes she might have to choose between saving her only daughter, or losing the Sanctuary and all the lives and secrets within it.
