Rudy (Ari Millen) and the male Castor clones seem to be causing major trouble for Dyad, and as a result, the very lives of Cosima, Helena, Alison and Sarah are hanging in the balance.
And it seems like even semi-trustworthy Mrs. S. is working against the clones -- can she be relied upon anymore?
(Watch trailer, above.)
