This week's Orphan Black was especially notable for introducing a new Leda clone, Crystal, who hit it off with Felix in an entertaining meet-cute. (Alas, her fate seems a bit more dismal.) This also brought about a fun storyline for Sarah, Cosima and Scott, who broke Rachel out of Dyad to translate Duncan's secret code. Meanwhile, Donnie and Helena hit it off, while the former got into trouble with Jason. "Ruthless in Purpose, and Insidious in Method" also ended with a pretty big reveal -- that is, Dr. Nealon swapped Rachel with Crystal in the final moments.
