Rachel returns home to find Rosen dead, which she takes out on Sarah and Cosima. She also makes Paul an offer he can't refuse, even if he wanted to. In this new position, Paul decides to use Felix to help Rachel. Leekie, unlike Rachel, shows that his plans veer toward the truly scientific, he who provides Cosima and Delphine with some information about the clones' past. Feeling indebted to Helena for saving her from Rosen, Sarah decides to help Helena within the bounds of what Sarah believes is right. Helena may have thoughts of her own about what she wants to achieve. But she also provides both Art and Sarah with some information about Maggie Chen, which they in turn use to find out more about Rachel's past. Cal and Kira are still hiding out in Cal's motor-home, Kira who hints about Sarah's "sisters". And Henrik and Bonnie have Gracie confined for what she did regarding Helena, which Gracie may have to pay for in more ways than one if Helena is not retrieved. Written by Huggo

Did You Know?


In the bar where Helena (Tatiana Maslany) is drinking...Paul (Dylan Bruce) wonders if Mark (Ari Millen) was Special Forces or JTF2. The Joint Task Force 2 is an elite Canadian anti-terrorism unit garrisoned in the Toronto area. While JTF2 is not quite a secret, little information about it is released by the Canadian government.

In a brief shot of Helena at 10:43, we see someone other than Tatiana Maslany: presumably her stand-in, though no other clones are in this scene. See more »

Orphan Black continues the run of strong episodes with another episode intense and full of intrigue.
16 July 2015 | by See all my reviews

It seems like Dr. Leekie may not be such a bad guy after all. Rachel goes kind of crazy after the ending of last episode, so she suspends all research into the genetics of the clones until Sarah is found. But, Leekie goes behind her back to help Cosima and Delphine, and works with Sarah to find their origin.

Back to Rachel, she appoints Paul as her monitor. We learn more about the strange nature of her power. Paul seems to be in quite a pickle, caught between Rachel and Leekie.

Art interrogates Helena, but she escapes. This leads to Helena once again being the centerpiece of the intense final scene.
