Please tell me your hands haven’t been soaking in some gruesomely fecund jelly.—Dr. Marion Bowles

Orphan Black delivers a weaker episode than usual, but it includes a number of important developments, a big dose of farcical comedy—and Siobhan Sadler at her badass best.

Premise

We meet a new character who clearly outranks Leekie as the rehab gang runs amok on Family Day. We learn Kira’s significance, Siobhan cuts a deal, Rachel and Cosmina learn uncomfortable truths, and Dr. Ethan Duncan recovers some key data.

High Points

Donnie develops as a character; even his cluelessness as a monitor comes in handy.

Low Point

I laughed at the rehab scenes, but does anyone else find that Vic Abuse is getting old? That was last season’s shtick. Do something else with this character, or eliminate him entirely.

The Scores:

Originality: 3/6 in an episode which (inevitably) used the twins for Menaechmian comedy, did we also need Donnie to pull a Vincent Vega at the conclusion?

Effects: 6/6

Story: 5/6 The story felt more contrived than usual. They were forcing certain developments and comic shenanigans.

Acting: 6/6 My vote for Best Performance by Tatiana Maslany this week would be Sarah as Alison as Donnie, with Sarah losing track of who she’s supposed to be. Tatiana Maslany, however, knows exactly what she’s doing.

Emotional Response: 5/6

Production: 6/6 The music, mostly by Trevor Yuile, seems especially fitting this week.

Overall: 5/6 Are rehab facilities actually like this? Anyone?

In total, “Knowledge of Causes, and Secret Motion of Things” receives 36/42
