Orphan Black: Formalized, Complex and Costly

Events never really slow down for poor Sarah Manning. No sooner are she and Felix stuck trying to dispose of the body of Seth than Art arrives with news about the location of Mark. Once again, Art is put upon to bend the law and pretend he didn't see the body.

Art has often been an odd character. He has constantly helped Sarah even when she keeps away from information he needs to know. We finally get an admittedly not surprising answer for this in that he actually loved Beth and she phoned him the night she died. It's a nice little bit of development although one might argue that this information could have been revealed earlier. It does at least mean that Sarah and Art are closer now.

Mark himself gets developed much more than previous episode . It seems that he was a Castor mole, sent to spy on Heinrich, in much the same way as Paul was sent to spy on Dyad. He tries searching for Heinrich's old samples but has no luck. Ultimately, Sarah's search has alerted the Prolethians and Heinrich's wife shoots and kills Mark. Gracie was apparently brought back into the fold. It is interesting seeing Gracie understand what she has let herself in for.

While Sarah and Art go after Mark, it is up to Cosima and Scott to examine the body of Seth for more DNA information. Cosima's removal of Seth's brain and Scott's reaction are pretty funny and a good example of the vein of dark humour that runs through the series. Their examinations also reveal that the Castor and Leda clones are actually siblings. This does of course make the scene where Rudy kissed Crystal pretty gross.

Castor Clone Rudy is back at the desert HQ where Helena is being held. He is seemingly back under Paul's command. It is also evident that the Castor clones see Dr Cody as some kind of mother. Paul forces him to search for Mark.

Alison is now selling drugs disguised in soap bars and gaining voters. So far her subplot seems to be disconnected from the main threads. It is bound to come together sooner or later. Hopefully it will be sooner.

Rachel is another Leda clone with issues. Doctor Nealon appears to be assisting her recovery. She is currently out of Dyad, but when she gets better there may be trouble ahead.
