The fourth season finale was a little bit underwhelming as far as I am concerned. Sure, it had the reunion of Cosima and Delphine and set the stage for season five, which will be
Orphan Black's last but it all felt somewhat anticlimactic to me. We all know that Sarah isn't going to die and that Mrs. S is going to find a way to deal with Ferdinand once and for all. Shall we have at it?
Let's start with Helena because her role in this episode like much of the season was small. Helena is now back in her wooded hide away with the Hendrixes and as to be expected, Allison is not doing well with the adjustment. Donnie blames Helena's cooking and even without eating it or tasting it, I think that he's probably right. Helena just wants to help and even offers to kill Evie but Sarah and Mrs. S advise her to stay where she is for now. Awwww, I want more Helena. I am not pleased with the way that she has been sidelined this season.
Now to the meat of the matter so to speak. On the island, Cosima and Mommy Dearest are pleased that the fertilized egg has lead to a scientific breakthrough. Cosima gets online to tell Mrs. S, Sarah and Kira that at last, she's got a cure. The celebration doesn't last long because Cosima quickly finds that she's locked out of the system and that her connection to the outside world has been severed. This of course is Mommy Dearest's handy work. No way was so actually going to do anything for her Leda Clones when she can get busy making more clones.
Evie Chow has been handed her walking papers by Neolution by unwisely chooses to resist, pointing out that the current PR disaster is not her fault. It's quickly evident that Evie falsely believed that her contribution to Neolution was more important than it is. For her trouble, Evie has her implant activated by none other than Dr. Ian Van Lier, her mentor and now replacement. As the announcement of Dr. Ian Van Lier taking over the company goes public, he is recognized by none other that Crystal, who remembers him as the man who swooped in and saved Delphine after she had been shot.
Crystal thinks she is in the know and gets in contact with Felix, who pretends to be a secret agent. Crystal is no longer buying Felix's fake identity and so Felix has no choice but to bring her into clone club. Upon meeting Sarah however, Crystal is not convinced that she is a clone, pointing out that she is a ten while Sarah is a seven on her best day. Oh Crystal. Crystal the most empty headed clone to date is convinced that there's a battle going on between Estee Lauder and a “Swedish company” called Neolution. That's it, no clone club for Crystal ever.
Sarah then pretends to be Crystal and confronts Dr. Ian Van Lier at a press conference. Sarah and Mrs. S hold Lier at gunpoint around the corner and she realises that mommy dearest never had any intention of handing over the cure for Cosima. Back at the comic shop, Sarah decides to go after Cosima. When Mrs. S asks to come along, Sarah says that has to do this alone. As the only one who is immune, if she doesn't get the cure to Cosima, she's destined to watch all of her sisters die. It's quite a statement and makes a massive impact.
While Sarah figures out how to get Ira to arrange for her to head to the island, Rachel is busy making big moves. What? You thought that Rachel would remain on team good? She's far too ambitious for that. After some sexy times with Ferdinand, Rachel meets with the board and suggests that they move the corporation someplace where they will absolutely own all of the clones they create, allowing them to place implants inside each of them. Rachel adds, “If we want to know if our lab rats’ tails will grow back, we damn well will cut them off and see". Damn, Rachel is cold.
With the boards support, Rachel heads to the island to confront Mommy Dearest. Susan feels that Rachel is in over her head and has betrayed all of the Leda Clones as well as herself. Rachel however cannot be talked down and believes that she is fulfilling her destiny to follow Susan. When Rachel gets a vision of a swan in her eye, she grabs a knife and attacks Mommy Dearest.
