For so long, Rachel has seemed so weak.

She could barely move, barely speak; she didnt register as the threat she once was.

Nope, not even close.

This week, in the season four finale ofOrphan Black, Rachel makes her move.

She takes down Susan Duncan, she steals Cosimas cure, and she reunites with her favorite bottom Ferdinand.

But okay, here we go.

This week, Sarah travels to the neolutionist island after Cosima goes dark.

First Sara has to find out where Rachel was holed up and thats where things get a bit tricky.

Let me backtrack a bit.

This week we say goodbye to Evie Cho.

Evie is killed by the new head of BrightBorn who was a puppet of Rachel all along.

This new silver-haired boss turns off Evies neolutionist tech, summarily killing the woman responsible for shooting Delphine.

Goodbye Ms. Cho, you wont be missed.

With Evie gone, Rachel makes her grand play to rekindle the Dyad cloning project.

Unfortunately, to do this, she needs Cosimas successful clone virus cure.

It is so sad to watch Cos get so close and then have the rug pulled from under her.

Yes, Krystal makes her triumphant return this week and helps Sarah discover where Rachels island is.

Sara disguises herself as Krystal and corners the new CEO of Brightborn.

This CEO is the same dude that saved Delphine from being assassinated and nursed her back to health.

Its also a blast to see Tatiana Maslany play Krystal.

Its even more fun watching Maslany play Sarah playing Krystal.

But Maslanys triumph this week is with Rachel as the new wicked clone queen ascends her throne.

Well, almost all, as Helena and Alison are in hiding.

We do check in with them twice this week.

Guys, ball play and diarrhea, nothing but the best for you at Den of Geek.

Remember that hundred year old neolutionist text that has popped up from time to time?

So Rachel gets the big W in this finale but not all is lost.

For a moment it seems like it might be as Cosima is freezing and dying.

She was so close to the cure that dying now would have been the ultimate in pathos.

But it is not to be as the old man in question finds Cosima and brings her to Delphine.
