Orphan Black season 2, episode 8 “Variable and Full of Perturbation” airs tonight and Cosima will be dealing with her science while Felix and the gang deal with a whole new problem.

Last week on ‘Orphan Black’

Cal and Kira started going on the run, again, when he found out someone was able to hack his computer to spy on him. ELswhere, Sarah and Mrs. S. managed to get Ethan Duncan to hand over the information they need about the original genome and got Rachel to come to their side, firing Dr. Leekie in the process. However, he didn’t survive long as Donnie accidentally killed him in the final few minutes.

Back in suburbia, Alison managed to get Felix and Sarah to help out with her Vic situation, which ended in an unconscious Vic being framed for doing coke and Alison’s ass getting saved from being ratted out to Angela. Oh, and Alison revealed to Donnie that she’s a clone, in which scene she discovered he had no idea about what was going on ever since he started monitoring her.

This week, things get complicated.

And that’s just an understatement. Tonight we’ll witness a new character enter the lives of Felix and the gang, which means something way more complicated is going on. And Cosima’s illness is starting to take a worse toll than ever before. The synopsis reads:

A new player in the clone conspiracy turns up at Felix’s door, sending him into crisis mode. With Cosima running out of options, Sarah struggles with the decision to surrender a crucial piece of leverage and make a deal with DYAD.
