'Orphan Black' season 4 episode 9 spoilers: Helena is back; an unlikely clone team-up is made in 'The Mitigation of Competition'

“Orphan Black” Season 4 Episode 9 called “The Mitigation of Competition” showcases an unlikely pairing. The episode will feature Sarah Manning (Tatiana Maslany) who will be teaming up with Rachel Duncan (Tatiana Maslany).

Spoiler alert! This article contains “Orphan Black” spoilers. Read on if you would like to know what happens next before the new episode airs.

The previous episodes are proof that Sarah despises Rachel and vice versa. Ever since Season 3, they have been trying to take each other down. However, both of them also want to take down the Neolution group, which is what will compel them to work together.

In this episode they will finally talk and agree to put their differences aside to guarantee the fall of Evie Cho (Jessalyn Wanlim), who is the head of Neolution, writes TV.com.

It is speculated that their plans would be a success. There is a high chance that they would be able to fix their relationship so that Rachel would have a chance to know the other sisters more.

The episode’s trailer also shows Rachel having visions about an old mysterious man. In one scene, Rachel will have a meeting with Sarah to tell her that Evie Cho is hunting Sarah. Both of them have to work together to be one step ahead of Neolution’s leader, before Evie could put down Sarah.

Alison Steadman (Kendall Malone) will almost betray Sarah. This happens when Duko (Gord Rand) talked to a Neolution inmate to make threats to Donnie (Kristian Brunn). Alison eventually spilled information on Sarah’s location, which is under the comic book store. What Duko does not know is that Sarah and Mrs. S (Maria Doyle Kennedy) have a plan to lure him in and keep him hostage.

Also, Donnie’s life will continue to be in danger and Alison will do everything to keep him safe. Adele (Lauren Hammersley) will learn that Alison and Sarah are twins. However, it seems she will not believe it.

Viewers should also expect the return of Helena’s character. She will be providing some extent of comic relief for the episode. Her arrival would lead to difficult decision for Felix (Jordan Gavaris). Also, M.K. will be taken back with a warm welcome from the gang. She was very helpful in looking for Duko’s secret bank account and the Island based hideout of Susan.

“Orphan Black” airs on Thursday on BBC America. It also airs on Syfy in Australia.
