The Season 4 finale of “Orphan Black” is set to air soon. The 10th episode will showcase the huge confrontation between the sisterhood and the Neolution group.

Spoiler alert! This article contains “Orphan Black” season 4 spoilers. Read on if you would like to know what happens next before the new episode airs.

In the previous episode, two characters, namely Helena and Delphine (Evelyne Brochu), returned. Fans were excited to see Helena arrive just in time to thwart Neolution’s evil plan. Also, it turned out that Delphine is actually alive, but is still kept in a secret location.

ComicBookMovie writes that more of Helena is expected to be featured in Season 4, Episode 10, titled, “From Dancing Mice to Psychopaths.” She will continue giving help with the objective of stopping Neolution and Evie Cho (JessalynWanlim).

The final episode will feature an unlikely alliance between Sarah Manning (Tatiana Maslany) and Rachel Duncan. The two clone characters have not been in good terms since Season 3, but need to forget their differences in the meantime and work together to finally put an end to Neolution.

Previously, Susan Duncan (Rosemary Dunsmore) was displaced, causing Sarah to be placed under the control of the new boss. Rachel also had the same experience, which gave them an opportunity to bond and collaborate. They will most likely succeed in their plan, which will eventually improve their relationship. Rachel will also get the opportunity of getting more details about the other sisters.

In the promo video for the Season finale, Rachel was presented having visions of a mysterious man. She was shown meeting with Sarah to caution her that Evie Cho is going after her. They are only a short distance away from the enemy, and Alison Steadman (Kendall Malone) is tempted to reveal Sarah’s location. Subsequently, Alison will share vital information when Duko (Gord Rand) talks to a Neolution inmate and threatens Donnie (Kristian Bruun). Duko will believe that Sarah and Mrs. S (Maria Doyle Kennedy) have no plans, but in reality, they intend to bring him out and capture him.

Sarah, Rachel and Felix (Jordan Gavaris) will be reunited with a project Castor male clone. Adele (Lauren Hammersley) also discovers that Alison and Sarah are twins, although she will have doubts.

“Orphan Black” Season 4 Episode 10 will air on June 16 on BBC America. It also airs on Syfy in Australia.
