Orphan Black: Helena makes a deadly songesha in new season 5 clip 

world — when it comes to a show about clones, déjà vu comes with the territory — but a new clip from the show’s fifth and final season gives it a deadly new twist.

In the scene, released Wednesday by BBC America, Helena (Tatiana Maslany) brings a knife into a church, walks up to a sole parishioner sitting in a pew, and plunges it into her back.

It’s a swift sneak attack, but what happens next is even more surprising: as the woman collapses to the ground, we see her face… and she’s a Leda clone, with the same face as Beth, Sarah, Helena, Alison, Cosima, and all the others we’ve met over the years.

When this scene is happening is unclear — it’s hard to tell if Helena is still pregnant with her twins — but the time period is far from the only question it raises. The look of shock on Helena’s face indicates she didn’t know this woman was a clone. So, who is she? Why was she there? And who did Helena think she was there to attack?

Series co-creator Graeme Manson previously told EW that the heart of this final season will be “wrapping up our sisters,” but left room for the potential for meeting more

— “perhaps there might be a little squeak of room for one more clone.”

“I think this season is really about freedom,” he added. “It’s the final season and the clone sisters have to be all-in. … So, it’s a year with a lot of the usual 

 hijinks, but also, it’s a very, very, very important year for the relationship and the bonding and the freedom to move forward for the sisters.”
