Orphan Black” returns for season three on April 18, and BBC America has released a new preview scene from the premiere in preparation for the hit sci-fi drama’s return.

In the clip, Sarah (Tatiana Maslany) comes face to face with the Project Castor clone Rudy — aka Scarface (Ari Millen) — who seems to know an unnerving amount about her and her family. Sarah doesn’t hesitate to threaten Rudy when he mentions her daughter Kira, but Rudy has a threat of his own, warning Sarah to “count your sisters.” Does he know about Helena’s capture at the end of last season, or is there another attack in store?

“Orphan Black” season three premieres Saturday, April 18 at 9 p.m. on BBC America.
