Sarah is about to find herself in a frightening situation when she receives a vicious threat on Orphan Black.

Creators 'Kicked The Shark' On 'Orphan Black?'

On Monday, a sneak peek was released on the Season 3 premiere episode when Sarah makes her way into a somewhat isolated room with Rudy who looks scarier than expected. It seems like the creepy man really wanted to see her though since he tells her that she's a "legend."

She obviously doesn't see him as anything worth her time, but that's about to change as the conversation continues. He says that she's made of the "good stuff" and wants to tell her more...but others can hear them.

'Orphan Black' Season 2 Chatter

Rudy asks Sarah to come closer so he can whisper what he needs to say, but naturally the tension is a bit more hesitant than that. Sarah pulls out her hard-core side by telling this guy that she kicked his brother in the face. As threatening as she might look, Rudy has an odd reaction to this- he laughs.

The man then brings up Diane and how certain people might not want to be trusted. Sarah only trusts her sisters, which causes more intensity. When Rudy brings up more members of the woman's family, he happens to mention Kira.

The sound of the child's name is what will really make Sarah angry- so angry that she gets up and threatens to kill Rudy if he ever comes near her family.

Before Sarah leaves the room, Rudy has one last thing to say to her: "Count your sisters."
