Wynonna Earp reconnects with Mercedes in exclusive episode preview

With only three episodes left in Wynonna Earp season 2, the tension and drama just keep building — and Friday’s episode continues that trend.

Last week, Dolls discovered the Gardner sisters’ secret: They were really Black Widows, and the real Gardner sisters were being held in their own basement without faces. One did not survive, and the other was barely hanging on when he found her.

Now, in an exclusive clip from episode 10, “I See a Darkness,” we learn Mercedes is the sister who survived. Wynonna visits her old friend in the hospital and vows to get retribution for what she’s gone through. Based on the fact that Widow Mercedes has come for Nicole, Wynonna might not be the only Earp ready to seek vengeance.

Be sure to watch the full clip above, and tune in Friday at 10 p.m. ET on Syfy.
