This latest sneak peek is leaving enough breadcrumbs for fans to fall further down the rabbit hole with their own favorite 'sestras'. Prepare yourself. This is going to be one hell of a ride.

When Orphan Black Season 4 debuts this spring, heroine Sarah Manning sets off to track down an elusive and mysterious ally tied to the clone who started it all - Beth Childs. She'll follow Beth's footsteps into a dangerous relationship with a potent new enemy, heading in a horrifying direction that could end the sisterhood and their lives forever. We only have less than four months left, with all-new episodes set to debut this April/

BBC AMERICA has also revealed new clone MK, the masked self-aware loner who has lurked unseen in the shadows of the conspiracy from the beginning. This new addition will finally be able to provide answers to the most haunting questions. What new truths will she reveal to the sisterhood and how will it change their lives? But more importantly, is she friend or foe..? We'll have to wait and find out later this week.
