Yup, that's another new clone under that creepy sheep mask. This mysterious character goes by the equally mysterious moniker "M.K.," and it looks like she may have some of the answers Sarah's been seeking for so long. She's been "self-aware" for a long time, meaning she understands she's a clone, and co-creators Graeme Manson and John Fawcett describe her as "very elusive," "quite highly skilled," and "very smart" — but also "very paranoid" and "reluctant" to get involved.

While Orphan Black is sure to throw lots more twists and turns our way, its first big surprise is its release date. The series will premiere April 14 at 10/9c on BBC America, which is a Thursday. So if you've spent the past three years planning your Saturday nights around Clone Club, adjust your schedule accordingly.

Sarah, reluctantly return home from her Icelandic hideout to track down an elusive and mysterious ally tied to the clone who started it all — Beth Childs. Sarah will follow Beth's footsteps into a dangerous relationship with a potent new enemy, heading in a horrifying new direction. Under constant pressure to protect the sisterhood and keep everyone safe, Sarah's old habits begin to resurface. As the close-knit sisters are pulled in disparate directions, Sarah finds herself estranged from the loving relationships that changed her for the better.
