BBC America has released a brief new teaser for their upcoming season of "Orphan Black."

In the show's usual cryptic fashion, the Season 4 teaser doesn't really reveal much -- but it does raise some intrigue...

In addition to releasing the promo, the "Orphan Black" showrunners announced to EW that they'll be adding a new clone to the cast this season, named M.K.

"Sarah is meeting a clone who has got more answers than she does, and yet she’s a slippery character," said writer Graeme Manson on the latest addition.

Writer John Fawcett added, "And very elusive. And quite highly skilled and very smart. And it is interesting as Sarah tries to interact with this character who is almost kind of like a Deep Throat kind of character. What’s very cool about it is this is a clone who has been self-aware for some time."

Airing on BBC America -- now under the AMC Networks umbrella -- and the Space Channel in Canada, "Orphan Black" Season 4 promises the return of stars Tatiana Maslany, Jordan Gavaris, Maria Doyle Kennedy, Kristian Bruun, Kevin Hanchard, and Skyler Wexler, among many others.

"Orphan Black" Season 4 is set to debut in April 2016.
