‘Orphan Black’ Season 4 Spoilers: Sarah’s New Clone Revealed; Is She A Friend Or Foe?

The “Orphan Black” clone club will only get bigger Season 4. The BBC America drama will show another one of Sarah’s (Tatiana Maslany) clones, but this one will be a little different. She’ll already know everything about her sisters.

Entertainment Weekly revealed that M.K. (Maslany) will be the new “seestra” in April. “She comes out of the shadows and for the first time we’re meeting someone who knows more than us,” executive producer Graeme Manson told EW. “Sarah is meeting a clone who has got more answers than she does, and yet she’s a slippery character.”

Last time the show introduced a self-aware sister, it was Rachel (Maslany). The cold-hearted clone has tortured her sisters, but it doesn’t sound like M.K. is quite that evil. She won’t be tracking down her sisters. She’ll be running from them. It seems M.K., who wears a sheep mask, is more of a neutral clone, rather than good or evil.

“She’s very paranoid,” executive producer John Fawcett added. “She’s very security conscious. She knows more than Sarah does so she knows how dangerous the whole thing is. She’s purposefully avoided contact with the sisters to keep herself safe, and Sarah is now trying to draw her out of the shadows and trying to utilize the information that she has so that Sarah can follow her own mystery and fill in the blanks and protect Alison and protect Cosima from Neolution. But this girl is very unwilling.”

However, M.K. just might have ties to Beth Childs (Maslany). Sarah will be trying to learn more about the dead detective in Season 4. The season’s synopsis revealed that Sarah will “track down an elusive and mysterious ally tied to the clone who started it all — Beth Childs.” M.K. certainly seems to fit that description, but of course, it wouldn’t be surprising if the drama introduced a few other enigmatic characters.

M.K. probably won't be the only new clone on the block. Ari Millen will continue to portray the Project Castor clones, and he said that there is definitely a possibility that more clones will show up. He revealed to Buddy TV last month that the writers were being very cryptic about the subject. “All they’ll tell me, and this is typical of them and their sadistic, teasing nature, is, 'It’s a clone show. You never know. Don’t be surprised, but don’t get your hopes up,'” Millen said.

“Orphan Black” returns to BBC America in April 2016.
