We’ll tumble down the rabbit hole of Orphan Black Season 4 soon enough, but nothing wrong with an early start. Wonder at the land of Orphan Black’s latest 2016 teaser, as Sarah Manning goes literary, and we get a closer look at the mysterious new masked clone “MK.”

BBC America released a moody new Season 4 promo for Orphan Black, which still lacks an official date beyond April of 2016, but definitely looks to burn some things to the ground all the same. At the very least, there’s more hinting of a return to Beth Childs, clone who started it all, as Sarah says “The only way forward is to go back.”

So reads the first official synopsis:

Season four of the drama will see leader-of-the-pack, 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.

As to the rest of Orphan Black Season 4, we know that the return of “Neolution” will bring about a resurgence of the clone series’ early body horror tropes, while a past panel confirmed that Evelyne Brouchu’s Delphine is only “Orphan Black dead.” We’ll also see more of clone addition Krystal, get a bit more clarification on Kira’s mysterious abilities, and likely see a number of other character returns.

Stay tuned for the latest on Orphan Black Season 4 in 2016, and check out the teasers above and below.
