After a shocking throwback premiere episode of the fourth season of "Orphan Black," fans will be brought back to the current situation of Sarah, who, in the upcoming episode, will be making her way back home. She will still be looking for her future ally, M.K., while the Neolution still hunts her down.
The upcoming episode, titled "Transgressive Border Crossing," will drive the main character of the show back home after narrowly escaping the scientific organization's attack on her and on her child. She is also continuously on the lookout for M.K., one of her clones and future ally. It is also said that the mysterious M.K. will be able to help Sarah find the answers she has been looking for.
A short promo trailer for the upcoming episode was also released by BBC America. The clip shows Sarah hurriedly trying to get her daughter Kira out of the house in Iceland so they can leave. Siobhan is shown setting the house on fire, and probably because the Neolution is closing in on them.
Sarah is also seen asking Cosima about M.K., who replies and says that M.K. is the one who is always wearing a mask. The clip also shows the main character visiting Felix's apartment, talking something about mushrooms.
The clip also shows an unknown man with a worm coming out of his face, a big possibility that the Neolution is involved in it, while Siobahn warns Sarah that anything can happen now since there is a war going on. Lastly, a man is seen asking Sarah who she is, grabbing her hoodie so he can see her face.
"Orphan Black" season 4 episode 2, "Transgressive Border Crossing," will be aired on Thursday, April 21, at 10 p.m. on BBC America.
