"Orphan Black" is taking us down the rabbit hole — but what we find on the other side looks to be a nightmarish Wonderland.

BBC America released a new teaser for season 4 of the sci-fi thriller drama, and as the show loves to do, it raises a ton of questions. Tatiana Maslany reads a selection from "Alice in Wonderful" in the voices of clones Sarah, Helena, Cosima, and Alison. And at the end, she says, "The only way to go forward is to go back" — over a reversed shot of Beth, the cop clone who jumped in front of a train way back in the pilot.
What does it all mean? Well, that's a question "Orphan Black" viewers are used to asking themselves on a weekly basis. Will season 4 feature flashbacks to Beth's life? Dig even deeper into the past of the clone experiment? Bring Beth back from the dead somehow?

"Orphan Black" season 4 is set to premiere sometime this spring.
