Sarah and Delphine team up to battle the neolutionists, family ties are strained and remade, and our clone hosts try to pick up the pieces after Orphan Black's shocking Season 3 finale.  Then, Hanna and Emma welcome back the father of modern cloning, Dr. Brian Chair, for a reconciliatitory chat. But when things go south and Dr. Chair reveals the ability to morph into a velociraptor, clone sister/escape artist/friend Blake Pastrydough appears to vomit up some help.

Delphine goes full Single White Female on Shay, the Castor mole isn't who we expect, and Hanna and Emma explain what happens when our beloved Orphans head across the pond. Then, our clone hosts are joined by Dr. Carmen Blade, CEO of the Agnes Corporation, who thinks we all need clone cell lines of our own. She explains how Hanna and Emma's signature characteristics are actually a product of board-driven decision making. Thank you, Carrot Top!

Rachel is back, and she looks GOOD. Doctor Coady is unkillable, it turns out, and the Hendrix household gets another new member. Welcome Helena, you baby ox, you. Then, world-renowned cryptographer Johnny Taiwan joins Emma and Hanna to explain the science of cracking codes, and correctly guesses all of our email passwords. You have to hear it to believe it.

Cosima and Alison pull a switcheroo over some much needed pee, Helena and Mrs. S finally come to blows, and as our clone hosts explain, a fierce hug heals all wounds. Then, Mark Wahlberg - or someone who sounds a whole lot like him - talks about his lifelong connection to the clone community: His mother Connie. He also reveals the ingredients in a Wahlburger and the plot to the upcoming Entourage movie. [Hint: They're all clones.]

Sarah and Helena hash it out in captivity, Cosima's new girlfriend might be sinister and Paul takes on the government – until it blows up in his face. Then Hanna and Emma talk with Dr. Johnny Von McNulty, the Jeremy Piven Chair of Television Science at Harvard College, Dublin. We think he's saying that Orphan Black's central metaphor is about how our increasing attempts at individuation are dooming us. Or not. But this much is clear: If Ayn Rand made a cartoon, it would be Gem and the...

Sarah and Helena are locked up together - but according to our clone hosts, they're still so far apart. Cosima has a hot date and Gracie's gone full CW. Then, in the event that our clones ever get locked up in a vaguely Middle Eastern prison, parkour expert/escape artist/friend Blake Pastrydough demonstrates the techniques she's been perfecting for years.

Hanna and Emma explain how Mark survives a close-range bullet wound thanks to emergency clone surgery from Sarah, and they have supportive words for Cosima getting back in the dating game. Then the clones' least favorite sibling, Janet, comes on the show to explain how she's managed to have it all, despite living in a world of anti-clone prejudice. Sister-clone dynamics are complicated.

The girl and boy clones are related, Mark bites it in a cornfield, Allison has fully broken bad, and clone sisters Emma and Hanna are here to explain it all. Then, Peabody Award-winning journalist Brooke Gladstone comes onto Duplicast to ask our hosts the hard questions about their origins and the mysterious organization that monitors their every move.

Hanna and Emma puzzle out Orphan Black's action-packed second episode: Paul is back with a vengeance, Helena's getting waterboarded in the desert and Donnie grows some stones. And we'll finally meet Emma's monitor, Mark! We'll learn all the special skills and attention to detail it takes to successfully monitor not only a clone, but a clone who's a friend. A really close friend.

Our clone-hosts Emma and Hannah are back from hibernation and ready to relive the glory of the Orphan Black season premiere. Rachel is alive? Male clones are whack? What is the deal with Helsinki? And in a special report from the field, Emma sheds a light on the life of a military contractor recovering from a severe brainwashing.

Twin clones Hanna Bingham and Emma Drexler prepare for the return of the BBC America show Orphan Black with a frank conversation about ownership over their own bodies. Then they moderate a fierce - and at times baffling - debate between Minister Cooper Gray and Epigeneticist Myron Benjamin about the ethical quandaries of cloning.

In the inaugural episode of Duplicast, twin clones Hanna Bingham and Emma Drexler tell us why the BBC America show Orphan Black means so much to them. First, they catch us up on where we left off, preparing us for the new season on April 18. Then things get emotional when they're joined by the father of modern cloning genetics, Dr. Brian Chair, who brings with him some shocking revelations.
