Fans of Orphan Black know what a complex world it exists in, so it’s going to be fascinating to see how everything is resolved (or not) in the series’ fifth and final season.
A quick recap: when we last left the Leda clone sestras (all played by Emmy winner Tatiana Maslany), Sarah was badly wounded on the island after a bloody showdown with Rachel, who had taken charge of human cloning movement Neolution.
A deathly ill Cosima reunited with Delphine (Evelyne Brochu), Alison and Donnie (Kristian Bruun) were seeking refuge with Helena in the wilderness, and Mrs S (Maria Doyle Kennedy) and Kira (Skyler Wexler) were being held hostage by Rachel’s offsider, Ferdinand (James Frain).
With so many questions and only 10 episodes to answer them, here’s what we’re desperate to find out.
Who or what exactly is P.T. Westmorland?

What is the exact nature of the Neolution creator? Source: SBS
We know he wrote the bible of cloning, On the Science of Neolution, in 1872 and founded Neolution as “a secret scientific society” based on Darwinism and “early eugenical thought”. At this year’s television festival PaleyFest, Orphan Black co-creator Graeme Manson called Westmorland “the most evil, patriarchal figure… and kind of like a Doctor Moreau”. The show has referenced HG Wells’ The Island of Dr. Moreau, so does that mean we’ll be seeing some of his monstrous clones? And what exactly is Westmorland’s plan for humanity?
Then there’s a flash of a plaque in a trailer for the final season that reads “P.T. Westmorland & Sir Arthur Conan Doyle 1894.” What is his connection with the famed author? One thing’s for sure, the show’s creators say we’ll have to wait until sometime after the season premiere to finally meet the puppet master.
Could Rachel reign as Neolution’s villain supreme?

Her chilling announcement of the resumption of human cloning in the season four finale indicates as much: “Clones are farmed and monitored lab animals. If we want to know if our lab rats’ tails will grow back, we damn well will cut them off!”
Has Helena turned bad again?

Who’s going to die?

The stakes are higher than ever and each clone sestra would die for the other (probably not Rachel, though). The chronically ill Cosima has been on shaky ground for some time and Helena will do anything to protect her babies, as will Sarah for Kira. Much of this question will hinge on if a cure for the clones’ defective gene can be found.
The trailer also shows a photograph of Kira being burned, though that would be a very dark path, even for this show, to take. Whatever happens, we’re going to need to keep the tissues handy. “You’re going to be crying,” says Manson.
Is this really the end?

Will Sarah ever find peace? Source: SBS
Even if - and it’s still an if - we do get closure on the clone conspiracy, how each clone and character will find peace is a big part of the puzzle, especially for Sarah, who has been the hunted and the hunter throughout the story. And, promises Manson, there will fittingly be a twist in the tale.
“There’s this great open question about their hearts and their future and the strength of the bond of the sisterhood, everything they’ve gone through,” he says. “So, I think we do want to kind of have a sense of the future, of something moving forward when we get to the end of it. But again there’s a twist on that, and hopefully you’ll enjoy it through your tears.”
