"Orphan Black" ended season three with a bit of hope, as Sarah Manning is finally reunited with her daughter Kira. But that does not mean things are about to go easy for the Clone Club. In any case, things are about to blow up, no thanks to the male clones — or at least one of them.

More details about the fourth season of "Orphan Black" have emerged, thanks largely to the recent PaleyFest where the show had a panel featuring the cast — lead actress Tatiana Maslany (who plays a wide array of clones), Kristian Bruun (Donnie Hendrix), Jordan Gavaris, (Fee Dawkins) and Maria Doyle Kennedy (Mrs. S) — and their executive producer Graeme Manson. Some pieces of news have already trickled online, especially about Delphine (Évelyne Brochu), who was last seen taking a seemingly deadly shot from an unknown source. Good news for her fans, she is going to survive to season four.

But while things are going to turn out fairly okay for Cosima's monitor, not so much for Mark Rollins, played by Ari Millen, who also incidentally plays all the other male clones. Mark had already been a pretty huge player in the last season but he will be a game-changer in the next. The panel hinted at how the character will put into play the biggest twist for season four.

Speaking of twists, Sarah's foster brother, Fee, will have his own thing going on in the upcoming season. With Sarah discovering so many of her family ties — from the original genetics to her many, many "sister" clones — the modern artist just might go looking for other ties.

Design&Trend quotes him, "I think it's gonna be cool this season to explore the idea of blood ties and biology and how much that bonds and connects people."

Asked to expound about it, actor Gavaris said he cannot at this point given they are also being kept in the dark about the plot.

"Orphan Black" is set to air in 2016. More news is expected as the new season starts filing. Stay tuned for updates.
