A lot of "Orphan Black" season 4 spoilers emerged from the PaleyFest New York. The cast of the clone-filled series led by Tatiana Maslany along with executive producer Graeme Manson were all there ready to serve up some details about what to expect in the upcoming season.

For starters, it was revealed that fans will see more of Ari Millen, who plays the role of Mark Rollins (who himself has a lot of clones) in the upcoming season. From what was hinted, he will be responsible for a big twist this year.

Meanwhile, the group teased the fate of Delphine, who was holding on for dear life when viewers last saw her. Fortunately, she isn't ready to bite the dust yet. Manson, who acknowledged fans for being invested in the story, teased (via IB Times) that wherever she was hit, "I don't think that's necessarily fatal."

It seems that Delphine will make it out alive but what of her relationship with Cosima? Maslany hinted that in "Orphan Black" season 4, fans will get a chance to get to know more about the character outside of her romance with Delphine – something the star herself is excited about.

On the other hand, cast member Jordan Gavaris also hinted that "Orphan Black" season 4 will deal with how and where biological connections start and end as far as how complicated things got for his character Felix and the situation the group is currently in.

He hinted (via Design & Trend) that the show could next "explore the idea of blood ties and biology and how much that bonds and connects people." The actor then explained what the new season will be for Felix considering that aspect. "Sarah's not really an orphan anymore and it's going to be weird for Felix to be the only foster child."

"Orphan Black" season 4 will premiere sometime next year.
