Delphine's fate in "Orphan Black" is not sealed yet and while all the signs point to her being a goner, fans can still look forward to Cosima's ex-girlfriend in "Orphan Black" season 4.

During the sci-fi drama's WonderCon panel, showrunner Graeme Manson revealed that Delphine's worrying situation in the season 3 finale will play a huge role in the new season.

"Delphine had such a brave journey last year and for us as storytellers, what we're talking about right now is a mystery. It is a big part of season 4, what happened there," Manson said, via Variety.

Although it remains to be seen what really happened to Delphine, co-showrunner John Fawcett stated that Cosima will "try to come up with answers" in order to move on from this at the beginning of "Orphan Black" season 4.

In terms of what to expect in the new season overall, Fawcett teased that "Orphan Black" season 4 will remind them of the first season and will even revisit dangling plot threads from there.

"We wanted to get that feel of season 1 back, you don't know who the bad guy is," Fawcett said, adding that they will look further into the events prior to Beth going to the train tracks in season 1.

"Orphan Black" season 4 will also give viewers a good look at the clones' ever-changing relationship in the upcoming season.

Jordan Gavaris, who plays Felix in the BBC drama, revealed that "there's some friction" between his character and Sarah. The actor adds that Felix will have to re-think what Sarah and S mean to him.

"There's jealousy at play. He gets a lot of intimacy from Sarah and a lot of connection ... If he's not getting it from Sarah, maybe he's getting it from somewhere else," he explained.

Meanwhile, Donnie and Alison will try to adapt to the suburban life as well as having to be under the same roof with a pregnant Helena. Art, on the other hand, will still be deeply involved in the Clone Club come "Orphan Black" season 4.

"Orphan Black" season 4 premieres April 14 at 10 p.m. ET on BBC America. The network is also launching an aftershow for the series, titled "After the Black," which will be on right after the new episodes air.
