Where would their war end up?

Before the cast of the Canadian science fiction thriller television series, which was created by screenwriter Graeme Manson and directed by John Fawcett, join the panel at the Comic-Con on Friday, we have put together the details we have learned so far.

According to Manson, the upcoming "Orphan Black" season 5 "will be going back to that elemental Sarah versus Rachel nemesis dynamic," Entertainment Weekly revealed.

Manson further narrated that in order to make the series' plot and storyline or exciting, Krystal Goderich, the bubbly blonde beautician also portrayed by Maslany, is expected to return after appearing in season 3 and 4.

As with the male clones, the co-creator suggested that Ira (Ari Millen) will be reprising his role while teasing that the production team has "left a Castor or two out in the wind."

"There may be other 'Orphan Black' characters we've met over the past few seasons still in the wind that we would be very interested to somehow roll back into our story next year," he said about the "Orphan Black" season 5 spoilers that its followers can look forward to.

Meanwhile, back in April, Fawcett shared that the fifth season will already mark the end of the well-loved and widely-acclaimed sci-fi series.

"I think we want to wrap this story up by the end of season five," he told E! News.

However, he hinted about the possibility of still considering another season when he declared, "if there are still a lot of fans and a lot of desire to see this show after that, I think there would be some reinvention necessary or some kind of new spin."
