"Orphan Black" season 3 may be packed with more revelations as it seems that Felix is a clone too.

Executive producers Graeme Manson and John Fawcett hinted what the fans should watch out for in the return of "Orphan Black" next season. According to the two, the series will be telling a mysterious puzzle of Sarah Manning and her clones. Just before the second season ended, Project Castor was introduced, which is claimed to be part of the overall mystery.

The two also talked about the process of how they chose Mark and made him a clone, dropping the initial plans to kill him off. They also said that they received an immense pressure from the fans to turn Felix into a clone because of the character's popularity.

Executive Producer and Co-creator John Fawcett told TV Line: "I think that we probably thought that we would just cast someone new. That we would find just a new person. As the season kind of developed and we were trying to figure that out, we realized that that just wasn't going to be that satisfying. We started to really look inward at the assets we already had. Ari Millen was cast as Mark at the beginning of Season 2 and was sort of slated to die partway through the season. We just kept being mesmerized by the work that he was doing and kind of went s*** we can't kill this guy. And then we kind of went. Wait a second..." 

Meanwhile, the third season of "Orphan Black" is reported to come back on air in the spring of 2015. Moreover, the filming of the next season just started that will surely bring forth a lot of spoilers.

Renewing the show for another season by BBC is not surprising after the successful run of the first and second season of the series. Moreover, the series proved to be one of the most successful series in television and has garnered international awards. According to reports, 10 episodes have been confirmed so far and Tatiana Maslany will still play the main character with multiple clones.
