After a successful run, sci-fi thriller "Orphan Black" will finally be ending after Season 5 while its cast and producers tease the fans of what to expect in the final season.  

Actress Tatiana Maslany, who plays the roles of the different clones, finally earned her first Emmy's last week after gaining the Award for Outstanding Lead Actress in a Drama Series.

According to Christian Daily, during the red carpet for the awards night, Maslany revealed that some of the clones may probably have unhappy endings in the final season.

In Season 4, viewers saw some of the clones going to very dark paths. Maslany said the clones are going to have different endings while there will be few who will experience happiness.

In the same interview, the actress also revealed some of her favorite clones. She revealed that she likes Helena and Allison because they allowed her to do "more bizarre stuff".

Game & Guide reported that showrunners Graeme Manso and Jordan Gavarin also teased some information about the final season. Manson revealed that in the final season there will be a "new branch of contemporary science."

He added that they are looking into the topic of longevity and life extension as it is the very interesting field in science today. Gavaris also said that there will be no new clones in the final season. But he teased that there will be never-before-seen genetic copies.

As of writing, there is still no final date for the show's return.
