The fourth season of "Orphan Black" could tackle the complicated love lives of the Leda clones when the series returns in 2016.

In the previous season, one of Tatiana Maslany's characters, Sarah, escaped to Ireland with her daughter Kira (Skyler Wexler) to break away from all the drama involving her sister and the chaos brought by the Castor clones. But the mother-daughter tandem is not alone, since Kira's father Cal (Michiel Huisman) joined them during their escape.

Could this mean that there is a chance for Sarah and Cal to get back together? But executive producer Graeme Manson mentioned during the 2015 PaleyFest in October that Sarah deserves a new love inspiration for season 4.

Aside from Sarah's possible love angles, fans should also look forward to seeing Cosima as a single woman in the upcoming season.

For the longest time, Cosima is in a relationship. But her girlfriend Delphine (Evelyne Brochu) was fatally wounded in the previous season. While there is no confirmation yet regarding Delphine's fate, Maslany said in an interview with Entertainment Weekly that she is excited to see how Cosima deals with being single.

"What I'm also interested in with Cosima is, outside of relationships, who is she? Because we have always seen her romantically linked to somebody... I'm interested in that because it is a thing that often women are paired with somebody, and that's how we define them," the Canadian actress shared.

Meanwhile, Ari Millen recently sat down with Buddy TV to discuss how he deals with working on multiple characters as the Leda's rival, the Castor clone.

Millen recalled that he had a hard time filming Seth's death scene, since the character died with his eyes wide open. He shared that the scene took an hour to finish because he could not help but blink during the filming.

The actor also revealed that his most favorite Castor role to play is Rudy, but there are more interesting stuff to look forward to for his other character Mark.

"Orphan Black" season 4 is slated to premiere in 2016.
