Orphan Black's Sarah has lost her orphan title, but her foster brother has not.

'Orphan Black' Season 4: Series Creator Teases Finale, When Will Sarah & Co Return?

The sestras have become Sarah's family over the last three seasons, and when season 4 begins, the clones will band together to dig into the past. Unfortunately, the girls' bond will leave Felix (Jordan Gavaris) feeling just a little left out.

"I think it's gonna be cool this season to explore the idea of blood ties and biology and how much that bonds and connects people," Gavaris told Deadline. "Sarah's not really an orphan anymore and it's going to be weird for [Felix] to be the only foster child."

Blood or no blood, clone or not, Felix shouldn't worry. There's no way Sarah will fall out of his life (death excluded), and it's safe to assume Felix will have a major part to play as the sestras work to chase down an old ally.

"The new season sees Sarah (Maslany) returning home from her Icelandic hideout to track down an elusive new ally tied to deceased clone Beth (Maslany), whose identity Sarah stole in the series' first episode," BBC America teased. "With the stakes higher than ever before, Sarah and her sisters band together to uncover the missing chapter of the clone conspiracy - following Beth's footsteps into a dangerous relationship with a potent enemy who holds the key to their survival."
