Even as Orphan Black heads into its fourth season finale this very night, few had any doubt the #CloneClub would return for a fifth run in 2017. Well, there’s good news and bad, as while Space has officially renewed the sestras for their fifth year, Orphan Black Season 5 will officially close out the series.

Space and BBC-A confirmed as much early Thursday, setting a 10-episode Season 5 to close out Orphan Black at an undetermined date in 2017. Previously, showrunners John Fawcett and Graeme Manson had spoken to the likelihood of a five to six season run, while the duo said of today’s announcement:

We are excited to deliver an epic conclusion to the tale of Sarah and her clone sisters. The past four seasons have been a phenomenal adventure and we are eternally grateful to our loyal fans who have loved the twists and thrills of our weird little show. We are thankful to our partners at Temple Street, and to BBC AMERICA and Space for their support and giving us the opportunity to end on a high.

Adds BBC-A:

Orphan Black is a thrilling, genre-bending ride that has captured our fans’ imaginations and hearts like no other show. Our genius team of actors, writers and producers have, time after time, taken us to a place of awe, delight and utter shock and surprise. Tatiana has been and continues to be a complete revelation, hers is one of the most remarkable performances on television, and she is joined by an extraordinary cast. We can’t wait to take our incredibly passionate audience on one final gobsmacking clone adventure.

In the meantime, tonight will run the fourth season finale “From Dancing Mice to Psychopaths,” but should we be sad to disband #CloneClub after Season 5? Had the series come to its natural end?
