Get ready to say good-bye to Tatiana, Tatiana, Tatiana, Tatiana, and Tatiana (give or take a few Tatianas). BBC America has renewed Orphan Black for a fifth and final season; the fourth season finale airs tonight. The series, which centers on a group of clones all played by Tatiana Maslany, launched the actress into wide critical acclaim, earning her an Emmy nomination and two Critics’ Choice awards in the process. Creators John Fawcett and Graeme Mason said in a statement that the ten-episode final season will “deliver an epic conclusion to the tale of Sarah and her clone sisters.” Let’s hope that “epic” means “full of dance parties.”
