Last month, BBC America debuted the first footage from Season 2 of their hit series Orphan Black, which returns with the Season 2 Premiere April 19. Today, the network has released a new teaser, which shows numerous test tubes that represent the various clones of Sarah Manning (Tatiana Maslany), whose life is just someone else's experiment. The trailer will be shown during the annual Doctor Who Christmas Special on Wednesday night, but you can check it out for yourself right here.
