Tatiana Maslany returns as Sarah Manning (and a host of other clone characters) in the third Season 2 trailer for Orphan Black, which returns Saturday, April 19 on BBC America with "Nature Under Constraint and Vexed". After realizing that she is a clone in Season 1, Sarah's mission this season is to find out how many of her kind are out there, and who created them. We also see brief glimpses of Detective Art Bell (Kevin Hanchard), Felix (Jordan Gavaris) and Daniel (Matthew Bennett) before this sci-fi series returns in just a few short months.
