As any Orphan Black fan can tell you, Tatiana Maslany and Kristian Bruun have some of the best on-screen chemistry on television.
But what we really wanted to know was: Does that chemistry translate to real life?
So, in advance of Orphan Black's fourth-season premiere this Thursday (10 p.m. ET on Space and BBC America), we put Maslany and Bruun to the test to see how well they really know each other.
We asked them a series of personal questions to see if they could, er, clone each other's answers. (Get it?)
