'Orphan Black' Sneak Peek: Meet Helena, The Latest Clone (EXCLUSIVE PHOTOS/VIDEO)

At this point on "Orphan Black," we're used to seeing star Tatiana Maslany play multiple clones, so what's another one? We'd like to introduce you to Helena, who you briefly met at the end of Episode 3.

In Episode 3, the killer is finally revealed, and in Episode 4, "Effects Of External Conditions," Sarah steps up her hunt to track down the killer before her ruse as Beth is exposed and her relationship with her daughter Kira is destroyed forever.

In Episode 4, we get up-close and personal with Helena. She is the sixth clone, joining the previous five -- Sarah, Beth, Katja, Alison, and Cosima -- and with her scarred body, huge blonde hair and sideways sneer, we're sure she's a spitfire.

Episode 4 of "Orphan Black" airs on Saturday, April 20 at 9 p.m. on Space in Canada and BBC America in the U.S.

Check out the exclusive photos of the new clone below, and a video clip from Episode 4 above.
