Helena’s appearance may have been a surprise to us but it’s an even bigger surprise to Sarah who, last season, shot Helena dead. But miracles happen on Orphan Black or really, miraculous genes happen. Helena notices Sarah and slowly creeps toward her and it’s as scary as television can get. The framing in this episode is simultaneously beautiful and terrifying; that shot of the knife with Sarah in the background is shiver-inducing. And if Tatiana Maslany isn’t currently the best actress on television — look at the way her face contorts and the way her eyes convey pure fear — then I don’t know who is.
But Helena doesn’t want to hurt Sarah; she just wants help and soon she grabs Sarah in a hug, falling down on her, both of them upset, bleeding, and crying. They are clones, yes, but they have a stronger bond: they are twins — maybe half-human, maybe half-god twins — and they are always going to be connected, and they are always going to need each other in some way or another.
