To refresh your memory: Orphan Black is a show about seven (at least) clones, all played by one very talented actress named Tatiana Maslany. In the second season … well, it's sort of hard to tell from the fast cuts in this trailer. But there are still clones! And they all look alike! And it's very dramatic! You have a month to watch season one, if you didn't the first time around. Get on that.
