Orphan Black is back! And we’re not just excited because it rhymes, though that helps. Season four will return to BBC America, and along with the new trailer comes a premiere date for the series: April 14 at 10 p.m. And if we know you (you binge-er), you’ll most certainly be following this season down the rabbit hole. In season four, Sarah Manning sets off to track down an elusive and mysterious ally tied to the clone who started it all: Beth Childs. Watch the newest trailer above; then, if you want, you can watch the first trailer and teaser below! Hey, what a neat-looking iris. Who could it possibly be?
