Reign has been tearing through National City but she's not alone. Following the big reveal that she's not the only Worldkiller on Earth, the Girl of Steel has been on the hunt for the rest of them and she's going to tussle with Purity for the first time in tonight's episode of Supergirl! As you can see below, things don't go well when she comes face to face with her but what else is on the cards tonight?
"This an exciting episode where we see Supergirl face off with the second Worldkiller, Purity, played brilliantly by Krys Marshall," Supergirl executive producers Jessica Queller and Robert Rovner explain. "Purity is not what anyone expects and their showdown is full of surprises." As a result, it sounds like Kara may end up finding out some key clues about how she can defeat Reign when they meet again.
Apparently, we'll see another huge battle between Supergirl and Reign on the February 5th episode but the show will then go on hiatus for nine weeks with Legends of Tomorrow taking its timeslot.
