With Reign finding out that she’s not the only Worldkiller to have been sent to Earth from Krypton, Purity will make her appearance in tonight’s episode of “Supergirl”, but we’ll have to wait for her to go up against Kara in a few week’s time.

“This an exciting episode where we see Supergirl face off with the second Worldkiller, Purity, played brilliantly by Krys Marshall,” Supergirl bosses Jessica Queller and Robert Rovner tease of the February 5 hour. “Purity is not what anyone expects and their showdown is full of surprises.”

One surprise, in particular, may finally give Kara a clue as to how to defeat Reign.
