Prepare to find out how Lex Luthor (Jon Cryer) is connected to Red Daughter (Melissa Benoist).

“In some ways, I am relating to Supergirl, but it’s a Kasnian version of Supergirl, and it’s fun,” Cryer said about the scenes he shares with Benoist as Red Daughter. “It’s really fun to play with that relationship because it’s so different."
