Episode 9 of Supergirl?s second season will be directed by Kevin Smith and will guest star his daughter Harley Quinn Smith. Harley posted a photo of her script on Instagram and got some mean comments about casting. Some people said she was only cast because her father was the director. ?Honestly, comments like that really bother me because it's like you're trying to demean my talent and personal capability,? She responded. ?Yes, obviously in this case my dad is directing the episode, but that doesn't mean that I couldn't have done it without him.? Supergirl airs on Mondays at 8PM on The CW.
