Supergirl

CW | 9:00 pm

Supergirl and Zor-El (Melissa Benoist, Jason Behr) return to National City, determined to put the trauma of the Phantom Zone behind them and enjoy the shared superhero life in the new episode "Welcome Back, Kara." Unfortunately, their efforts turn a mite too overzealous, inadvertently creating a whole new threat to the city. Chyler Leigh also stars.
