Tonight we are getting the third episode of Supergirl Season 3, and it involves J'onn J'onzz (David Harewood) going back to Mars. Executive producers Jessica Queller and Robert Rovner sat down for an inside look into the episode.
They talk about J'onn seeing his father, M'yrnn J'onzz (Carl Lumbly) and how amazing the two actors are working together. Like with Superman being the 'Last Son of Krypton', J'onn was the last Martian, then the last Green Martian — and now he's part of the last Green Martian family. Soon he may be the last Green Martian whose name starts with a J.
Continuing the theme of Fathers, Alex (Chlyer Leigh) and Maggie (Floriana Lima) are holding a bridal shower and Maggie's dad (Carlos Bernard) comes to the party. He, like his daughter, was a police detective. They're not on good terms, and Maggie hasn't spoken to her parents since her father threw her out when she came out at the age of 14.
Alex suggests to Maggie to use the shower as a reason to reach out to her family. Rovner talks about how the episode has parallel ground stories about people dealing with their fathers — one on Mars and one on Earth.
The CW has also released a fourth clip for the episode where J'onn tells Kara (Melissa Benoist) and Alex that he has to go to Mars.
Supergirl airs tonight at 8 p.m. ET on the CW.
