‘Supergirl’ Season 3 Episode 21 Preview and Photos: “Not Kansas”

The CW’s Supergirl season three episode 20 ended with Reign about to punch Supergirl just as Lena was ready to use Kryptonite to kill Reign and, unfortunately, Sam. Supergirl and Mon-El had just returned to Earth with a piece of Harun-El, which might be the only thing that can stop the Worldkiller, when Reign broke out of her cage.

Up next, season three episode 21 titled “Not Kansas” set to air on June 4, 2018. The episode was directed by Dermott Downs from a script by Gabriel Llanas and Anna Musky-Goldwyn.

The season three cast includes Melissa Benoist as Kara Danvers/Supergirl, Chyler Leigh as Alex Danvers, David Harewood as J’onn J’onzz, Jeremy Jordan as Winn Schott, Mehcad Brooks as James Olsen, Katie McGrath as Lena Luthor, Chris Wood as Mon-El of Daxam, and Odette Annable as Samantha Arias/Reign. The series is executive produced by Greg Berlanti, Sarah Schechter, Robert Rovner, and Jessica Queller.

The “Not Kansas” Plot: KARA CONSIDERS A MAJOR LIFE CHANGE – Kara (Melissa Benoist) makes a major life decision. Meanwhile, J’onn (David Harewood) finds out that special DEO-caliber guns have hit the streets of National City.
