After 22 episodes, it all comes down to the epic season three Supergirl finale. Who will be left standing after the final showdown between Team Supergirl and Reign? Obviously, Supergirl will be sticking around as the series has been renewed for a season four. However, it’s quite possible Sam (Odette Annable) won’t survive the season three finale. Annable’s been a great addition to the cast and I’m hoping the writers won’t kill her off quite yet.
Supergirl season three episode 23 is titled “Battles Lost and Won” and will air on June 18, 2018. Jesse Warn directed from a script by Robert Rovner and Jessica Queller.
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.
