We’re getting close to the end of the season for Supergirl. Tonight’s episode, ‘Not Kansas’, is the 21st of the season with two more to go after. The CW has released an inside-the-episode video with executive producers Jessica Queller and Robert Rovner where they look at how this episode tackles one of the overall themes of the season: just how does Kara (Melissa Benoist) fit into this world, and where does she call home?
The season began with her reeling from having to send Mon-El (Chris Wood) away in order to save the planet. To cope with the pain, she shut down what she considered her human side — the Kara Danvers side — and focused on being Kryptonian and Supergirl. With the help of her friends and her adopted sister Alex, (Chyler Leigh), she got the balance back for the most part, but never truly returned to her secret identity life of having a job, etc.
In last week’s episode, Kara discovered that all most all of Argo City, the place she grew up, was saved from the destruction of Krypton. Her father’s technology harnessed black kryptonite into a shield that saved them, though he died in the process. But Kara also discovered that her mother Alura Zor-El (Erica Durance) was still alive. Kara returned to Earth to try and stop Reign/save Sam (Odette Annable), but it appears from the clips that they are successful and she decides to return to visit her mother. Whether this will be a long-term visit or not remains to be seen. But Kara tells Alex that when she was there, Argo felt like home.
Supergirl airs tonight at 8 p.m. ET on the CW.
