FLYING SOLO.

Kara Danvers (Melissa Benoist) deals with the loss of Mon-El by focusing her energy on being Supergirl and protecting National City.

Lena Luthor (Katie McGrath) tries to make up for her past mistake with the Daxum Queen by hosting a tribute to the Girl of Steel.

With a statue of Supergirl.

But something goes horribly wrong.

It’s at Supergirl Appreciation Day that we meet Samantha Arias (Odette Annable) who was sent to Earth in a pod by Krypton villains and will become world killer Reign.

Sam and young Supergirl fan Ruby (played by Jacob Tremblay’s sister Emma).
