In the forthcoming final season premiere of Supergirl, "Rebirth," the Girl of Steel will face off against Lex Luthor again, and that may come at a high cost. Co-showrunner Jessica Queller revealed this will have consequences for Supergirl that will be the focus of the season's early episodes and lead into one last journey for her.
While speaking to EW, Queller stated that Supergirl "is going to really sacrifice her life and put her life on the line to save her friends and humanity." She continued, "That challenge, she's going to face her mortality in a way we've never done on the show," she continued. "That's really the focus of the first run of seven episodes. It's life or death stakes for Kara, and it's very introspective. So, all of the soul searching and taking stock of the past six years will happen in the beginning, and then she'll put it all into play in the second half."
Lex Luthor used the Obsidian platform to brainwash half of Earth's population into loving and following him no matter what. Supergirl will come to the conclusion that the only way to defeat Lex is to sacrifice herself.
