In the newly released trailer for the upcoming season of Supergirl, audiences can hear the titular heroine refer to her Kara Danvers persona as “a mistake.” The implication of this bombshell confession is that she no longer believes that she can blend in with the humans, and she’s no longer interested in trying to make it work. The revelation shocked audiences in attendance at San Diego Comic-Con, and Melissa Benoist subsequently took the stage to explain that her new attitude towards Kara primarily stems from the fallout of her decision to send Mon-El away from Earth at the end of Season 2, saying:
“I think for the first few seasons she’s kind of been drawn trying to balance Kara Danvers and Supergirl, the reporter, and the superhero, and figuring out her identity. And now where we pick up in Season 3 still is leaning very heavily on Supergirl. I think that’s how she’s coping with this grief of sending her boyfriend into a giant chasm in space.”
This decision won’t go over well with Supergirl‘s supporting players, and the rest of the show’s cast chimed in at the San Diego Comic-Con panel to explain that Kara’s choice to distance herself from humanity will instantly draw concern and suspicion among those she cares about. The core theme of Supergirl‘s third season is the question of what it means to be human and have humanity, and every single one of these characters (whether they hail from Earth or not) will be forced to answer that question through their approach to Kara’s struggle.
Supergirl will return to The CW this fall on October 9 at 8 p.m. EST.
