Melissa Benoist tells us that Kara isn’t in a good place when we rejoin her at the start of the new season, after she was forced to send Mon-El into space to save his life.
“She’s really fragile at the top of the season, but only people closest to her will see that, because she’s almost solidified on the exterior and is really trying to push down whatever pain she’s felt about losing Mon-El,” Benoist tells EW. “In turn, she has made this massive decision to say goodbye to her humanity and really embrace being an alien. We hear her say quite a bit in the first five episodes, ‘I’m not a human, I come from a different planet, so this doesn’t apply to me.'”
Chyler Leigh, who plays Alex, adds that Kara’s friends and family surround her to try to bring back the optimistic Kara they’ve come to know and love.
“All of the friends, Alex included, are trying to help her through it, but she’s just shutting a lot of people out, as a lot of us do in real life,” Chyler Leigh says. “Alex does everything that she can to give space, but it comes to a head pretty quickly just because Alex is obviously very honest, and the two of them have such a great and supportive relationship.”
Kara also has her Kryptonian heritage to turn to, and with the introduction of Erica Durance to the cast, taking over the role of Alura from Laura Benanti, fans can expect to see more of Kara’s birth mother in Season 3.
“It is different,” Benoist says of the new dynamic. “I loved Laura Benanti, but Erica brings something really fun to it. I’ve only had a few things with her so far in hologram, and we’ll see her more often. That’s always a really touching experience for Kara, to be able to talk to her in any shape or form, so we’ll definitely see more of that.”
