Supergirl will be bringing on a new cast member to play a younger version of Kara during flashbacks in season 3. Family has always been an important thing for Supergirl, although sometimes the ones closest to her are brought into harm's way because of her powers and the villains she faces. Meanwhile her sister, Alex, is usually at the heart of all that. Thanks to her job at the D.E.O Alex is often thrust into danger alongside Kara, but it typically manages to bring the sisters closer together when they have to work together.
Going into the third season, multiple characters will be facing big changes in the aftermath of the Supergirl season 2 finale. Kara will be facing some personal issues as she struggles to deal with her dual identities - and after the disappearance of her romantic interest Mon-El at the end of season 2, she begins to invest more time as Supergirl and less as Kara. The trailer for Supergirl season 3 has already provided a tease of what to expect, when that happens.
A younger version of Kara will also be appearing soon, during a flashback-heavy Supergirl season 3 episode. The flashbacks will show fans how Kara and Alex became so close as sisters, when Kara first arrived on Earth. EW is reporting that said episode is titled 'Midvale' and will see the Danver sisters travel to their hometown, in order to investigate a mystery that plagued said town when they were teenagers. Izabela Vidovic (The Fosters) will be playing a younger version of Kara in the episode, taking over from previous young Kara actor Malina Weissman (who now stars in Netflix's A Series of Unfortunate Events). Here's what Melissa Benoist told EW, with regard to what fans can expect from the episode:
“You’ll get to see, through the way they interact, how their relationship started when Kara first came to Earth, how it grew, how it became so close and why they’re so close nowadays.”
Now that we know that the Danver sisters will be returning home, we have to wonder what it is drawing them back there? If Kara is struggling to balance between her life as Kara Danvers and her costumed identity, perhaps a trip back to her family home could realign her thoughts and bring a balance to her life. It's clear that she'll be relying on her friends and family to get her through the internal struggles of being a superhero. Friendships will continue to grow, like the one she has with Lena Luthor, although lets just hope that she doesn't turn sour like her brother.
Supergirl will be returning to our screens very soon with friends and family in tow to fight aliens and to put the bad guys away. Now, she will have more help on her side, thanks to developments like Winn taking a leadership role at the D.E.O. She's going to need plenty of uplifting too, now that Mon-El has disappeared into a wormhole (though his disappearance will no doubt play a key role throughout Supergirl season 3).
Supergirl season 3 premieres Monday, October 9 at 8pm ET on The CW.
