In the next episode of Supergirl, Kara (Melissa Benoist) and Alex (Chyler Leigh) travel back to Midvale to help Alex deal with what happened between her and Maggie (Floriana Lima). Besides getting to see an appearance by Helen Slater as Eliza Danvers, we are also supposed to see Erica Durance again as Alura Zor-El. This may be part of the past or it may tie into the upcoming story that includes Mon-El (Chris Wood).
In the clip below we see young Kara (Izabela Vidovic) and young Alex (Olivia Nikkanen) out in the woods trying to figure out what happened to a missing boy. According to his mother, he had been out in the woods with a telescope and a laptop taking images of the moon. Alex suggests that Kara may be able to find the laptop even in the dark, and we get the impression that Kara is often discouraged from using her powers… so the encouragement is odd.
She finds the laptop and wants to take it to the police, but Alex says they need more evidence since Kara was the last one scene with Kenny, the missing boy. We see the characters' personalities already at this younger age — Alex is the skeptic while Kara is hopeful and trusting.
Supergirl airs tonight at 8 p.m. ET on the CW.
