WATCH: Kara Sees Krypton and Her Mother in new "Supergirl" Clips

"Supergirl" is about to take Kara back to Krypton, but not in the way you'd expect. When Kara is incapacitated by an alien vessel, she begins to hallucinate what her life would like if Krypton never exploded. Her mother is still alive, her family is safe, even Kal-El is with her.

In these two clips previewing tonight's episode -- based on Alan Moore and Dave Gibbons' classic Superman story "For the Man Who Has Everything" -- Kara (Melissa Benoist) begins to question her reality. Back on Earth, Alex Danvers (Chyler Leigh) and Hank Henshaw (David Harewood) try to rescue Kara from the alien creature.
