"Who is this?"
"The real question is who are you? Everyone around you thinks you're just a mild-mannered reporter but I know the truth."
Kara Danvers and Rick Malverne
"Alex" is the nineteenth episode of the second season of Supergirl, and the thirty-ninth episode overall. It aired on May 1, 2017.


Alex is kidnapped and the kidnapper threatens to kill her unless Supergirl releases a notorious criminal from prison. Supergirl and Maggie have always had different approaches to apprehending criminals but this time they must work together to save Alex. Meanwhile, Rhea has an interesting proposal for Lena.[1]


  • When Kara is talking to J'onn, she says she can't " fast enough and turn back time...", which is a reference to a scene in the 1978 film Superman, where Superman uses his powers to travel back in time to save Lois Lane.
  • This is the first Supergirl episode to be named after a character in a civilian sense and the fifth episode overall in the Arrowverse to do so, after "Sara", "The Secret Origin of Felicity Smoak", "Who is Harrison Wells?" and "My Name Is Oliver Queen".
    • This is also the second episode Arrowverse to only contain the character's name, after "Sara".


  • In one scene, Malverne goes from having handcuffs on to checking his watch without the cuffs.
