Supergirl Season 2 Episode 13: Mr. & Mrs. Mxyzptlk Sneak Preview

Following tonight's episode, which involved Supergirl dealing with Lillian Luthor and Metallo after that broke out of prison, The CW released a sneak preview for next Monday's "Mr. & Mrs. Mxyzptlk" episode. As you can tell by the title, it features the Woman of Steel encountering Mr. Mxyzptlk, the powerful fifth-dimensional trickster, for the first time.

In the preview itself, Mr. Mxyzptlk magically puts Kara into a wedding dress, drops to one knee, and proposes marriage to her. Obviously, she wants nothing to do with him, but he persists — even going so far as putting on a Superman-like costume. Fun!

When Mr. Mxyzptlk (guest star Peter Gadiot), a magical imp, shows up on Earth and declares his love for Kara (Melissa Benoist), she tries to let him down easy, thinking him harmless. However, he decides it's a challenge and starts to wreak havoc on National City. Mon-El (Chris Wood) has seen beings like Mr. Mxyzptlk on Daxam and knows how dangerous they can be. He and Kara argue over how to get rid of Mr. Mxyzptlk, further straining their relationship.

Meanwhile, Alex (Chyler Leigh) and Maggie (Floriana Lima) celebrate their first Valentine's Day together.

Stefan Pleszczynski directed the episode written by Jessica Queller & Sterling Gates.
