Supergirl Season 2, Episode 13 Synopsis: “Mr. & Mrs. Mxyzptlk”


This week on Supergirl, Mr. Mxyzptlk arrives to court Kara. However, when she turns him down, he unleashes his mischievous powers.

Last week on Supergirl‘s “Luthors” episode, Lena Luthor was framed for breaking out Metallo and the subsequent escape of her mother. It was up to Kara to prove her friend’s innocence.

As Lillian Luthor went on trial for her crimes, Lena was ostracized on both fronts—for being a Luthor and for turning her own mother in to the authorities. When Metallo acquires Kryptonite and helps Lillian escape during court proceedings, all fingers point to Lena as the accomplice. Making matters worse, Lena is shown on video stealing the incriminating evidence.

Lena is arrested and charged with Metallo and Lillian’s escape. The perception of her guilt is further cemented when Metallo breaks Lena out of prison. Reuniting with her mother, Lena learns that Lillian needs her Luthor blood to open Lex’s secret vault containing a cache of anti-Superman weapons.

When Kara and the DEO finally locate Lena, they also learn that Metallo’s synthetic Kryptonite is highly unstable—with its accelerated decay rate, the resulting explosion would be devastating.

Kara flies to their location and engages in a deadly fight with Metallo. J’onn arrives just in time to help. And as Metallo’s Kryptonite went critical, Kara flew herself and Lena out of harm’s way. Because of the event and Kara’s unwavering faith, her friendship with Lena was now cemented.

In the realm of Kara’s personal life, she learned that Mon-El was truly in love with her. As the two finally admitted feelings for each other, a bright light zipped around them, eventually materializing into a mysterious visitor calling himself “Mr. Mxyzptlk”—a powerful god-like villain familiar to Superman fans.

This week, Mr. Mxyzptlk attempts to court Kara, who thinks he’s harmless until she rejects him. Even though Kara doesn’t need it, I’m sure Mon-El will step in to defend her honor and attempt to rid the imp himself. Here’s the official synopsis:

“Mr. Mxyzptlk”

"DC COMICS’ MR. MXYZPTLK HITS NATIONAL CITY – 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.
