This week's "Supergirl" episode proved to be getting more intense as Kara Zor-El and Lena Luthor's friendship is put to the test. However, it seems like Kara's relationship with Mon-El will also be put to the test in "Supergirl" Season 2, Episode 13.

A sneak peek for "Mr. & Mrs. Mxyzptlk" was released just after "Luthors" and it shows Mr. Mxyzptlk, a well-known "Superman" supervillain/antihero and magical imp from the comic books, saying "I love you" and proposing to Kara as he magically puts her in a wedding dress. The video clip also shows Mon-El left only clad in boxers and white tank top at the DEO and the impish character wrecking havoc all over National City, even wearing a Superman outfit while at it.

According to ComicBook, the official plot synopsis of the upcoming episode indicates that Mon-El knows how dangerous beings like Mr. Mxyzptlk are as he encountered one before in Daxam. However, as any loveteam goes - let alone, a superhero and a one-of-her-kind loveteam - they will argue about it, which will further strain their already complicated relationship. That being said, have you ever wondered what Mon-El has to say about this new threat in his relationship with Kara?

In another post on the same publication, Chris Wood, who plays Mon-El in "Supergirl," dishes out in a recent TVLine interview that his character hates Mr. Mxyzptlk. He also stated that Mon-El also hates the fact that he somehow ruined the chance of him getting together with Kara and even more so, the clear manipulation of Mr. Mxyzptlk to marry Kara like she doesn't have a choice. Adding to Chris' heartwarming revelation on how his character truly feels about Kara is the upcoming fight scenes with Mr. Mxyzptlk, which will show Mon-El acting on what he truly wants to convey: "Don't touch her! She's mine."
