SPOILER WARNING: This article contains major spoilers for "Both Sides Now," the latest episode of Supergirl.
According to Mon-El, there's more to his marriage with Saturn Girl than meets the eye. In "Both Sides Now," the latest episode of Supergirl, he revealed to Martian Manhunter that he married Imra out of a sense of obligation.
Speaking to J'onn, Mon-El explained that he and Imra had been partners since the early days of the Legion of Super-Heroes. Her people were hostile towards those who survived Earth's extinction event, so they hatched a plan together. Since she was of a noble house on Titan, they decided to marry in order to forge an alliance between the two peoples.
The marriage started out as more of a partnership, since he was still mourning the loss of Supergirl. However, over time, they came to love one another. Towards the episode, Imra recalled the look he had on his face the first time he told her he loved her. Unfortunately, she only brought up the story to point out that it was the same way he looked at Supergirl since he returned. When Imra asked if he still loved Supergirl, he could only answer, "I don't know."
After Mon-El was upfront to Imra about his struggle, she had a confession of her own: she and Brainiac-5 had a secret mission they hadn't shared with him. She didn't get a chance to elaborate on that before the episode ended, so fans will have to wait until the show returns later this year to find out what exactly that mission is.
With this reveal about Mon-El's marriage, the show may be opening the door for Mon-El and Supergirl to reignite their relationship. After all, Mon-El described himself as "content" in his marriage, not "in love."
Returning later this year on The CW, Supergirl stars Melissa Benoist as the Girl of Steel, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers and Jeremy Jordan as Winn Schott, with appearances by Calista Flockhart as Cat Grant and Tyler Hoechlin as Superman.
