SPOILER WARNING: This article contains major spoilers for "Crime and Punishment," the latest episode of Supergirl.
Kara Danvers just made a difficult decision about her future as the Girl of Steel. In "Crime and Punishment," the latest episode of Supergirl, she ultimately chose to "lay low" and hang up her cape for a little while.
In the wake of Red Daughter's White House massacre, Kara continued to use her powers to help people. However, she quickly realized that Lex's plan to frame her for Red Daughter's slaughter worked more efficiently than she had hoped. After saving a man from a car crash, he called her a traitor and told her his daughter was crushed by her betrayal before limping off-camera.
This incident inspired Kara to return to the source. She took Lena to Styker's Island to look for clues in Lex's cell. However, this plan backfired almost immediately; Otis Graves was there to meet them. He quickly sparked a prison riot, which caused immediate chaos. Though she deftly handled the prisoners, Otis himself proved to be more of a challenge when he revealed the Metallo technology keeping him alive.
Outgunned, Kara quickly changed outfits. As Kara Danvers, CatCo reporter, she tricked Otis into believing that Supergirl had fled the scene. He left, but Kara quickly found herself in the company of another inmate: Steve Lomeli, a man who leaked Department of Defense secrets about drone warfare to the press.
Though Lomeli was less than impressed with Supergirl's method of fighting, he was a big fan of Kara as a reporter -- so much so that he agreed to an interview. As Lex's neighbor at Stryker's, he had borne witness to much of Lex's planning and activity. Though Lomeli refused to reveal any of this information to Supergirl, he was more than happy to share it with Kara in the hopes it would bring Lex to true justice.
Following this, Kara had a moment of clarity. Now that the public doubted Supergirl, she needed to rely more on what she can do as a CatCo reporter. As such, she told Lena and Alex that Supergirl would be lying low for the foreseeable future, so that she could redouble her efforts as a reporter.
In Supergirl's absence, a new superhero will rise. Per the promo for "American Dreamer," next week's episode, Nia Nal's Dreamer will step in the fill the void left behind by the Girl of Steel.
Airing Sundays at 8 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen and Chyler Leigh as Alex Danvers.
