SPOILER WARNING: This article contains major spoilers for "Bunker Hill," the latest episode of Supergirl.
It's official: Nia Nal is a superhero. In "Bunker Hill," the latest episode of Supergirl, the cub reporter confessed to Kara that her dreams are premonitions of the near future. She then used those powers to prevent Manchester Black from killing Agent Liberty.
After Nia had an episode at work, Kara offhandedly mentioned it when she met with Alex and Brainiac-5 at the DEO. Brainy reacted viscerally to this news; however, when Kara and Alex asked about it, he refused to tell them. He explained his knowledge of the future could hurt the timeline and that all he could say was Nia is important.
Knowing this, Kara confronted Nia about her "epilepsy." Nia admitted that not only did she have premonitions, but that she is an alien herself. She and her family are from a planet called Naltor. Occasionally, this power manifests in the women of her family.
Now that she has this power herself, Nia considered it more of a curse, because she believed she was unable to prevent the terrible things she saw from coming to pass. Brainy quickly explained that wasn't true; what she saw was possible futures, which she could impact now that she had knowledge of them. He then helped her hone her ability and see her premonitions more clearly.
Because of her new grasp on her powers, Nia accompanied Kara and Brainy on their mission to meet Agent Liberty. Unfortunately, because Nia doesn't know Kara's secret identity, she got herself kidnapped alongside them. During their abduction, she put her powers to good use; a quick premonition showed her when to duck, so that her assailant would shoot her handcuffs instead of her. This action freed her and her friends.
Later, Nia pulled a similar move. As Supergirl struggled to free herself from some spilled Nth metal, Manchester Black attempted to shoot Agent Liberty. Nia, who had already seen this possible future, knew what to do next. She released an industrial hook from its mooring; it swung across the warehouse and knocked Black out cold, saving Agent Liberty from certain death.
Of course, Brainy -- who hails from the 31st century -- is likely familiar with Nia's ancestor: Nura Nal, the fan-favorite DC character better known as Dream Girl from the Legion of Super-Heroes. She was briefly known as Dreamer in the 1990s. Introduced in 1964 in Adventure Comics #317, Dream Girl comes from the planet Naltor, where most of the inhabitants possess precognitive abilities, in which they experience visions of the future through dreams.
Airing Sundays at 8 pm 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.
