SPOILER WARNING: This article contains major spoilers for "Back From the Future -- Part One," the latest episode of Supergirl.
It's official! The Hall of Justice officially received its moniker in "Back From the Future -- Part One," the latest episode of Supergirl.
The episode saw Winn Schott return from the 31st century to confront the Toyman, his evil doppelganger from another universe. During his reunion with Team Supergirl, he shared a few tidbits about the future, including his marriage to Lightning Lass. Then, when J'onn mentioned the new headquarters established for the Arrowverse's heroes in "Crisis on Infinite Earths," Winn revealed that it was called the Hall of Justice in his new time period.
"Well, in the wake of Crisis, Kara, Kal-El, Barry, Kate -- we established a headquarters from which to fight crime," J'onn began to explain.
"Oh! In the future, they call it a Hall of Justice," Winn interjected, drawing a gasp and an exclamation of approval from Kara.
"I thought that, since LuthorCorp now owns the DEO, National City could use its own collective," J'onn continued. "A headquarters to keep this city safe, to work outside of corporate and government oversight, whose interests might not always side with justice."
"So, like STAR Labs," Alex pointed out, to which Kara added, "Or the Arrow bunker."
"A place for my Super Friends to work, whenever they should need it," J'onn agreed. He called this new space the Tower.
The Tower isn't just a home base for Team Supergirl. J'onn took some of the Arrowverse's other heroes into consideration when building the space. He placed several call buttons on the wall, with direct lines to Supergirl, Batwoman, the Flash, Dreamer, Brainy and himself.
In "Crisis on Infinite Earths," the multiverse was condensed into one world: Earth-Prime. As part of this shift, the Flash renovated an old STAR Labs space and turned it into a headquarters for all of the Arrowverse's heroes, including Black Lightning and the Legends of Tomorrow. Though fans have been calling it the Hall of Justice, after its resemblance to the same building from the Super Friends cartoon, it did not receive this name officially -- until today.
Airing Sundays at 9 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter and Chyler Leigh as Alex Danvers.
