"This Extraordinary Being," the last episode of HBO's Watchmen, took a trip down memory lane. After Angela Abar ingested a drug known as Nostalgia, she relived her grandfather's memories and learned about his life in great detail. As it turns out, Will Reeves was once Hooded Justice, a founding member of the superhero group Minutemen. This also revealed the origin of the group's photo, which famously appeared in Alan Moore and Dave Gibbons' graphic novel of the same name.

Following the episode's airing, HBO posted the photo as it appeared on the show on its social media accounts. In addition to Hooded Justice, the photo shows Silhouette, Mothman, Dollar Bill, Nite Owl, Captain Metropolis and the first Silk Spectre from left to right. The Comedian kneels in front.

The photo, which was taken in this episode as Will attempted to reveal a series of attacks by the Ku Klux Klan, appeared in a famous panel from the comics (below). This team paved the way for the Watchmen, which formed a generation later.

In "If You Don't Like My Story, Write Your Own," Laurie Blake revealed her parents were members of the Minutemen. Her father, the Comedian, sexually assaulted her mother Sally Jupiter, aka Silk Spectre. Laurie took up the Silk Spectre moniker when she joined the Watchmen, but it looks like she went by the Comedienne after her father for some time following the events after the graphic novel.
