'Lanterns' Season Finale Reveals Who Killed Hal Jordan, Teases John Stewart's Future in DCU

The first season of 'Lanterns' has finally answered its biggest mystery, revealing who killed Hal Jordan while setting John Stewart on a very different path as the DCU's newest Green Lantern.

The HBO Max series, starring Kyle Chandler as veteran Green Lantern Hal Jordan and Aaron Pierre as John Stewart, concluded its first season with the episode 'Dirt and Stars'. The finale resolves the murder mystery introduced in the opening episode while positioning Stewart for his next major DCU appearance.

Who Killed Hal Jordan?

After spending much of the season investigating Hal's death, John finally discovers the truth, and the answer is far more personal than the larger Manhunter conspiracy initially suggested. Hal's killer is Sheriff Kerry Kane, played by Kelly Macdonald.

The finale reveals that Kerry knew her son Noah was a Manhunter and was determined to protect him. After Hal discovered Noah's secret and realised the potential danger he posed, he confronted Kerry and urged her to leave with her son.

Instead, Kerry chose Noah. She ultimately shot Hal in the head, killing the Green Lantern whose death had driven John's investigation throughout the season. The revelation ties the murder directly to one of the show's central themes: the lengths a parent will go to protect their child.

'Lanterns' co-creator Chris Mundy said the creative team had deliberately made Kerry the answer once Noah's Manhunter identity was established, because simply making Noah responsible for Hal's death would have been too straightforward.

The finale also confirms that Noah is a Manhunter, adding another layer to the show's exploration of programming, family and whether people are defined by their origins or by the choices they make. Noah had secretly worked with Sinestro and sought his own lantern, further connecting the Earth-bound mystery to the wider Green Lantern mythology.

John Stewart Becomes Earth's Green Lantern

While Hal's murder is finally solved, the finale is ultimately about John Stewart finding his own identity. After completing his investigation, John reclaims Hal's Green Lantern ring and embraces his role as Earth's Green Lantern, but on his own terms.

Rather than simply accepting the traditions and authority of the Guardians and the Green Lantern Corps, however, John chooses to define the role on his own terms. He even creates his own version of the traditional Green Lantern oath.

That decision is significant for the DCU's future. John tells Guy Gardner that he wants Earth for himself, effectively choosing to operate independently rather than simply becoming another Corps member following orders. His declaration, 'You take the stars, I'll take the dirt,' reinforces the grounded approach the series has taken with the character.

The finale also leaves John with access to the fear-infused lantern Sinestro forged for Noah. John uses it to recharge Hal's ring, creating an unconventional new chapter for his Green Lantern identity. Mundy has suggested that its unusual origins could have consequences for John in the future, describing the situation as full of possibilities.

John Stewart's DCU Future

John's journey will continue beyond 'Lanterns'. Although HBO Max has not yet officially announced a second season, Aaron Pierre's Stewart is confirmed to appear in James Gunn's upcoming DCU movie 'Man of Tomorrow', the sequel to 'Superman'. Pierre's return as John Stewart in the film would give the 'Lanterns' finale a direct connection to the wider franchise.

The 'Lanterns' finale therefore serves as both an ending and a beginning. Hal Jordan's story reaches a tragic conclusion, while John finally accepts the role he had spent much of his life resisting. With Sinestro's influence, Noah's unresolved future and John now operating as Earth's Green Lantern, the finale leaves plenty of material for the DCU to explore next.
