Lanterns' penultimate episode, "The Jordan Boys Legacy," opens in 1975, where we meet a young, very stubborn Hal Jordan. After getting into trouble at school, he and his dad talk about the "Jordan boys legacy," and Martin gives his son a key to a safe in the event anything happens to him (just as his father did years earlier).
Hal, who has refused to let go of the ball from his baseball game at school, is urged by Martin to throw it away because it's "f***ing exhausting" to "hold onto it forever." This metaphor will matter later.
Back in 2026, John brings the Halogram up to speed about what happened, and both Ch'p and Mogo receive a mention. Eventually, the Halogram demands to see Sheriff Kerry, and a touching reunion follows, despite the 2006 version of Hal obviously having no memory of her.
John gets his hands on the $315,000 he needs to keep Maggie off his back, and after the Halogram posits that Kerry could be the killer, they head back to the storage locker and find only a backpack with a canteen, poncho, protein bars, and a gun. There's also one of those black portals that transports John and the Halogram to Antaan's decimated planet.
We learn that te Manhunter released a gas that made everyone terrified, leading them to jump from the city above to the ground below. There are bodies everywhere, but John and the Halogram find a boat that they use to head toward a mysterious light in the distance.
On the way, the gas—which is still in the atmosphere—affects John, who sees his father and younger self, and the apples that were shot off his head as a child. Before he can shoot himself, the Halogram intervenes and reveals how his dad really died. In a major departure from the comics, it's revealed that Martin killed himself (on the page, he was a test pilot who died in an accident while Hal watched on).
Martin's father also took his own life, and Martin left Hal a letter saying that "the same pain" was the "Jordan boys legacy," passed down from one son to the next. Hal isn't fearless because he's brave, it's because he's broken.
John wonders whether Hal might have also killed himself, but before they can discuss the theory that Kerry found him and removed the gun any further, a hooded figure grabs the Halogram and threatens to kill him unless they give him their boat. The Halogram vanishes, and John punches the mysterious figure to the ground: it's Sinestro.
In another flashback to 1975, we see the young Hal walk out to the field where he threw that baseball and pick it up, suggesting, like his dad, he can't throw away his baggage either.
And that's it. The penultimate episode has left the Lanterns finale with a lot of heavy lifting to do, including explaining how and why Sinestro is on that planet, whether the fear gas has any ties to the fear-based Sinestro Corps, who killed Hal, and how John becomes a Green Lantern by the time Man of Tomorrow begins.
Very little happened in this seventh chapter, and for those keeping count, there isn't a single Green Lantern construct. It's also unclear how Lanterns connects to Checkmate and Salvation, two elements from Peacemaker that James Gunn suggested would be key in this series.
Seven episodes of Lanterns are now streaming on HBO Max.
