‘Lanterns’ Episode 4 Trailer Reveals Sinestro’s Sinister Plan and John Stewart’s Fate
HBO’s new DC drama ‘Lanterns‘ has taken its time in the first three episodes to build a slow-burning mystery set in a small Nebraska town, involving an alien murder and the uneasy alliance between two distinct Green Lanterns. What began as a grounded, noir-inspired cop drama has gradually expanded its scope, introducing cosmic stakes while maintaining its human essence.
Kyle Chandler’s seasoned Hal Jordan and Aaron Pierre’s novice John Stewart have been at the center of this tension since the pilot, with their contrasting personalities—one instinctive and free-spirited, the other cautious and methodical—shaping nearly every interaction. Meanwhile, Ulrich Thomsen’s Sinestro, Hal’s disgraced former mentor now imprisoned, has remained in the shadows, providing information while clearly scheming from behind bars.
The newly released trailer for the fourth episode, which dropped on Sunday, August 31, sharpens the focus on Sinestro’s agenda. In the clip, he questions Hal about Stewart, dismissing the rookie as merely “a contingency plan, a backup.” When Hal challenges him, Sinestro ominously warns that he might actually need to kill Stewart, reframing the entire season’s stakes.
This exchange comes just as the series appears poised to finally allow Stewart to don the ring he has trained for his entire life. Episode three revealed that Stewart’s parents, aware of the potential for Green Lantern eligibility to run in the family, raised him to be brave enough to qualify, and the new preview hints that this moment is finally within reach.
Fans reacting to the trailer have noted the growing divide between the two men, highlighting how Stewart’s discipline starkly contrasts with Hal’s increasingly erratic behavior influenced by Sinestro. This dynamic resonates with decades of Green Lantern Corps lore, where trust among ring-bearers is often fragile and fleeting.
The tension escalates further with Sinestro’s portrayal in the series. Once a member of the Corps, he was stripped of his ring for abusing his power, and has been manipulating events from his cell. The new preview positions him as the mastermind orchestrating Hal’s actions from behind bars.
The next episode is set to air on Sunday, September 6, continuing the show’s consistent weekly rollout since its August premiere. The launch attracted an impressive 9.3 million viewers within its first three days, surpassing the openings of both ‘Peacemaker’ and ‘Creature Commandos’ in the same DC Universe on HBO Max.

With several episodes still to come, ‘Lanterns’ has ample opportunity to explore the implications of Sinestro’s threat. Whether the series will pit Hal and John against each other or if Sinestro is merely manipulating events for his own benefit remains the most pressing question as we head into next week.
