Lanterns mid-season trailer teases the return of Sinestro and the truth behind Hal Jordan's death

The new trailer jumps ten years after episode 5’s “Lights Out,” placing Aaron Pierre’s John Stewart back in the ruined town of Rushville and re‑uniting him with his former mentor, whose resentment over being supplanted is palpable. Nathan Fillion’s Guy Gardner appears for the first time, promising to explain how the former athletic director seized the Green Lantern ring after John declined it. Meanwhile, a Hal‑look‑alike walks beside John through a bleak wasteland, hinting at a possible “Hal‑ogram” that could keep Kyle Chandler’s performance alive despite the character’s hinted demise. The final cut also flashes a yellow‑tinged device and a silhouette of Ulrich Thomsen’s Thaal Sinestro, suggesting the series will explore the comic‑book origin of the Yellow Lantern Corps or at least weaponize fear as Sinestro famously does.

The trailer signals HBO Max’s strategy to deepen its DC slate by mining under‑utilized Green Lantern lore rather than relying on the franchise’s marquee heroes. By foregrounding Stewart, Gardner and Sinestro, the show aligns with the broader industry trend of expanding secondary characters into flagship roles—a move mirrored by Marvel’s “Ms. Marvel” and “Moon Knight.” This approach also dovetails with Warner Bros. Discovery’s push to interlink its streaming titles with upcoming DC films, potentially using the yellow‑ring storyline as a narrative bridge to the cinematic universe’s exploration of fear‑based villains.

If Hal Jordan truly exits, the series must recalibrate its emotional core, and Chandler’s departure could affect any planned cross‑media appearances. The introduction of Sinestro’s yellow ring raises the stakes for future episodes and may set up a direct tie‑in with the Yellow Lantern arc slated for the next DC film, but it also risks alienating viewers who tuned in for Jordan’s arc. The next episode airs Sunday on HBO Max and NOW TV; key moments to watch include the reveal of the yellow device, any concrete confirmation of Hal’s fate, and how Gardner’s backstory integrates with the broader Green Lantern mythos.
