‘Lanterns’ Reveals Sinestro’s Dark Downfall and Its Impact on Hal Jordan
‘Lanterns‘ has been gradually unraveling the complexities of Hal Jordan and Sinestro’s tumultuous relationship, and the latest episodes have finally provided fans with the answers they have been eagerly awaiting. The HBO series has confirmed that Sinestro’s descent into villainy involved far more sinister elements than mere betrayal, directly affecting why Hal Jordan is no longer fully trusted by the Guardians of the Universe.
For dedicated Green Lantern enthusiasts, this revelation reshapes a long-standing piece of mythology that has been part of the comics for decades, while the show adds its unique twist to the narrative. The repercussions of this moment are already influencing the overall direction of the series, particularly regarding John Stewart’s intricate role within the Corps.
The show clarifies that Sinestro attempted a coup against the Guardians of the Universe, resulting in the death of one of them. This detail had been hinted at in earlier episodes, but ‘Lanterns’ finally laid it out clearly for viewers piecing together Hal and Sinestro’s shared past.
According to the show’s internal narrative, Sinestro’s coup led to the death of a Guardian, and Hal was the one who ultimately stopped him. Sheriff Kelly uncovers this information while researching the Lanterns online, providing the audience with a way into the lore without resorting to cumbersome flashbacks.

Interestingly, the only reason Sinestro was defeated was that Jordan turned against him and managed to stop his coup, although the show has been intentionally vague about the specifics of their final confrontation. Details regarding that encounter, including its duration, remain undisclosed, leaving ample room for the series to elaborate later.
This portrayal diverges from Sinestro’s original comic book backstory, where he uses his Green Lantern ring to seize control of his home planet, Korugar, concealing this from the Guardians until Hal Jordan reveals the truth. ‘Lanterns’ seems to be crafting a version of the character defined less by tyranny over his own world and more by a direct challenge to Oa’s leadership.
The Guardians themselves have not moved on from these events. Laura Linney’s Guardian informs John Stewart that the process for selecting new Green Lanterns was altered following Sinestro’s betrayal and the murder of a Guardian, highlighting how deeply this incident reshaped the Corps’ operations moving forward.
That mistrust extends to Hal Jordan. The Guardians no longer fully trust the Green Lantern legacy, and although Hal was the one who stopped Sinestro, the fact that the villain was once his mentor raises concerns that Hal might still be influenced by him.
This paranoia is a significant factor in John’s recruitment. Linney’s character tells John that Sinestro was essentially Hal’s father figure, and that Chandler’s hero still harbors feelings for his former mentor despite having taken him down. The Guardians appear to view John Stewart not just as a partner for Hal, but as a safeguard against the possibility of Hal’s loyalty wavering again.
Compounding this tension is the revelation that Hal remains in secret contact with Sinestro, who is keeping tabs on his former mentee’s life and even observing how he is training John. This unsettling twist suggests that the bond between Hal and Sinestro has not truly ended since the coup was thwarted.
The emotional ramifications of Sinestro’s actions are central to how ‘Lanterns’ develops John’s storyline. Linney’s Guardian explains to John that Sinestro was Hal Jordan’s mentor, and that their connection is something the Guardians found concerning, which clarifies why John was chosen despite Hal appearing to be the more seasoned Lantern.
The show also complicates the perception of Hal as a straightforward hero. John discovers that his own father was once offered a ring but was denied after admitting his fear, while John himself was raised to be fearless in hopes of gaining the Guardians’ approval. This backstory casts Hal’s fearless reputation in a new light, suggesting it may be tied to privilege rather than sheer bravery.
Fans have expressed mixed opinions on how the show is handling this revelation, with some praising the slow-burn approach to Sinestro and Hal’s dynamic, while others desire more concrete details about the coup itself. Regardless, the confirmation of a Guardian’s death at Sinestro’s hands has become one of the most discussed plot points of the season.
With Sinestro still alive and imprisoned, and Hal seemingly maintaining secret contact with him, the potential for this storyline to escalate remains wide open. Whether the show will reveal which specific Guardian was killed or keep that detail deliberately ambiguous is yet to be seen as the season progresses.
What do you think really transpired the night Sinestro turned against the Guardians, and do you believe Hal Jordan has genuinely moved on from his former mentor?
