Lanterns Episode 4 ended with a car crash as Hal intentionally drops out of a moving car while John Stewart is still inside. This time, there is no ring for John to protect himself from the effects of the crash. Hal destroys the car because John had just lied to him about Zoe being the Manhunter that Antaan is hunting.The promo for next week's episode reveals that Rushville is in bad shape, making it one of the darker entries in the HBO series. But many believe that "Lights Out", the fifth Lanterns episode, will be important for the series, as it will be the transitional point between the 2016 and 2026 storylines. It would also prove that the trailers showed only half of the story.The Lanterns trailers featured scenes only from the 2016 storyline:There are three trailers for the series, and scenes in those teasers exclusively feature Hal and John working together in Rushville. But the show's creative team already confirmed in an interview from May that the main storyline of the series is divided into two timelines, one set in 2016 and the other set in the present, i.e., 2026.The last scene of the first episode already confirmed what the storyline set in 2026 will be about. We learn that Hal Jordan is mysteriously dead, and we don't know who killed him yet. The scene set in 2026 also reveals that the Macon Ranch is completely destroyed. Since then, Lanterns has not returned to the 2026 storyline since the closing minutes of the first episode.However, as the DCU series is four episodes in, fans are going back to the trailers, and they are discovering that they exclusively feature scenes from the 2016 timeline. While it is understandable that the trailers did not spoil the death of Hal Jordan, they hardly featured scenes from 2026.Apart from a glimpse of Nathan Fillion's Guy Gardner or John Stewart with a beard, most of the scenes in the trailers featured Hal along with his mentee. Given that John is still clean-shaven in those scenes, we can ascertain that the production team managed to keep an entire storyline a secret.Episode 5 might be the last episode set in 2016: View this post on Instagram Instagram PostHBO officially released the promo for episode 5, which sees Rushville on high alert. Episode 4 already ended with John calling Antaan to inform him that they have the Manhunter's identity. At that time, it was unclear if John was going to reveal Zoe as the Manhunter or not. But considering that Hal is the one who is going to meet Antaan, the experienced Green Lantern has no qualms about giving away Zoe's identity.Thus, next week's episode could explain why the Macon Ranch is devastated in the episode 1 time jump. Moreover, "Lights Out" could also end with a time jump to the aftermath of Hal's body being found, setting up Lanterns Episodes 5, 6, 7, and 8, which would follow John trying to solve his mentor's murder.Therefore, for now, it seems that the first five episodes of the series would explain the central mystery at the heart of the show: Hal Jordan's inexplicable murder.
