The first episode of Lanterns ended with a huge twist: Hal Jordan is dead. Discovered by John Stewart and Sheriff Kane in Rushville, we see Hal's frozen body sitting upright with a bullet in his head at the end of the episode.
This sets up a major mystery about who's behind the big death (you can read our list of suspects here). However, one viewer has noticed something in the show's trailer, which might have blown the case wide open.
