I was surprised to see Guy Gardner alive at the start of this issue. But as the story went on I began to catch on the twist: Hal Jordan’s hallucinating about his dead friend. And why? Because Hal killed Guy Gardner in a fit of rage in Year 2. The fact that he’s seeing his dead friend everywhere and is having conversations with him just shows Hal’s beating himself up way worse than the Guardian of the Universes’ punishment.
