Upon confronting the villains, Lagoon Boy is captured and shipped off to the Light's Partner while Nightwing and Artemis deal with the ground assault. They soon find themselves up against Aqualad, who fails to destroy the rocket but kills Artemis with his water sword. The rocket explodes anyway, and the heroes are unable to save their fallen friend. March 20: Aqualad reports to Black Manta, who reveals that he had planted the bomb that destroyed the rocket in order to test whether his son would take credit for the victory or not.

Artemis is given an amulet (which Zatanna had made without knowing its purpose) that will disguise her looks to everyone except Nightwing, Aqualad and Wally, then she and Aqualad leave together.

While in containment, Blue Beetle overhears his captors' intentions to remove his scarab at the cost of his life. Impulse eventually frees Blue Beetle revealing that in the future, a Blue Beetle has taken over the Earth and enslaved mankind. Miss Martian encounters Aqualad for the first time since Artemis' death and in a rage, telepathically attacks him leading her to discover the truth about Aqualad and Artemis as double agents.
