Intervention

May 30: With the help of Green Beetle, Black Beetle is able to defeat Mongul and imprison him again. They discover that the War World key has been stolen, while in Bludhaven, the Team return to base and realize that they need to turn their attention to saving Blue Beetle.

June 13: Blue Beetle boosts the Reach's image by defeating Toyman in Metropolis. On his way home, he is ambushed by Batgirl and Impulse, who act as decoys while Zatanna and Rocket subdue him. Elsewhere, Miss Martian picks Lagoon Boy up from Atlantis, his leg having healed.

June 14: The four heroes take Jaime back to the underground cavern in Bialya where the runaways were stored, and Zatanna sets about casting a spell to free Jaime from the Reach's control. When Green Beetle intervenes, the other Team members who were lying in wait reveal themselves and engage him in combat while the spell is completed. Both Beetles are placed off-mode and Batgirl and Zatanna explain that the cavern runes had their origin in a human mystic ritual that was the cause of Jaime's Scarab being placed off-mode when it first arrived on Earth. They even bring up the histories of the previous Blue Beetles Dan Garrett and Ted Kord. While en route from Atlantis, Miss Martian breaks up with Lagoon Boy having decided that they aren't right for each other. After Nightwing gets word on the status with Blue Beetle and Green Beetle, Miss Martian and Lagoon Boy arrive where they learn about what happened. While Lagoon Boy leaves to go watch some television Miss Martian later learns that she has missed her chance with Conner as Nightwing tells her that he has gone on a date with Wendy Harris. Meanwhile in Bialya, Queen Bee reveals to Mammoth, Shimmer, and Devastation that the Light's plans for the Reach, the Justice League, and the Team are set to proceed on schedule.
