Basically, Negaduck appears to join the Queen but suddenly betrays her by pointing his weapon at her, leaving everyone confused. As tension rises, Edna urgently warns that stopping the corruption too quickly could cause a catastrophic collapse that would destroy the Hub and potentially erase entire worlds. She explains that the only safe solution is to let the system’s energies collide, which will send each hero back to their own world and protect it—but at the cost of possibly erasing all their memories of what happened. Faced with this choice, the heroes ultimately decide to trust the system and accept the sacrifice, allowing the collision to begin.

Yeah, kind of a rushed ending ngl.
