”Listen up! The situation has changed! I'll explain later! For now-- Let's go get those butchers!” - Captain America

The heroes gathered on Battleworld by the Beyonder have discovered someone spying on them at their camp. When the Torch corners her, the mystery woman introduces herself as Spider-Woman. When the other heroes question how another human they haven't previously met could be on Battleworld, Mister Fantastic theorizes that since the Beyonder constructed Battleworld from planetary fragments a portion of Earth must have been used as well.
