In the Medical Wing, the nurses had to rip EVE's arm off so they could give her an injection in her empty arm socket.
WALL-E did not like this treatment of his girlfriend at all, so he left his room and took EVE's arm back.
Unfortunately, he accidentally used it to turn off the security system, so all the Looney Ward patients escaped and made WALL-E and EVE their king and Queen as they paraded them down the streets of the Axiom.
