After school Gaz, Mandy, Billy, and Dib went to Billy's house where Grim was trying to find something that could help the girls.
"I couldn't find anything. I'll just have to take your souls." Grim smirked.
"No way. Let me look." Dib said and ran downstairs.
"HEY! Only I go through the trunk!" Grim yelled, Dib didn't listen.
"What's this?" Dib asked and he held up a clock.
"That's a clock that can travel through time." Grim answered. Then Mandy's eyes widened.
"Grim, don't you know what this means?!" She asked.
"What?"
"It means that we can travel back in time before Dib and Zim accidentally blew up the school so we never got sewn together!" Gaz finished. Everyone was silent for a moment.
"But...I will never see you guys again!" Billy cried and hugged Dib, Gaz, and Mandy. They pushed him off.
"I think that's a good thing. I don't want to be attached to her...and I want to go home." Gaz replied. Mandy and Dib nodded in agreement.
"Well, they've made their decision. It's time to go back in time." Grim said, and turned the long hand on the clock backwards.
