It was a Saturday afternoon and Mandy and Grim were on the couch. Billy didn't know what to do.
"Billy, how about you make me a sandwich." Mandy said.
"Okay Mandy!" Billy said and ran into the kitchen.
"Ya know he's just gonna mess it up." Grim said.
"I don't care. I'm hungry." Mandy replied.
Grim sighed. "I wish I could've got stuck with de old Billy and Mandy."
Billy ran back with a messy sandwich. "Old selves? You mean when we're old people?" Billy asked.
"No you nitwit!" Grim yelled.
"Our shadow people? Cause they're way annoying." Mandy asked.
"No. Let me show you." Grim said and opened a portal. The gang went back in time. It was the year 1998, and Billy and Mandy were outside. The old Mandy was tall and had long blonde pigtails, dot eyes, a nose, a long pink dress, and a band aid on her head. Billy looked exactly the same, but he had a larger hat and a smaller nose, and he was passed out on the ground with blood gushing out of his head.
"Am I DEAD?" Billy shrieked.
"Oh, hi there! You must be our future selves. And the Grim reaper? Wowie! I'm Mandy 1, and Billy 1 here fainted from blood loss." Mandy 1 said cheerfully, unlike the Mandy we know.
"Mandy 1..? Does that make us the second version?" Mandy 2 asked.
"Yes." Grim answered.
"Maybe these are our shadows. Our Billy is dumb, and shadow Billy was supposed to be smarter, but...he got hit in the head?" Mandy 2 asked.
"Trepanned, actually. I drilled a whole in our heads! I just need to bandage Billy's head." Mandy 1 chuckled. Mandy, Billy, and Grim winced. Mandy 1 put a bandage on Billy's head. "It'll take time for him to get back up again." Mandy 1 said.
