Walking Einstein
Checking his wristwatch, Doc decided to save Marty the trouble of taking out the trash when he returned with Einstein. His assistant had taken the lab's upkeep very seriously lately; what would it hurt to nix his last chore of the day and treat him to a birthday burger?
He looked toward the 7-Eleven, brow furrowing as he replaced the trash can lid.
Einstein trotted down the sidewalk next to Marty.
But Marty was behind the wheel of his family's Nova, driving at a crawl with the hazards on.
He stuck his head out when he saw Doc.
"I passed!"
