Marty slammed the car into reverse, careening back to the road and heading towards Hill Valley. He flung the headpiece from his containment suit off his face impatiently, and the split second lapse in his concentration was followed by a frenzied braking after he spotted a figure in the road about fifty yards in front of him. He fought to keep his eyes open as he continued closer, but unfortunately he could neither stop nor swerve before he heard a sickening thunk as the figure collided with the front of the DeLorean and flew back onto the road.
He pushed the door up as fast as he could, tearing off his mask completely and running towards the figure, who looked like a woman at a closer glance. As he reached her side he felt a bit less guilty, it was clear that however hard he had hit her she had previous injuries that he couldn't have caused with the DeLorean. Her right shoulder had some sort of nasty gash that was covered in dried blood, and it looked like a small chunk of her side was missing and still bleeding sluggishly. The left side of her face was marred by a large purple bruise, and her lips were red with blood that dripped to her collar. The car crash was probably the least serious of her injuries, he thought, before wondering whether to move her or not. In the end, he decided to move her out of the road behind the large sign on the closest side, he could drive to Doc's pretty quickly.
As he was moving her, however, he caught a glimpse of the sign and almost dropped her. It was an advertisement for the new subdivision of Hill Valley, though he knew his parents had bought their house almost thirty years ago in the same neighborhood. After he dropped her behind it, he got back into the DeLorean and checked the time gauge, reading 1955. So it worked after all. He pulled the gull wing back down before turning the key to start the car, and his heart stopped when it didn't.
"No, no, c'mon, I need you to start," he said quickly, before growing frustrated, "There's a half-dead woman, for crying out loud!" He growled at the steering wheel before stepping out of the car and tearing off his suit, pushing the DeLorean behind the sign as well for safe keeping and running to Doc's house.
