You were transported to Hill Valley in 1955, looking very different to the 1985 counterpart of Hill Valley. Suddenly, a guy wearing a black t-shirt, riding on a skateboard, while holding clocks bumped into you as he collapsed on the ground, dropping all of his clocks.

He gets back up though and brushes himself off, looking at you. "Hello, sorry if I... bumped into you. That skateboard made me go really fast, didn't it?"
