Work Text:
Doc finally understood the true meaning of exhaustion.
I think every cell in my body is ready to shut down.
He slumped back, looking at the lightning rod he had been working on as it lay on the table.
That’s progress… Maybe I have earned myself a rest…
But then, he glanced at the calendar.
Tomorrow was Saturday. No, it already was Saturday—it was 2AM.
He would have to keep going. Marty believed in him—believed that Doc could get him back home.
A new determination filled him as he resumed his work.
He would not let Marty down.
