phm time travel fix it fic, Rocky wakes up in the past. BUT. Rocky wakes up allll the way back before the Eridian ship's even finished being built, so he can fully fix all the problems possible. He teaches about and shields them from radiation, he talks about relativity but still insists on carrying extra feul anyway, yada yada yada.
Years later, ryland is born and grows up. the petrova line is discovered. suddenly, the moment Stratt walks into his classroom, Ryland time-travels/remembers the future as well.
He's fully prepared to go into space.
He goes through the motions.
But then there's a signal from space, and suddenly the Eridians are showing up in their orbit with taumeba like "hello earth, we are here to help save you, plus we want to meet Ryland Grace."
Grace gets to stay on earth! Everyone lives!!! Nobody dies!!!!
