I heard his real name was John Titor and that he wanted to stop the founding of San Dimas High School which would happen after the great drought of Los Angeles in 1960.

Instead he sabotaged William Mulholland's dam, in San Francisco, 60 years later leading to the great floods of the Water Wars altering the terrain and leading to it being a fixed point in time and not the terrible Russian-German nightmare that he escaped from.

All of this because he had read that water wings were the cause of the rise of the Soviets post-World War 2 while in his high school and blamed the inventor of them (At the time) for it all happening.

So I heard from some kid talking to a girl at 31 Flavors before I passed out.
