You won't get a chance. From what I'm aware, we come from around the same time, but Dirk says you're all participating in a game. Which means you won't be present on Earth when she takes over. You won't have the chance to save the human population from being eradicated by her reign. You won't have the chance to save me.
Let's say you do. That's going to be an alternate timeline regardless because you can't change what's already happened to me.
