Romeo gets Juliet's letter and they get married and move to the south of France to get away from their families and live happily ever after.
Gojira decides Hong Kong isn't worth it, either, and crosses the ocean and wipes out Los Angeles instead.
Arnold manages to kill Sarah Connor so John is never born, the human race is entirely wiped out, and the Earth becomes a peaceful planet where self-conscious intelligent machines live in perfect peace and harmony.
Buffy gets a letter from the school with her book list before arriving at school her first day. As a result, she buys her books beforehand and so never has to go to the library. She never meets Giles, she joins Cordelia's clique of airhead pretty girls, and the entire series is about the anxieties of trying to decide which blouse to wear or what color to paint her toenails, as the occasional student goes missing, eaten by the vampires, who without having to face a Slayer, realize that keeping a low profile is their best choice.
