The first time period Nathaniel lands in is 105 years in the future, the Earth having been invaded and taken over by alien Lizard Folk after humanity was left vulnerable by World War III.
The second future he visits is during World War III, France under heavy occuptation and what remains of the inhabitants barely surviving.
Benevolent Alien Invasion: Younger generations in the Bad Future seem to think of their alien overlords as benevolent, though older generations think otherwise and keep it to themselves.
Break the Cutie: When Nathaniel runs into Rose in the second Bad Future, she had been reduced to a vagabond perfectly capable of (and willing to) kill a stranger to survive.
Cheese-Eating Surrender Monkeys: When Nathaniel asks the clerk if France resisted alien occupation, he admits that they (along with the rest of Europe) surrendered almost immediately, leading Europe being one of the last habitable places on Earth.
Riches to Rags: In the second Bad Future, Prince Ali (who scoffs when Nathaniel calls him prince) is surviving with Rose in a war-torn, military occupied Paris, with implications that he is forced to live in exile.
Stock Animal Diet: It comes as no surprise that Fluff loves carrots, though they're willing to eat anything fresh.
