Every night, she tells him the same thing, as regular as the tide: I know you’ll find me. You won’t let anything stand in your way. Not even the universe. I know what people tell you, what you sometimes tell yourself, that it’s impossible. But I know—I know—it’s not impossible. Her entire body vibrates with the force of her convictions. It’s not impossible because you’re doing it. You believe in the existence of a multiverse, but I believe in you.
