Time travel. If asked, people probably would presume it involved big shows of lighting, air ripples, distortions of the whatever continuum and so on. And they would all be wrong. Ruby Rose knew that and how could she not? She just travelled 30 years in the past.
Soulmates. Nobody knows how or why, but everyone has someone special out there. They are destined to meet sooner or later and have their 'happily ever after'.
This is how it had always been, this is how it will always be. Because who would ever reject the best chance at happiness?
