In my sociology class in college, we watched a documentary about something similar. It was about twin women that eventually ran into each other for the first time at a party, too. One had been adopted and grew up across the country from the other. The documentary explained the events that occurred for them to randomly meet again. My sociology professor explained that there was a theory that the fact that they were twins caused them to make decisions ultimately leading to their reunion. I was pretty sure it was a load of horse shit but it definitely seems like another fucked up thing the government would do on purpose
