In Jack Reacher 2, a major part of the plot involves Reacher being informed that a woman has filed a paternity suit against him with regards to a 15-year old daughter he was unaware of. The daughter, Sam, says that this was her idea, and that she encouraged her mother to do it in the hopes of getting money.
Near the very end, it turns out Reacher has never met her mother, and they don't even recognize each other.
This begs the question: why on earth did they file against Jack Reacher? What connection did he have to them?
As far as I can tell, there is no way they even would have known he existed: evidently he's never met them, so he should just be one of 7 billion anonymous people on the planet. So how did they hear of him and come to file a suit against him if they have zero connection to him? How they would have ever even heard his name?
Had Sam's mother known another person whose name was also Jack Reacher?
