the easiest thing i can think of is maybe her parents know his? her background is a mystery to anyone who knows her in la (she comes from a wealthy british family with a lot of political power in the uk but she fled because they were trying to marry her off to some super lame guy she wasn’t about) but somehow, through some random connection, they met prior to her move? he’d be the only one who knows about her true roots. she would have sworn him to secrecy though.
