Nothing in the game shows that a member of the Royce family works at B and R, and therefore could have seen the MC's file go through, and make the connection with Lynette.Might be why he was accepted and Josy was not.
I was thinking more of a meeting in the upcoming episodes between the MC and Jill's mom (for example). He introduces himself, she asks him about his family, and there she makes the connection to what happened to their friends (Lynette's family), and this is how the MC might meet that side of his family.
Or not. It is not certain that DPC has planned to deal with this in the story.
