The rehearsal dinner is odd for Older Jamie though not as much Owen since it seems he did stay in touch with them. Henry brought the kids to see him at his restaurant so he must have stayed in touch with them some, Jamie being at the wedding itself didn't bother me at all. My parents invited people I'd only met once in my life before. I also don't know that I'd call Jamie a servant, I mean she was an employee as she was the gardener but that's not a position I'd call servant, though I could see that argument for Owen as the cook. Maybe that's just a personal thing though. Also some people invite all out of town guests to the rehearsal dinner.
Question I'm still trying to figure out, did Dani and Jamie settle in the States or the UK? It just seemed odd that Dani would fly back to Bly and Jamie would be able to get a flight right after her, with neither of them changing clothes. It makes more sense if they settled in the UK and they just had to drive/take a cab there.
