"Cara pronounced Sara" doesn't get enough attention. And by attention, I mean mockery.
He was trying to humiliate her by going into these details about who he was with. This was the same guy who asked her to purchase condoms for him prior to the trip, so it’s all related.
By dishing out personal details like the pronunciation of her name, her possible occupation and her return to Bangkok, he was also trying to make his wife believe that she wasn’t a hooker. Him going there and purchasing sex wasn’t in line with his stated purpose of seeing if younger women could still be attracted to him. If he’s paying them, it completely negates that point.
I believe Dijana saw through all that, understood the game he was trying to play by painting a picture that he had a lot of options elsewhere, and she called out his bullshit. If his recent comedy routine is anything to go by, I’d say she has been vindicated. Lloyd seems to never get a woman past the initial date(s) and they do not want to pursue it further.
The best revenge is happiness. I think the contrasts between where those two are in their own personal lives right now couldn’t be more vivid.
