I've had to go back and watch the e-bikes debacle again in pure disbelief that a) that's how she talks to him and b) that she chose to keep it in the vlog.
Her tone, the blinking eyes, the fury in her shaking head... all while he's quite calmly saying "I've got it wrong" and "yes I took us the wrong way" just seems horrible. This is the man you're going to marry in a few short days and you look so blindingly FURIOUS with him... and why? Because you had to cycle a bit further in the hot sun? Yes, that's mildly frustrating but not 'throw your ebike down, blinking back angry tears' levels of frustrating. I'm absolutely astounded that she thought it was a good idea to take that footage at all, let alone insert it into a vlog going out to 90k+ people.
