A few things that stood out to me in these last few videos:
1. Leo is making mean little digs at Karen a lot more. So much that it felt uncomfortable to me. I usually like the "Mummy and Me" videos bc of my own mom, but not these recent ones. Leo is MEAN and Karen is visibly hurt by it. She raised this beast, but like, damn.
2. Leo really thinks her parents' homes are hers. She was going on about "my lawns" when she was talking to Karen about the heat in the UK and all I could think was baby YOU don't have a lawn. You don't even have a condo. Go buy a property and decorate that!
3. Her sisters really don't f@#& with her, like at all. As Ja'mieKing noted, Leo never ever talks about them. Not until this last video. And it's more than just them not wanting to be on camera. If she was close to them, we would hear things like "Spending the weekend with my sister Charlotte, pack with me!" and she would show the places they visited, if not the people, and talk about all the fun things they do. But even disliking being on camera, a close sister would deign to appear like once a year at the holidays. Or at your extravagant 30th birthday party. They would support her in the whole “we’re a big happy family” theme Leo likes to push. But they don’t. Because they don’t like her.
The more she brings us into her wider family world, the more the (very deep) cracks are showing.
