I think the worst thing he's filmed, for me, has to be right at the very beginning of him getting involved in the vlogs. He took Isla swimming, she was really little, maybe around 4. I think she had a rubber ring on and wasn't old enough to have her face under the water.
He was in the baby pool filming her and put the camera underwater. He filmed her backside for a fair amount of time, her walking and trying to kick.
It was absolutely disgusting, as a parent myself I just can't get my head around why the hell you would film something like that.
Another was when he kissed Isabelle on the lips, had his hand over her shoulder touching her breast area (I'm pretty sure there are clips of this somewhere) and then hiding under her bed
The best thing to come from all those girls and young adults coming forward in 2018 was the fact the weird relationship he had with Isabelle changed. Something shifted there and although you still see little snippets of it, it is nothing like it used to be.
Urgh and when he collected her from that school trip in France, that was such a strange encounter!
