It’s a number of things. The prime one being she was allegedly coerced into shagging him on 3 separate occasions, when he was 41 and she was 17/18.
She alleges there was an orgy with another 8 young girls and him and her, and she says some of the girls didn’t speak English but looked younger than she was.
Epstein gave him what he wanted - sex with young women / girls, hence the reason he risked hooking up with him again after Epstein had done time.
The fact he’s a Royal should make this a story that results in him being finished, but it won’t.
