The fact that they had to leave their oldest behind because they “couldn’t renew her passport” (why?? 🤔)
Someone on the other thread about this speculated that Clive is not the father of the 8yo. I wouldn't know, I haven't followed the story, but if she does have a different father, possibly he has some sense, and is keeping tight hold of his daughter's passport and refusing permission for her to be taken out of the country.
