The whole moving in thing was weird, she made out that something serious was happening at home, then said his mum felt a bit ill and thought she had covid, so he had to move out.... But the rules have always been if anyone that he lived with had any covid symptoms then he would have had to isolate too - so was moving out just a way to get around that and still be able to go out?
I can imagine Helen being the type of person to mock him for being 32 and still living with his parents just as a way to manipulate him into moving in with her.

I have an endless supply of chocolate and alcohol, I'll get you a TV so you can play COD in bed..."
