As for his mother I’d imagine she’s gone through a lot of
tit with Marcus. Look at how quickly his mood changed last night from ‘not a farewell post!’ to ‘
duck it, bye!’, I’d imagine he has plenty of tantrums and can snap just like that. He’s entitled and expects the world to bend around him - yes this may be related to his autism - but he once went as far as knifing his mother when she tried to tell him no and told him off about letting the cat into the living room (or something along those lines), and tbh dealing with
tit like that year on year really does wear you down. I do think she’s a bit spineless in the sense she could tell him to get a grip and look for a job rather than slobbing around online or drinking but at the end of the day he’s a grown man, stronger than her with a fierce temper and has shown no issue with harming her, she probably lets him do as he pleases to protect herself.
