I wonder if Paul and Noel get on? To me, they seem like they both have issues with having a big ego and to be in control
I think the only difference is that Noel has had the life experience to be nicer to people and has a high respect for women. I heard Paul lives in a filthy mess and Liam and Noel have had to pay for him most of their lives. Maybe he thinks he's entitled to do whatever he wants with no consequences because he can use the excuse that he's the eldest?
If we want to believe Paul, Noel cut contact with him in the past and wasn't answering any text. There's an interview where Paul said that. So I don't think they have been on good terms for a long time.
Paul lived off them in the past. Noel got Paul a flat. Apparently, it was never in Paul's name and was later sold. Liam got him a new place in East Finchley. It's the flat where he currently lives. I think he has moved on Liam's payroll. I doubt he can afford on his own an expensive lawyer. If you look at his solicitors' website, it does not look like a tiny firm.
