Say what you want about William but I’m happy he and Noora ended up together.
All the shit that happened in London makes sense once you try to see it from his POV; Pretty much his whole life things went wrong, be it his sister or his brother or his parents, there was always something he had to keep his guard up about.
So I can’t blame him for wanting to keep his dad in his life once he had him in it, after so much time having no-one (yes he had Noora but at the time he likely didn’t think he was good for her so he kept his distance)
A lot of this fandom see it as ‘oh he did a shitty thing, he shouldn’t be forgiven’ but there’s a difference between doing a shitty thing because you’re a shitty person, and doing a shitty thing to protect yourself and those you care about (again William probably thought he only caused trouble for Noora); so before you go bitching about him coming back, try to remember that emotional trauma can really mess with someone’s head for years after; and if you think he hasn’t had emotional trauma, did you even pay attention in season 1 and 2??
