I agree. Zayn's mum was also in the house when the whole scene kicked off. So if him and Gigi were already broken up at the time of the altercation, he flew his mum over to help him parent Khai anyway so its even more of a kick in the teeth if Yolanda came storming over to say how unfit he is to parent if she knows and Gigi knows, his mum is also there.Yeah, I do wonder how easy it is for her mum to manipulate her. The feeling I get from the quotes is that Zayn was fine to parent Khai when him and Gigi were happy, but when cracks started to show between them they decided he's no longer good enough.
Yolanda is all about that preachy clean, healthy lifestyle which is fine for her but I can imagine with Zayn's cannabis use, she probably thought it was her right to go take Khai bc she wasn't in fit hands. However, unlike both Yolanda's kids, Zayn has never had any problems with the law in terms of DUI's and getting caught with drugs on their person so I think its really rich of her to be taking a holier than thou stance on being the better carer when 2/3 of her kids have admitted to going/needing therapy. Bella was in rehab for the better half of 2020 and Anwar is so open about his lifestyle! It seems Gigi is the only kid who Yolanda still has some control over, especially since they moved closer to her on the farm.
