Grayson using his alpha status to exuse being a sociopath fr.
It wasn't only Grayson, his twin sister and their oldest brother (as observer) were involved too. Their omega dad had lost his sense of taste and smell so they wanted to test it. They made a cake with detergent in it and fed it to their omega dad, if their other dad hadn't come in time something irreversible could have happened. So their alpha dad separated them and never let them meet their omega dad without him being present ever again
If I remember correctly someone here said Grayson tried to kill his omega dad and that's why his other dad had to separate them both??
