i'll never get tired of explanations like this. Grayson's starting to become a very intriguing character with this new perspective despite having initially "met" him as a psycho in kmiyc. it reminds me even more that people and characters have different processing methods, some being borderline bizarre to others but still, different
and somehow chase kicking henry off the helicopter is forgotten hahahahaha i'm not saying it grayson is innocent but they're both fucked up in their own way and also grayson is spending his time apologizing to chase and there's also chase who chases away grayson because he's so irritated by grayson always hovering over him apologizing whenever he gets the chance,, so we can just understand both of them in their own way and we don't need to condone what they've done we just need to give grayson a chance because he's such a beautifully written character with many flaws hahahahaha
They didn’t even know that during that time Bliss the favorite child of the family called Greyson to come home and Greyson was like nope I can’t go to the East coast no one will look after his baby brother Chase. So Greyson called Larien instead to go to Bliss. It got Bliss pissed off because Greyson chose Chase. Everyone was busy with their life and yet only Greyson is worried about Chase, it maybe in an efff up way but he is indeed worried about him.

as what his parents say, grayson doesn't know/understand emotions which is why his actions we've seen so far in the related stories are all questionable. though we're not yet half-way through the part where grayson will start to learn what certain emotions really mean with the help of dane, and where the readers will realize that their parents really sucked at raising their children (but ash and koi are adorable), still, we'll see interesting sides and a small glimpse of grayson and dane's past, like their childhood, from this part (at least in the novel) and onwards. it might take a long while, but give grayson a chance just as how much you've given chase.
