I think you didn't understand Grayson's notion when he means 'what will Dane do?' that's what's called growth he is trying to see it from a different persons perspective who he thinks is correct. I like Grayson character development a lot he had such endeavours and ups and downs in his thorny path to actually feel those emotions and for the first time he tried to think voluntarily also.
I feel you never tried to understand how Grayson brain works but please do try to get to know he is a much more complex and beautiful character inside <3

I feel like I'm in the minority since I really dislike Grayson lol
Bro's so spoiled and I really dislike that he doesn't take the fire station gig seriously. He's the one who used his father's influence to forcefully buy his way into the fire station, and now he wants to burn it down just because he's bored?? I really hope there's character development because that's too unlikeable haha
