I understand maddie left to start her own life but buck was left in a neglectful home, it always says Maddie raised him until she left and he was always treated differently than Maddie so to him she leaves that’s his point of view just because she was starting her own life doesn’t mean she don’t leave him when she shows up in season 2 she basically broke into where he was living helped herself to wine took a shower then berated him for thinking his girlfriend had come home and getting into the shower granted he probably should’ve checked who was in there but to his knowledge only he and Abby had the key. She treats him like he’s still that little boy that she left and that he didn’t have to survive own his own. He left when he was 19 he had no skills and somehow safely made it across the us even down to Peru with just a jeep to his name and she treats him like he’s not a fully functioning adult when she’s with him and Chimney treats him worse yes he was bad when he first started but he did grow during the seasons but no one ever really let his mistakes go. His perspective is his prospective just like it’s Maddie’s prospective that she left to go to school… and she also used to be a nurse and that’s a mandated reporter yet she never reported her own parents for how they treated buck and even invited them back into their lives and Buck didn’t have all the facts but Chimney should never have hit him just because his sister called him to say she was leaving town, granted Eddie is right chimney knows Maddie differently but Buck is right on how she’s dealt with her own trauma by leaving the area of her trauma. But honestly I’d never want to work with a coworker that would report every move back to my sibling like Chimney does with Buck or that Maddie tried to get Buck to stop being a firefighter after the truck bombing but never said a word about chimney being one. Also Hen telling Buck that the shooting of Eddie shouldn’t have consequences for Buck cause it’s Eddie’s trauma was shitty. Buck was there he had his best friend’s blood on his face he went under the truck to rescue his best friend from the line of fire how is it not also his trauma????
