"Harry was the one who should have set the the tone and simply said "we understand how you guys bond during the process and it sucks anyone has to go home but that is the way the game is played""
But that is so coddling isn't it? Harry's not his parent, he's paid to provide constructive criticism. Not pat him on the back for behaving like a child now that someone he likes is going home. If Q were to behave like that in a meeting with a record producer he would be done. His label isn't gonna say - oh he's only 21, its ok, he's actually a pretty mature 21. They are gonna say shut up and do what you are told or you are dropped. He's an adult trying to make it in an adult profession and thinking that he's entitled to being treated with kid gloves is ultimately not going to help him in that career. The Ariana Grande's and others of the world who do succeed do so because they are able to check their attitude and be a professional.
