The nasty bullies at Bru will have driven him away by showing him calling others cancer.
In all seriousness, I didn’t have a huge problem with him and felt others were too harsh on him, but people are allowed a negative opinion of others. I don’t get why he couldn’t have just ignored anything he didn’t like. It’s not like anyone was piling on him in real life or sending him abusive messages, so far as I am aware.
