Gareth did have that episode of envious and unbecoming snide remarks on twitter about Harness appearing on the Bru pod last year, but he is human and mostly fine. Barra seems a professional and decent guy at heart, trying to be understanding towards others. Marco and Max have displayed the most divisiveness with snide jabs at Bru over Swann, with Max spreading lies at times. Though, they do get it back from Matt Ellis.
I think part of the problem is that Marco and Max have never apologised for their own stirring of the pot, while blaming others.
