There was a lot of tension there. And Andrew isn't a prolific chatterbox himself. Lack of and or bad conversation is why Wayne split to start Mission. If you had an issue, Andy would just as soon as tell you to go fuck yourself as any thing else. Patricia was still with Andy for the spite fueled sisterhood era. To deny Wayne naming rights. Also why Patricia left and got with captain sensible(Dave) iIRC.

Wayne on the other hand seems about as level headed and nice a guy you'll find. Though if I had to chose between mission and sisters, I would still trend sisters. They just have a raw less produced sound than mission has. Though mission is great too.
