It's just silly in general in my opinion. He and Liam don't get on. Who cares? Fair enough a band is better when united but in my opinion they have never really liked each other from the start and have seemed to manage. I realise tension builds and builds to a point where things can get bad but he's walked out with three dates left, and he will make a solo album, no doubt, which won't be as popular and will get people clamouring for a reunion.
