Simon and Louis are always sniping at each other and always trying to out-do each other and I think that when it comes down to either one of their acts in the bottom two and the other one has to pick who goes, I do think they sometimes do vote out each others acts to get one over on each other and it's pathetic really because it isn't about the judges, it's about the contestants and they should pick who they like more and not for the reasons of getting back at the other judge
