there is very much an ingroup and outgroup situation going on in there at the moment; They have all felt a little bit powerless due to the fact that they have been trying to get rid of Aaron all along, and the public keep saving him this renders them as also rans in there eyes; the convo jay had about Aaron having it in the bag etc means they feel that Aaron has all the control, and as i said all the power; the same with the nominations he had the power again which lowers the groups self esteem
Take yesterday and today, the group have come together to try and make themselves feel better, more powerful and the way they have done this is by taking away some of that power from Aaron and bringing it back to the group; Theyre not talking to him, they are trying to bring him down, but they dont want it to seem negative about them (this is subconscious really) so they are again blaming the member of the outgroup which is Aaron saying look at us we all agree, so he must be wrong and everyone will see it like that (they did it after kissgate as well)
I hate pack mentality, and Tom is one of the worst for this, and its like once they get together they lose their individuality and become faceless group members and act accordingly (bit like a football crowd, or a group of rioters)
I know Aaron isnt blameless in this,but the fact he is getting the blame and not Louise just shows how important being a member of that ingroup is
(sorry psychology overload there)
