Yeah, to be honest that's where I think Imogen comes in; she actually made an effort to get on with everyone.
But saying that, I think Richard doesn't come across as being caught up in the whole friendship thing - in the final week he's trying to get on with everyone.
The friendships I think are genuine are:
Pete and Nikki - it's more a romance then a friendship I suppose, but I still believe that even if they don't stay together, they're a great couple as friends and I hope they stay friends even if they did split up. They have a laugh together and try not to take stuff too seriously.
Glyn and Jennie - These two seem to be getting really close as more and more people are being evicted. They both come across to me as genuine people anyway, and I think they feel that they have more in common since they're both the same age and are youngest in the house so therefore are treated more or less the same way by the other HMs (read: Aisleyne

). And they have a laugh together and have even talked about meeting up after they leave the house and all that, so I think and hope they'll stay friends.
