I have read the Channel 4 webchats with Alex and Jonny.
Alex introduces himself by saying "Don't pee in the shower it's disgusting." The chat itself is Alex with the humour, both intentional and unintentional, removed. He says he can never be friends with Jonny because he pees in the shower. He has a go at Kate for flirting with him and nominating him. He says the housemates he has no desire ever to see again are Kate, Jonny and Alison (what a surprise -- NOT), because they were playing to the cameras. And he closes by reminding people not to pee in the shower, it's disgusting!
Jonny says that he and Alex are never going to be great buddies but he was glad he got to know him better in the last week. He says that housemates who accused him and Kate of playing to the cameras were just jealous because he and Kate were enjoying themselves and having fun. Asked if he is going to write in any papers or magazines, he said he is open to offers, but he will only tell what he sees as the truth. He will not slag anyone off, tell any lies or make up any stories about sex, and if that's all they want, he is not doing it. He said he would like his band to do better, but apart from that, he will go back to work as a firefighter. As far as he is concerned he is just Jonny, ordinary lad.
Obviously there are loads of other points both of them made and this is a crude summary, if you want to see the full interviews, go to the Channel 4 website.
