It took him this long to say something to Jade, now that Tim is leaving on Friday he will be stuck in the house with Jonny, Kate and Jade. Alone with those three over the next few days it could be likely that he will tell Jonny and Kate what he really thinks about them when the occassion calls for it.
People are saying (on this forum) that he had a go at Jade, why didn't he go to Jonny? Well if he had approached Jonny and Kate and started shouting at them about how he really felt, he would have come over like Jade did last night when she pounced on them without good reason.
There is a time and place for these types of revelations and turning on Jonny and Kate at that time would have been the wrong time. His arguement was with Jade at that time and when the occassion calls for it over the next few days he will probably raise an issue with Jonny and Kate if they piss him off or talk about him behind his back!
