Alex, Jade and Tim are perhaps treating Kate as she deserves to be treated and as she treated them, behind their backs, in the House.
Having left the House our 3 heroes have read the press reports and perhaps seen a few clips of Kate's fake personality, continuous theatrics, manipulation and firting with the lads(Spencer, Tim, Alex, PJ) for the benefits of the camera,the constant bullying of Jade, the humiliation of Jade, back biting and bitching, plotting with Jonny against innocent housemates, ungratefulness ( she could not even be bothered to thank her public vote), the fake emotions and tears whenever an advantage was to be had etc etc etc
Can you honestly blame the 3 of them for reacting that way ?
This in itself does not bother our precious princess. What does bother Kate is that without the help of 'that lot' her little show will flop. Jonny and Alison simply cannot pull in the viewing punters.
