There are housemates that haven't lived up to my expectations - Ed & Jasmin most notably - but Tim is the only one about whom I've done a complete backflip. My first impression was "ugh god I hope he goes first", but he's really grown on me. He reminds me very much of my brother in that (IMO) he's very much a 'lovable torment'...yes he likes to stir the pot and niggle others, but I really don't think there's any malice in it.
