wouldnt put it past Tim to be faking the love interest back in Australia so that when he arrives back here it drums up interest in him ... first photos etc
he knows what creates a story ...
In that case he should have kept quiet about it being 'fake'. I think these things are as much about what the producers encourage through the diary room as well.
And with juries I've never been that big a fan of losers deciding the winner. I think they should get at most 50% of the vote at the end. The audience should get at least half because they have live feed available to them.
