I think people are reading two much in to the both Natalie and Gavin kissing Bruno thing.
For Natalie it actually added to the story of the dance, as in it was their to emphasise to "Jack" that she didnt want him, and he wasnt all that, and she wasnt going to fall for his charms again. So it fitted in well, and anyone that thought it was just to copy, i think are pushing it a bit.
Gavins one seemed to have no relevance to the dance story, but added to the cheekyness of the dance. However, i think for Gavin it was more about doing something with a shock factor, to make him look like he had a personality, now again for some people it will work, for others it will not.
And if your looking for a conspiracy, why did Gavin chose the judge that is known for making a big thing about SSCCOOTTTTT, rather than the one that keep on saying he is wooden (Craig). Now i dont see a conspiracy in it, im just showing that you can make anything seem a conspiracy either way!.
As for Scott being a bad loser, i thought he took all the comments he got last week (which i think went over the top), and was mature about it. God if i was him i would have gone over to Gavin after his score and said "...whose the weakest male dancer now!". As for Natalies look when she only got a nine, i think that was more of abut her wanting a 40 for Scott, for his hard work, after she felt bad about the week previous.
