As much as I loved Pixie last year, it definitely was not a scam that she ended up in the bottom-two - enough people didn't vote for her to stay (me not included in that, given I gave her all six of my free votes that week out of fear

), and both Darcey and Len preferred Simon's dance that week. That's all there is to it.
However, what irritates me is when people talk about how much better Simon's dance was than Pixie's in the DO, because it wasn't. From what I remember on here at the time, not one person mentioned the fact that Simon actually went wrong after coming down the smaller set of stairs at the beginning, not to mention that as Craig pointed out, he didn't really use his upper body (mainly the arms) very well. Pixie's technique, while not perfect, was a lot better overall the second time round, and she used her upper body far more than Simon did. Yes, his dance was technically the better of the two, but near flawless? Not on your nelly.
Oh, and the three so-called 'illegal lifts' that were there the first time? Two of them were non-existent in the DO, but that was also never talked about much at the time.
