Personally I thought that in previous weeks, Kelly could (and probably should) have gone but was saved by the public vote. However, I think that last week she out-performed Sean in the skate-off. Some people have mentioned that they think she was 'lifted into the next round by her partner'. Again, I've said this myself in other weeks but I saw a large improvement last time.
I love the fact that the judges decide the person to leave on a single performance. It's all very well saying "So and so is capable of so much more so I'm saving them" but that could happen week after week (I've seen it happen on other reality shows) and if they can't perform well when it matters then it's probably best that those who can, stay.
Unless she makes an enormous leap forward this Saturday, I think Kelly will probably be the one to go. She should definitely give up the comebacks though. She's hopeless at them, bless her!
(Incidentally, I've only seen her mention gold medals as a response once. And that was probably after Jason accused her of looking like a man or a bull mastiff or something!)
