Yuna's short program was beautiful and it was underscored and Adelina's with her easier combination and flying through her choreography was over scored having them just about in a dead heat. Adelina should have been in 3rd place and a very comfortable distant away for both Yuna and Carolina after the SP. While I will give you that after Yuna was done with that long program she looked so relieved to just have it over, her program was great. Not Vancouver great, but great. Yuna gave an interview in which she said that after the SP scoring she did not expect much in terms of her long program score, so maybe that is why she did not "have her heart on the ice". She already new that the judging was biased and not necessarily the pressure from her federation to compete.
As far as Adelina being better that night, she was not better than Yuna or Carolina and should have a bronze medal. I am trying so hard not talk bad about her program, but, it is hard because I hated it. I have tendency to re-watch programs on youtube sometimes years later, but I have no interest in watching that again. It was almost a circus like performance. Sure, Adelina delivered a spirited performance, but she was skating at home with the crowd screaming for her, so it is pretty easy to be spirited under those circumstances.
That being said, unless it could be proven that Adelina engaged in wrong doing her medal should not be taken away, but I don't have a problem with a solution like Salt Lake where two OGM ended up being awarded in the pairs event after questionable judging. Honestly, I don't think anything will be done because the ISU wants to pretend like there is not issue. However, if it were my job to take a medal from someone and it was determined that Adelina's or anyone else's should be taken away, I would be willing to go up to their face and do it. I would feel bad though and want to give them a hug.
