I would pick them over any of the three they were saved over, kinda like Misha B last year or Cher Lloyd two years ago (yes, the sing-off was set up to push her to the final, but the sales figures show that it was the right decision )

I want to see the voting trends and patterns, like if Chris was picking up more and more votes, how tthe votes for the boybands varied, was Ella ever that popular and how quickly did her vote drop off..

Im guessing his lead got stronger as the series went along, and he picked up more sympathy votes (and support).
