I agree Joseanne, and although Jayde says she is strong and could lift Karen, she might not be able to lift her in a proper "dancer's lift" as she is not fit. I noticed how Jayde struggled to get up at the end of the Flashdance and Shirley commented on it.
Speaking of Shirley, I read a number of comments online about how she is very much "for" the male dancers and "against" the women, and the sexist comments that she makes. If those comments were being made by Anton about the female dancers, it would obviously be unacceptable, and it's not acceptable in reverse. She definitely has favourites when she is supposed to be neutral, especially as she's head judge. There are calls online for her to be replaced.
