Could Arlene have refused to accept the pay cut the others all took so lost herself the job? I don't know if that's what happened, but am just thinking it a possibility, in which case she lost it for herself. As for her replacement the best person would've been, in my opinion, the choreographer who was used to train the dancers to do the group dance. They're paying her to do that so why not pay her to be the other judge too? She's clearly knows her stuff because the dance was great, she's there on the programme already and Arlene used to choreograph group dances before so it has been done - the being a choreographer and a judge - before. I'm sorry I can't remember her name, but she knows more about dance than Alysha does, although I don't think she made herself look an idiot with the comments she made.
