No way in hell would Fanny Rat have been a good partner for Angela S! For a start she has young children and (if the article is to be believed) he was displeased with Amanda not training enough hours. I imagine he also wouldn't have liked Angela refusing to do late nights because she had to go home to her kids. And secondly, Carlos said Blackpool week that the judges being harsh on her with the VW and AS had really gotten to her. She also looked really nervous and unconfident with the Latin dances, and they obviously weren't her strong suit. Yes, I think she was a hard worker and determined, but she also needed encouragement. I don't think she would have gotten enough of that from FR.
And I shudder to think how much of a disaster he would have been with Layton. A few years ago Gio would have been the pro whose choreography I would have been most excited to see with a male ringer. What a stroke of luck (well, for everyone except poor Richie) that never happened.
Angela and Carlos were a perfect pairing, along with several others last year - Ellie and Vito, Layton and Nikita, Annabel and Johannes. Even Zara and Graziano and Giada have stayed friends and she went week 6.
If they can't find someone like Michelle Visage who can handle his bullshit without being affected by it, they just need to bench him.
