Having re-viewed all the dances, it's Peter who should go. Janette, Oti, Karen and their partners were "busting a gut," in that jive, his performance was only marginally better than "Dad Dancing." It amused me that at the end, reminiscent of a professional boxer at the end of a fight where he's lost every round, he stood with both arms in the air, in an attempt influence the judges and in his case, milk the applause.
Janette impresses me with her flexibility, in the "pro dance" a few weeks back, the one with the pool table, with the high kick she got her right foot above her head, whereas some like Joanne who I think is an absolute doll, only managed to get hers just above waist height.
