The curse is actually the two acts either side of Mary; and seeing as she was on first last week, that didn't apply. Cher or Katie, technically, would be the victims of the Mary curse but I don't really believe it seeing as she's been a bit rubbish this week and last week
. Wouldn't be too shocked if Cher was in the bottom three in a shock result though - on first; week 5 curse and this so called Mary curse... on top of the fact she was average.
