Her absence last night was worrying news. I have always liked Natalie and, frankly, cannot see what those who do not like her have to complain about. Each to their own, I suppose.
In my layman's view, she is the most likely winner by a fair margin, but if there are underlying health problems that do not clear up quickly, it may well become difficult for her, which is very sad. I, for one, do not believe that any of this is put on to gain public sympathy. She was well out in front on the judges' scores and has no need to resort to such tactics. Nor do I think she would anyway.
As for what John Barrowman apparently said (didn't see that episode myself), she has never been in a dance-off so somebody must be voting for her. Does he have access to the figures?
