Think Austin is dancing a ballroom, plus his support, so safe. Tom will make a creditable job of the Salsa, so safe. Thus, if John survives the drop zone, it will be two girlies in the dance-off.
I think Rachel is in danger again this week. Few achieve high marks with the Rumba. It's low impact and doesn't generally excite people into getting up and jigging about. I can't see her being awarded more than 32, which would probably leave her mid-table.
As for the others, Cherie dancing a Latin could be tricky.
I guess if either of these two are dancing first, it could hamper their chances further.
I had expected John to go this week, but I do think he is now on borrowed time. If not this week then possibly next. People are beginning to question his continuing presence in Strictly, and as much better dancers leave at his expense, this will simply grow and the number of people voting for him will diminish.
