I'd say Judy is safe for the time being- Tim's elder statesman vote will now go to her. Scott must surely be slowly waining- him and Alison must share the "fun" vote, but I think, in a push between the two, Scott has more fans than Alison.
Thom and Mark are splitting the "hunk" vote and again I think Thom edges there- Simon will get the bounce Kimbot got in her series being in the bottom two early on. Sunetra I think has plenty of fans remaining, so I'd say Mark and Alison are the two most at risk (we saw that with Mark) but of course it depends who they're up against in the bottom two...
