I'd be VERY surprised if Sam made bottom2- even if he does I cant see him getting eliminated. Would be money down the drain to bet on him IMO.
Laura is possible for bottom2 but not sure if she would go - against Johnson she wont, against Chloe there is a chance (she performed better tonight but this would be her third time B2 and Chloes 1st so maybe they would be swayed against her because of that)
Very likely johnson will be out tonight- i had a tenner on 67/1 for him to win so would be very happy if not.
