I wanted Katie and Anton to win, but they won't. Since Jay almost certainly has this in the bag (and I believe that it's unfair that he's in the competition with so much experience), I gave my votes to the strongest couple out of the other two - which is Kellie and Kevin.
At the start of the series, I didn't take to them, but Kellie's impressive work ethic has won me over. Also, I am increasingly disgusted by the tone of some of Jay's supporters on here. At least one is committing libel against the judges and the Clifton family in their determination to smear the reputation of anyone they see as a risk to Jay's (still inevitable) victory.
