Ziggy has only just entered the BB house.
Naturally, he will come over very nice & friendly, willing & kind'n'all-that
But as time goes by, he might air a particular opinion on a particular subject or housemate.
BB will be watching carefully & one wrong move will be shown in the high-lights show each night.
I wouldn't get too excited on those odd's at the moment.
However, I think Ziggy came over well so far, & if he does continue that way, he does have a very good chance of winning.
We shall see
