I always find it interesting when a housemate goes in to big cheers, is a possible favourite, seems lovely etc, and by the time they leave it's all changed. What are some big examples of this you can think of?
A recent one is obviously Pauline. Big favourite on launch night, evicted to huge boos in the second week.
Others than come to mind:
Wolfy
Bea (I remember how lovely and likeable she seemed on launch night, it was quite freaky how she gradually became so malicious

)
Rebekah (I'm sure she was popular on launch night, but I think she started to ruin it as early as the first highlights show)
Toya
