Rachel has a pleasant personality and that's exactly why she won :)

She was an appalling housemate. Rex was a great housemate.:nono:

Rex was robbed. He carried that series. :bawling:

She was hardly appalling. Especially compared to Rex, who only used completely unwitty insults of "omg Rebecca is fat" "omg Rachel is boring" and "omg Sara is slutty" ad nauseam, was ridiculous misogynistic, and just in general a creepy, gross, sexist sociopath.
