Watergate, because BB7 was my first full series, I remember being astounded when Grace just threw water at Susie live on air, sparking a huge row with Aisleyne as she left.
It also sparked the big argument later in the night, Aisleyne and Richard vs Lisa and Imogen.
Susie demonstrated real class, while Grace demonstrated her utter lack of it. Then we had Lisa throwing the bike in a rage when Richard mocked her (almost killing Nikki!), she really did well in making her clique seize the moral high ground.
