Oh how much time do we have?
Vile in the way they talk about other people behind their backs, vile in the way they show a supreme lack of empathy with other howsmates, vile in their attitude to team work, vile in the nasty streak that is all over spencers face, vile for laughing and clapping when they refused to join in a task and lost one house member a (much longed for) letter, vile for being so smug, vile for expecting to be the centre of attention all the time. Vile in the way they achieve that.
If they acted as they have in real life they probably wouldn't have many good friends so I suspect it is all an act that they have learnt will get them tv air time and therefore MONEY.
Anyway what is scripted reality tv? Do they have a script and only get it at the last minute or are they just given key words and phrases to slip into the conversation?
