I think it is a combination of things:

1. They have finally realized that Freddie must be liked by the viewers and they might look bad by being mean to him.

2. They thought they wouldn't be up for eviction for a long time and now that they are, they are sh*tting themselves.

3. Freddie has dumbed himself down to be more on their level.

Was it just me or was anyone else loving when Freddie hit Sophie in the face and in the tits with the paint balloons? THAT is what you call Karma!! LOL

Look at this thread on Digitalspy

Noirin mentioning the "AWWW" last night on Live Feed

Anyone record Noirin saying to Marcus (around 4am) "oh you respect halfwit? yeah everyone does now just cos we heard ****ing AWWW cos people feel sorry for him"

Really? hahahaha how transparent do they look now!?
