The interview was rubbish..
Davina: Cairon aren't you just devastated?
Cairon: No not really.
Davina: But aren't you just gutted?
Cairon: No I'm just tired.
Davina: Oh I can see it on your face you are just devastated.
Cairon: No, I knew I was leaving.
Davina: It's so sad you're devastated.
Then at the end of the interview...
Davina: He is just so devastated to be out, IT'S CAIRON!
Then there was the 'Noirins leading Sree on' rubbish. Cairon stated that Noirin had been blunt with Sree but Davina and Feltz knew better.
Not suprised at all that he was defensive, they apparently know more about events in the house than him.
