Who else thinks robbie williams was high on x factor?

Yes I said this to my sister after his performance when Dermot was talking to him, his pupils were dilated, his eyes were very alert looking and his pupils were dancing, his answers to Dermots questions were short and frank, maybe he took it for extra confidence boost as it was his first return to the stage in a long time, but he was the mentor and xfactor is a family show, so shame on him, I like Robbie don't get me wrong, but ironically Robbie who was as high as a kite actually sang LIVE! Alexandra who was obviously "normal" mimed her way through her performance and she sang live in every show last year lol
