he really is one massive mess

Me too....he is trying to be loved by everyone....it's so false.
He would never have shared the money...hopefully they have all seen through him.

I have days where I like him but then he does something that looks so fake and so insincere that I Uturn again completely.
I understand his panic when he realised he had pressed the button but not been fast enough...he was trying to avoid the vitreol he saw Jason receive from the entire house except Andy...he panicked. But no way was it true and he made himself look even more untrustworthy for that then he did for actually pressing the button.
