Simon.

Went in hard with his whole glitzy OTT 'look at me' Showbiz!! BS.

But his whole high-energy showbiz act failed (he couldn't keep up the pretence), and so now he is effectively sulking quietly in the shadows waiting to go home.

From the show's perspective - what a waste of everyone's time he's turned out to be.

He's probably an ok guy on some level but his BB experience has been nothing but a failed ego trip.
