Sharon, in my opinion, made the right decision whilst coming across two faced. Over the past two episodes, 2 To Go have given two good performances whilst Verty had a Week-One 'mare. Would you want to go to a Verity concert with her murdering Whitney? I would rather stick a fork in my eyeball.
Note to VWS: Peter's diplomatic answer on The XTra Factor is how you cope with winning the live showdown. 'She will get something. She has come too far to get nothing.' No thanking the judges for making the fair decision.
