Cotton, Dougie, Mark and Aussie Blonde

They give Cotton and Dougie a three day long secret task

They give the fauxmance couple a Celebrity Chest to do

It was the very first celebrity chest Emily has done ALL SERIES. If they were really favouriting her they'd give her special tasks every day (like they do for Cotton.)

I agree Cotton and Mark are being favoured to some degree.

No fault of his own, Dougie will be celebrating his birthday on the 30th. Which means he will bound to get more air-time that day.
