He has been a producer's fave all series but at this point it is highly unlikely that he will win.
I have a feeling we are building up to a Christopher v Pav v Mark eviction storyline.
Introducing the money is power twist will give one of those 3 (Mark, being producer's preferred choice) the chance to "double cross" the house and walk with £25k.
Pav could take it, but so could Mark or even Christopher to surprise them both and us.
If Pav takes the money you are left with a Christopher v Mark eviction storyline.
(friend/lover v friend/lover)
If Mark takes the money you are left with a Christopher v Pav eviction storyline.
(underdog v underdog type)
If Mark took the money I think he would have one of his strops and make it quite funny.
