Yeah, I think that Sugar clip tells us F3 won't be Sugar/Kenny/Crystal.
I disagree, the actual show is making us believe that the strongest alliance is Kenny/Crystal/Susie with Sugar and Matty as a 2some. We have show in the past that Sugar doesn't trust kenny and crystal. There has been no evidence to us that Sugar ever had a F3 alliance with Kenny and Crystal. The kenny/Sugar/Crystal F3 will be a surprise to the viewers if they are the F3.
