Fun Speculations & hidden hints.
1) Probably not true, but fun to ponder.
James is the straight one and Audra is his wife.
2) Just something I picked up on: when Michael said he was bi, Wes said something like "but we're all supposed to be gay...we're all gay" Like an actor who didn't know he had the choice to "play it bi"
3) On the groupings: No TV produce in his right mind isn't going to hedge his bets and make sure he has the "drama" of a straight guy in the final 3. On the other hand, they have been watching the interactions 24-7 and have a good Idea of safe bets so all the straights don't get eliminated.
4) Give the boy some credit - no matter if Wes or Franklin are the straight ones, James has eliminated as many straights as possible in every round (except the last if Wes is straight)
