It's simpleAlthough my intuition says Franklin's the straightest, I know that can go wrong at times. It's only 50% accurate.
You know that the producers want one straight guy at the end, right? How can they ensure that if there are two left in the previous round? There is only one way and one way only - put the two straight guys together. Then, and only then, one and only one will be eliminated. Otherwise both could be eliminated. Franklin was paired with Sean - straight. Therefore Franklin is straight. End of story.
Franklin is wonderful. He's cute. I wouldn't be surprised if he switches or tries out gay sex after this. I really fell that he has gotten his feelings into the whole thing. But, there is no question, he is the straight guy. If he weren't, I'd pick him for sure, he's so cute.
