I too felt that something sexual may be between Fiske and Molina because Fiske seemed just too concerned in a protective lover sort of way. Of course we know Molina would have to be bi because he had a hot and heavy fling with Kate, but Fiske's "secret" has to be that he is gay and in the closet.
I love this show and enjoy the twists and turns that it takes (I love mysteries and trying to solve puzzles). The best part of the show for me is whenever Glenn Close is on. She is fabulous in this role - what a terrific actress. Watching her character manipulate people and handle every situation that is thrown at her with such cool detachment (even her own son) is chilling, but fascinating.
I don't really care where it is going, because I so enjoy the journey.
