Lol, are you one of the ones that think that one kiss was meant to mean she was a lesbian?
It has nothing to do with thinking. It has been stated that Left Behind was even written with the idea of her being a lesbian.
Where exactly did you get that from? I've heard from the people that worked on the game that the kiss was only meant to imply how close their friendship was and not if they wanted to have sex with eachother.
