If there ever was a spark between the two guys in the game, it was long dead by the time you actually get there. Bill was such a tremendous asshole that his buddy couldn't put up with his shit for another day, so he took off, got bit by infected, and hanged himself, but not before leaving a note telling Bill how much he hated him.

It was absolutely not the lovey-dovey romance the HBO shitshow turned it into (and devoted an entire episode to). But this is current year and we're not allowed to show gays in a negative or even nuanced light, and they have to be shoved down your face.
