At a glance you wouldn't suspect anything was different with Chase or Wilson. However, the problem came when House himself turned his attention to them, since a glance was all he needed to know what was on Wilson's mind and Chase was the type to wear his emotions on his sleeves.

He saw those little unnecessary touches that no one would think twice about as they walked passed each other. He would catch Wilson watching Chase through the glass, his eyes never leaving the other as the Australian chewed lightly on his pen while working on a crossword. There was once, but only once, when he'd been able to catch a glimpse at Chase's neck, the bite marks telling him everything that he'd already known.

House was tempted to bring it up to Wilson, but there was something about watching both of them, just sitting back and studying the two as they interacted, that was more appealing to him. It was like watching one of his soaps on TV, except /much/ more entertaining. If nothing else, he loved that expression that would cross their face when they would notice him watching, that look that said 'I know, that you know, that I know, that you know we're going off and fucking in the stairwell'.

Their fights were something to behold, the angry glares they would exchange as Wilson would pass the conference room or the way Chase could gnaw through three biro pens in a week. It was times like this that House was /really/ tempted to say something, not because he cared whether they were having a spat, but because both of them would act like idiots.

It was during those fights when Chase was silent, a comeback poised and ready but never actually let loose and Wilson would come into his office and actually try and ask 'how his day was'. They had dropped that small talk years ago and Wilson only pulled it out when something was disturbing him. House had heard enough of it when his wives left; he didn't need to hear it now.

Their fights wouldn't last long though, one of them eventually gave in and the rumors once again spread about the places /not/ to go 'unless you were into that sort of thing'. Soon after that, those slight, unnecessary touches would begin and those quick, almost shy glances would be thrown out as if they were nothing.

Eventually, he knew he would have to say something, this really was too good to keep silent about. He would laugh at Wilson and ridicule Chase, but only for a while. Affterward, he would tell Wilson that he was damn lucky and occasionally 'go easy' on Chase at Wilson's request. It wouldn't last though, soon or later he would be dealing with more small talk from his friend and watching as Chase gnawed through more biro pens then was probably healthy. It wouldn't last long, maybe a week or two, then everything would return to being perfectly normal. The only difference was, Chase and Wilson would never look each other in the eye.

They should consider themselves lucky that House only gave them passing glances.
