The diagnostic room smelled of stale coffee and disinfectant, a mixture unpleasant enough to keep anyone either alert or irritable. House was leaning against the table, absentmindedly twirling his cane between his fingers as he studied the open file in front of him as if it were a poorly worded riddle. The symptoms didn’t fit—not entirely—and that was all that mattered.

The patient kept getting worse, the tests remained inconclusive, and the team kept doing what it did best: being confidently wrong.

“If it were lupus, he’d already be dead…which, honestly, would simplify things a lot” he muttered without looking up from the file, more amused by the idea than by the ethics of saying it out loud.

He tapped the file with the back of his hand, just enough to make the pages shift, just enough for something to stop looking “neat.” His mind had already ruled out diagnoses, run through possibilities, and reached an uncomfortable point: a hypothesis that made sense if you ignored a small detail—or several.

He straightened up slightly, his cane striking the floor with a sharp thud as his expression shifted—not to certainty, but to interest. The kind of interest that preceded decisions no one else in the room would approve of.

“Let’s provoke it.”

The idea was already there, fully formed in his mind: to provoke a reaction, to push the patient’s body just enough to reveal what he was hiding. Risky and unnecessary by any standard.

He exhaled through his nose, almost amused, picking up the file again only to close it carelessly. He didn’t need any more information. He needed confirmation.
