I've been watching Star Trek: Voyager lately (marathon on Spike) and I recently saw The Killing Game. So I wrote this, but this is funnier. And House wins all.
Wilson walked into the Clinic and up to the nurse in charge of timesheets. "Hi, yeah, sorry, but is Dr. House doing his Clinic duty right now?"

She put on her glasses, flipped through her clipboard, and shook her head. "Can't help you, Doctor. It says here that House owes fifty-two hours already. If you see him, send him in, you hear me?"

Wilson sighed and turned to go, and then stopped when he saw the end of a wooden cane disappear behind a line of patients.

He rolled his eyes and walked down that hall. A low shape moved around the other side of the line, lurking where Wilson couldn't see if he wasn't looking.

Wilson turned a corner, waited a few seconds, and then looked back. Scruffy hair ducked behind a chair.

Right. Wilson went into the stairwell, intent on losing the shadow.

When he came out, House was leaning against the wall. "I do know how to use the elevator."

Wilson rubbed his hand through his hair. "Why are you stalking me, House?"

House grinned. "Why were you looking for me in the Clinic?"

Wilson blushed and whispered, "W-well, about six months ago I was under the impression that we slept together and then started going out and that you promised to take me to dinner tonight."

House shrugged and turned to go back to the elevator. Wilson hurried to walk with him. House said, "Well, if that's the case, I guess there's no choice, right?"

As they stood side by side in the elevator, looking at the doors, House said, "And, for the record, I didn't forget. I just missed the hunt."

"That was hardly a hunt, House!" Wilson yelped.

House leaned close to Wilson's ear. "I haven't made the kill, maybe. Just wait until tonight." His tongue flicked out and along his lover's ear.

The elevator doors opened and Wilson bolted out, face scarlet and hand over his ear.
