I do not own anything. All characters belong to their rightful creators.

So this is a Harry/SLASH crossover series of one shots.

WARNING: SLASH. Go back now if you don't like it. Not beta'd.

These are the crossovers I'm willing to do. I may have forgotten one or two or three and if you know I'll write them, you can go ahead and send me a message. But remember, just because I read some of the fics, doesn't mean I can write them as well.

No longer taking prompts.

Sabaku no Sable has requested a Harry/House from house pairing with the prompt: 'Angel conquered the Devil'

Cuddy was the first to notice the change. The realisation had crept up on her after her office door opened and a cheerful whistling tune reached her ears. Cuddy had looked up, expecting to see a nurse or someone from staff, and stared incomprehensibly at the man that grinned cheekily at her.

"I had a dream last night," the man said to the open-mouthed woman in front of him, "and so far it's all come true. Minus the fact that you're currently wearing clothes."

"House?" Cuddy ignored the inappropriate remark and took in the happy and generally less scruffy appearance of the head of Diagnostics. "You seem... different."

"I don't know what you're talking about." House said, shrugging a shoulder and limping over to her desk. "I've just come here so you can sign a form to get my patient in for brain surgery."

"No- wait," Cuddy forced herself to focus, "why?"

A smirk made it's way onto House's face. "Do you really want to know?"

Cuddy sighed and pinched the bridge of her nose. "I'm your boss, it's my job to know what you're up to. We cannot afford another law suit."

House shrugged his shoulders, uncaring, and later, after Cuddy watched him leave, the woman realised that House had acted tolerable, all with a real smile on his face. She had hurriedly rang up Wilson questioning him on this anomaly, but he was just as clueless as Cuddy was.

It was with Chase that Wilson discovered House's 'secret', not that the unpleasant man did anything to hide it in the first place. Wilson feigned disinterest when Cuddy talked to him, was he was honestly worried about his friend. As much of an ass that House was, Wilson looked out for him.

Chase was hunting down his wife that he found Wilson hiding behind the nurse's counter and trying to be inconspicuous as he spied on what Chase could only guess was House and Harry, his fellow colleague. So, naturally curious, Chase moved behind Wilson and looked over his shoulder.

"What are you doing?"

Wilson jumped and snapped his head round to face Chase, nearly cracking their skulls together in the process.

Startled, Chase jumped back, staring wide eyed at the guilty-looking Oncologist.

"Don't do that!" Wilson scolded, hand to his chest as he tried to calm his racing heart while simultaneously glancing back over his shoulder at his friend who hadn't apparently noticed the small commotion behind him. Neither had the blushing Harry, apparently.

"What are you doing?" Chase repeated, the corners of his mouth twitching suspiciously.

"Nothing." Wilson said, clearing his throat.

"Oh, really?" With a raised eyebrow Chase looked past Wilson and stared at the two subjects of Wilson's bad spying. Harry now had his head tilted to the side, a cheeky-looking smile on his face that usually led to the British man to give out a smart remark or obvious innuendo. House really knew how to corrupt someone when he put his mind to it.

"Okay, fine," Wilson huffed. "I admit that I was watching House... but it was just to make sure he doesn't do anything stupid!" Wilson turned back to gaze across the room, adding, "or potentially dangerous."

Chase silently agreed with him.

"Oh, no! They're looking this way!" Wilson grabbed Chase's arm and unceremoniously yanked the Australian down behind the nurses station, ignoring the various looks being sent in their direction.

"Why does it matter?" Chase groused, face flushed a little in embarrassment.

"Because House has been avoiding me." Wilson said by way of explanation.

"I wonder why." Chase muttered, head popping up to glance at the two men who unknowingly had the attention of two doctors.

They watched as Harry leaned up, almost on his tiptoes, to whisper something into House's ear, a hand clutching the older man's shirt while doing so. Moments later a smirk appeared on House's face before straightening up and quietly saying something else.

"We should move closer." Wilson mused, a frown on his face.

"No, we shouldn't." Chase said.

"Why?"

"Because they've spotted us and are headed our way."

Both scrambled to their feet, trying and failing to look innocent while Harry and House stopped in front of them, the former's eyebrows were raised while the latter looked amused.

"Like what you see?" House queried, staring at his co-workers.

Chase and Wilson shared a panicked look.

"I think they do." Harry hummed. "Both have been watching us for some time."

"Not me!" Chase found his voice. "Wilson was the one spying on you guys!"

"Chase!"

"What? You were."

Harry's light laughter cut off the beginning of what would have been a long argument.

"It doesn't matter if you were," Harry said, eyes sparkling. "We were just curious as to why you found our conversation so interesting."

"We weren't listening." Chase said quickly before Wilson could get a word in edge ways.

"So you were watching us because..?"

"We just happened to look over at you when you saw us." Wilson stepped in.

"You've been following me for a while, Wilson," House cocked a brow. "Out with it."

"Well, we -" Wilson started.

"You!" Chase cut in indignantly.

"Alright, I was worried about your recent change in behaviour."

"And you didn't come up to ask me." House draped an arm over Harry's shoulder, pulling the other closer to his side.

"You were avoiding the issue."

"Issue?" House suddenly grinned. "You want to see what I've been 'avoiding' in conversation?"

Instantly on guard, Wilson hesitated then nodded slowly. House and Harry shared a indecipherable look before the blue-eyed doctor turned his body and ducked his head down to capture Harry's lips in a heated kiss. It took a few moments for Wilson and Chase to register what they were witnessing, indeed, nearly everyone around them had slowed to a stop to watch the rather public display, their expression ranging from disbelief to bug-eyed shock.

House didn't seem to care, his hands slipping down to squeeze Harry's arse, gaining a low moan in response which triggered more than one person of both genders around them to shift, facing flushing as they continued to watch the heated display.

Finally the couple broke apart, both breathing heavily with swollen lips and a satisfied look on their faces.

"Happy?" House asked, smirking at Wilson and Chase who were wearing identical expressions of astonishment.

"Greg," Harry scolded lightly, leaning up to lightly kiss House's jaw, "be nice."

"Aww, but Harry..." House whined.

Instead of letting House get under his skin, Harry, angelic Harry, just chuckled and patted House's cheek.

"You can have your fun later, right now however, we have a case to solve."

"How about we have some fun now?"

Harry just gave a smile. Then, with a nod of a head in Chase and Wilson's direction, Harry slipped out House's arms and headed towards the elevator, leaving everyone staring after him.

"Tease," House groused, quickly following his partner.

"I think I felt better not knowing about my boss' extra-curricular activities." Chase said after a minute of silence. From beside him, Wilson shuddered.

By the end of the day every last member of staff knew that Harry Potter and Gregory House were a couple. What most wondered, those that hadn't decided to block the situation from their minds or prayed that it would make House less of a manipulative menace, was how someone who was sweet, kind and caring like Harry could ever possibly fall in love with someone as bad-tempered, self centered and downright evil as House was. The cruel man was like the devil himself, and yet he managed to gain Harry's love.

Just finished my exams, thank goodness.
