Author's Note: I was ruminating on how one would combine Harry Potter and Star Trek '09 and this was what happened. Before you start reading, you should know that I will not be pairing Harry with any of the Star Trek '09 characters and pairings that are implied or shown will be slash (this won't be a surprise to anyone that has read my HP or ST09 fics). Enjoy!

Jim turned from the door of the shuttle for a last look, and watched as a brunet materialised several feet above the ground before dropping with a soft thud. He was down the steps in seconds. "You all right?" he asked holding out a hand.

"Perfect," he huffed, slightly winded, accepting the hand easily. Jim tugged the wild-haired teen to his feet. "Transporter settings off?"

"Something like that," he murmured, his eyes flitting across his surroundings before settling on the shuttle.

"Joining us at Academy?" The teen nodded. Jim grinned. "Jim Kirk."

"Harry Black," he replied with a wry smile. He followed the blonde back up the steps and onto the shuttle.

Harry tugged sharply at his jacket, pulling him up short before he conked his head on a low clearance beam. "At ease gentleman," Jim remarked cockily to the Cadets from the night before. "Thanks," he murmured as they settled in a pair of chairs, the blonde throwing a charming smile Uhura's way.

"Don't mention it," he replied, clipping himself into the harness. His eyes shifted to a female officer having a debate with a dishevelled man. The woman won, and the man settled on Harry's other side.

Jim leant around him. "I think these things are pretty safe," he murmured.

"Don't pander to me, kid," he retorted.

Harry's brows furrowed as the older man listed maladies and events that could befall them. "You don't have to worry about the integrity of the hull, and as long as they give her a tune-up within a couple of trips, they won't have any technical issues," he remarked casually. Both his companions blinked at him. "I'm a flyer," he remarked, lifting a shoulder in a shrug.

Jim grinned at him. "Jim Kirk, and this is Harry Black," he introduced.

"McCoy, Leonard McCoy," he replied holding out his flask to Jim. "You even old enough to drink kid?" he asked Harry.

"I am where I come from," he answered honestly. Jim grinned and handed him the flask. He took a swig. "Had stronger," he stated and handed it back to Leonard. "Why are you here if you have such a problem with space?"

"Don't have much choice, the ex-wife took the whole dang planet in the divorce. All that's left is my bones."

"And your charm," he retorted. Both his companions snorted. The shuttle took off and he licked his lips. "Jim," he spoke in an undertone, "I'm not really-"

"I'll take care of it," he interrupted confidently. The teen blinked. "All I need is access to their system," he added, lowering his voice further.

"Thanks."

"Don't mention it."

Jim and Harry curled up beside each other on the end of a double bed while Bones plodded about the room unpacking. "Why don't you want to take the leadership course?"

"I don't want to Captain a ship," Harry answered easily.

"You were open to anything until you looked over the syllabus," he pointed out.

Harry opened his mouth. "What's the real reason?" Bones demanded.

The teen sighed. "Kobayashi Maru," he stated. He saw their confusion. "The only way to pass the syllabus is to take the Kobayashi Maru test. It's unbeatable."

"Nothing is unbeatable," Jim remarked.

"This test is designed to be unbeatable," he stated. "It's one thing to sacrifice myself, but it's another to cause the death of everyone with me," he remarked with a shudder. "Even if it is a simulation."

"What are you running from?" Jim asked, concerned.

"What makes you think I'm running from anything?"

"I've never known transporter technicians to be out by more than an inch," he stated, aware of Bones' intense focus. "He not only landed on his back, but from high enough to be winded," he informed.

"Are you all right?" he asked, concerned, by the teen's side in a second.

"I'm fine," he reassured.

"Please tell me you didn't make use of experimental technology?"

"I didn't," he promised honestly.

"Then what was it?" Jim demanded.

"I can't tell you."

"Give me one good reason."

"I can give you two: you'd think I was nuts, and I can't."

"You can't?" Bones repeated.

"I've been sworn to secrecy since I was eleven. I might not be on the same planet, but I'm pretty sure it still applies."

"Then what can you tell us?" Bones asked as he settled on a chair opposite the pair.

"I've just turned eighteen, I'm practically blind without my glasses, I'm a fast runner, and I had an alternative education. But I'm a quick learner, so if you could get me all the information I should know, I'll catch up soon enough." Jim nodded.

"Any allergies?" Bones demanded. Harry shook his head. "Any problems with your heart and lungs?"

"Nope, fit as a fiddle except for the eyes. And being scrawny."

"Don't worry, that's on my list to fix too." Harry startled. "You'd be amazed at the technology at my disposal."

"Isn't that an abuse of resources?"

"Not if I nominate myself as your official physician," he replied with a smirk.

"Can you even do that?" Jim retorted.

"Well, since both of you opted out of having a physical check-up, you haven't been assigned a physician. So once I've had my detox, and officially been added to the register of attending physicians, I can. As long as the two of you don't object?" They shook their heads. "Good."

"You opted out too," Jim pointed out.

"Like I said, I'll be having a detox, so I'll get a check-up then. No point wasting time and resources."

"Okay," Jim remarked, waving that away. "Now we can focus on the personal stuff," he spoke with a grin. Both his companions blinked. "What's your favourite colour?"

"Silver," he replied immediately. "And green," he added hastily.

"Black isn't your real last name is it?" Bones drawled insightfully.

"It technically wasn't the name I was born with, but my godfather named me his heir, so after he died all of his assets came to me. That would include his last name," he spoke with a grin.

"So what's your real surname?"

"Potter," he huffed.

"You're right, Black is better," Jim replied with a grin.

"Bones?" Harry asked before Jim could continue his interrogation.

"That's going to stick isn't it?" he sighed.

"Yes," both his companions replied.

"Fine," he huffed. "Yes Harry?"

He licked his lips. "Are you okay with me sharing a room with you?" he asked softly.

"You going to be bringing company over?"

"Besides him," he spoke, jerking a thumb in Jim's direction, "no."

"Going to make a mess?"

"Don't think I could even if I wanted to."

"Going to come back in the wee hours of the morning?"

"Not in the way you mean," he answered slowly. "I have a problem with insomnia, but I've had roommates before, so I've had practise not disturbing others with it."

"I'll work on that too," he murmured. "I think we'll get on just fine."
