Minor Slash warning, Shounen-ai content.

The wind so cold, the night so young. The ark was quiet, for once, or at least as quiet as a base can be with giant robots inhabiting the vicinity. An over-stressed cop, second-in-command, sat near a console, Teletraan's security screens blazing in the darkened room. Prowl had inadvertently turned off his optics, his circuits throbbing and threatening to go on the fritz again. He needed to recharge; he could feel the strain on his receptors that staying awake for two nights in a row had done. He had a cup of Energon next to him, and sure, that would give him a boost, but he knew that nothing could beat a solid recharge.
His optics came back online as he heard a soft rapping on the doors. Looking up at the monitors in front of him, he saw, to his great dislike, that the red troublemaker Sideswipe stood there, waiting to be admitted into the room beyond.
"Do you have to come to me for everything that goes wrong?!" Prowl said to the doors, then grimaced as his own voice. The bot's voice even sounded strained. He growled when the silence that followed didn't give the Lamborghini the hint to go away. "What do you want?" he asked the doors in a softer tone.
The young bot entered the security room, a slightly abashed look across his normally happy face. "Sorry, Prowl, but with Optimus Prime gone for the night --" he cut off as Prowl gave off an exasperated groan.
"It's like babysitting you!!" Sideswipe jumped, backing up slightly in a frightened manner. Prowl couldn't take this any longer. Why was the crew so in need of someone to tattle to every ten minutes?! "I can't do this anymore, get the slag out of here!!" Sideswipe left without question, zipping around the corner and out of sight down the hall with Prowl's voice echoing after him like a ghost.
The second-in-command collapsed on his previously-vacated chair, exuding a deep moan as he sank, wishing that for just a few hours the world would cease to spin so that he could get some deeply-needed recharge time. Burying his face in his hands, he turned his attention back to Teletraan's blinking screens. All seemed to be in order, everyone was in their place, and the younger bots seemed to be bothering Ratchet again. He chuckled slightly as he watched the old medic chase Sunstreaker and Tracks from the-
Tracks…? He watched the Firebird curiously. 'That's odd…' he thought, never recalling the city-slicker in any of Sunstreaker's antics before, but before he could ponder the aspect much further, the wonderful silence that Prowl was just beginning to enjoy was, once again, broken by a soft knocking upon the doors.
"WHAT?!" he hissed at the doors, but immediately wished he hadn't as the doors opened to admit the slightly startled form of the third-in-command, Jazz.
The Porsche stood in the doorway looking surprised and slightly hurt by Prowl's outburst. "Prowl, you okay, man?" Prowl sighed, trying as hard as he could to settle his circuits as they were set ablaze by just the sight of Jazz, a feeling of hot warmth surging through him that he prayed to Primus wasn't showing on his face.
"Yes, yes…" Prowl responded to his younger officer. "Just… tired is all…" He watched Jazz in the doorway for a second, feeling bad that he had barked at him. Beckoning with his hand, he said "Come on, please."
The young bot entered the room, sitting in the only other vacant chair. "Thought you might have been in here," He tried to get a look at Prowl's face, but Prowl wouldn't quite look at him optic-to-optic, afraid that his face was still flushed. "Dude, you look horrible… Why don't you go recharge?"
Prowl sighed. "I wish I could, but… I have to stay here…"
"No you don't," Jazz stated matter-of-factly. "Put it on auto; Teletraan will alert us the second someone steps onto the premises," He looked at his superior incredulously. "You, above all people, should know that."
"I know, it's just…" The cop looked back at the monitors, delaying when he would have to look at the Porsche's face. "I get so edgy-" He looked down at his thigh, where Jazz's hand had suddenly appeared. A small surge of happiness went through his body as Jazz's hand lay there. He looked up at Jazz, his optics wide, and knew that he could no longer look away from the Porsche nor hide the inevitable red flush that had donned his cheeks.
Jazz looked at Prowl with a soft, almost loving-type expression. A small smile was playing across Jazz's lips and it seemed, to Prowl's surprise, that Jazz's face was slightly red in the light from the monitors behind. "Relax, Prowl…" the young bot seemed slightly surprised to see his own hand where it was. "Come on, we both need to recharge. Tell the ark it's lights out and then hit your room." He watched his superior, refusing to break optic contact with Prowl even though it set his circuits buzzing with warm feelings as Prowl watched him back. Jazz's smile must have been fading for Prowl chuckled.
"You know what?" Prowl said, sighing. "You're right. No, you're more than right, you are perfectly right." Setting the security system on auto-pilot, as he had done many times before, he got up, following Jazz out of the dark room.
When they separated at Jazz's door, Prowl felt a slight bit of longing toward the Porsche. He had had a crush on the young bot for as long as he could remember, but, for once, he would give all of his logical circuitry and memories for just the right amount of courage to tell Jazz how he felt. He was certain that his feelings were true, but was afraid of telling him for fear of tearing up their friendship.
He looked up and, with a start, found himself outside his own room. His feet had automatically taken him there while his mind had wandered where it pleased. 'Well, one thing I know for sure,' he though moodily as he opened the door. 'There's no way in hell I'm telling Jazz.' Walking into the room he stopped and cocked his head at the wall opposite him where something was written in Energon. The words gave off a very faint glow, barely visible now as its effects were beginning to fade.
He gave a start as he read the words, his optics narrowed to re-read what he could have sworn he didn't. His circuits were sent another warming trend as he re-read the words, just to make sure. He pondered and thought, racking his poor, overworked mind to try and dislodge anything that would lead him to the bot with the slanted writing, but nothing came. Deciding to think about it tomorrow, he shut his optics down, settling in for a long recharge session, but even as he slept the words ran through his subconscious along with one tiny blip of a thought that Prowl knew would never come true.

"P.S. I love you."
