EDITED 19/9/13

"Prowl?" Bluestreak called from the door.

Said mech looked up from his desk and gave the younger Praxian a stern look.

"Prowl, sir." Bluestreak hurriedly corrected himself. "Can I come in?"

The tactician nodded and gestured tiredly to the chair by his desk. "How can I help you?"

The small doorwinger crept into the room, but didn't sit down. "How come you're still here?"

Barely glancing up before refocusing his attention on the reports on his desk, Prowl said, "I have work to do."

"But sir, the work shift is over. Sideswipe is throwing a party in the rec. room! You should come!"

"Was this party authorised?"

Realising that it most likely wasn't, the younger Praxian paused. "Uh... Well, I'm not sure because Sideswipe never said, he just said that he was throwing a party and that everyone is welcome so I thought that this would be a great opportunity for you to be social! And I know it's not authorised and you like things to be by the book, but Optimus will be there, so I don't think it's too illegal-"

"Optimus will be there?" Prowl repeated, raising an optic ridge.

"Yes, sir. And I think he would agree with me that you're spending too much time working."

Prowl waved the younger mechs concern away. "I am finishing up here now, but I am not going to a party."

The younger mech's doorwings sagged, but he nodded. "Alright. Maybe another time?"

"Perhaps." Prowl said stiffly as he watched the sniper leave the room. Once he was gone, the tactician allowed his stiff posture to droop slightly. He hadn't been able to focus on his work properly at all - his processor was too full of Jazz.

Jazz, who had helped him. Who had saved him. Who was a Decepticon. Who no doubt killed and tortured countless of Prowl's allies. Who was completely insane.

Considering he had only met the mech once a week ago, his thoughts were strangely focused on the 'con.

With a groan, Prowl slumped forwards and rubbed his faceplates tiredly. Bluestreak was right - he was working too much. He stood up and stretched, ignoring the crack of his spinal struts as they snapped into place. Deciding he need some fresh air, Prowl exited his office and made his way outside.

He didn't encounter anyone in the halls as he walked - most were probably at Sideswipe's ridiculous party. He could faintly hear music pounding from the direction of the rec. room.

The minute he stepped foot outside the building, he relaxed. There was something about standing under the smoky sky and letting the air clear out stuffy intakes that soothed Prowl. He made his way over to a bench and sat heavily. The tension bled out of his frame as he looked up at the stars, realising for the first time how tired and overworked his processor felt.

He wasn't sure how long he sat there, but he eventually became aware of something. The feeling he was being watched came over him, and his spinal struts started to tingle.

"Hello?" He called, scanning for spark signatures. The scan told him there was no one there, but instinct told him not to let his guard down. They could be using some kind of shield, or signature distorter. "Show yourself."

Still nothing.

Knowing that he wouldn't be able to relax anymore, Prowl stood from the bench and prepared to return inside.

"Leavin' already?"

He whirled around so fast he almost fell over. Fingers twitched as he went to reach for his blaster, only to still once he realised that he had left it in his office. "Jazz."

The silver Decepticon tilted his head. "Ah, ya figured it out."

Prowl said nothing, simply taking in the mech. His battle computer went wild, screaming all sorts of statistics and plans.

Humming softly, Jazz jumped down from the metal beam he had been perched on. "How?"

"How what?"

"How did ya find out who Ah was?"

"We obtained some Decepticon intel." His words were stiff.

"Huh." Jazz hopped onto the bench Prowl had vacated and lay across it. Even when sprawled, he looked sinfully graceful and dangerous. "Ah had hoped it'd be more dramatic than that."

"Why are you here?"

"To see you, o' course." The red visor flashed. "Ah told ya, you fascinate meh."

"This was dangerous, even for you. Are you planning to steal Autobot intelligence?"

"Can't steal what don't exist." The words were sang out mockingly.

"To kill me?"

That caused the dangerous mech to perk up. "Now why would ya think that?"

"Because you are a Decepticon."

Jazz wrinkled his olfactory sensor. "Labels. Ah may wear the badge, but that don't mean Ah follow mindlessly. Ah'm mah own mech."

Every ounce of tension that had left Prowl's body had returned tenfold. His battle computer couldn't comprehend why this high ranking Decepticon would come to the Iaconian Autobot base, invariably placing himself in danger, and then lounge around as though he had been there his whole life. And all, apparently, to see Prowl. "I do not understand why you are here."

The saboteur stretched out his slim body leisurely, like a cybercat. "Ah told ya. Ah'm here ta-"

"No, I mean why are you really here?"

Visor flashing at being interrupted, he offered Prowl a predatory grin as he stood fluidly and stalked towards the tactician. He invaded the taller mech's space until Prowl was forced to retreat into a wall. Grinning, Jazz caged him in with his arms and leaned in close so that their nasal ridges brushed off each other. "Sometimes, a certain bot catches my fancy. We interface, Ah kill them, and then Ah move on. You, cutie pie, happen to have caught my fancy."

Prowl frowned at the uncomfortable proximity. "So I simply will not interface with you, and all will be well."

The Decepticon threw back his head and laughed. "Ah like you." He grinned, his face returning to its extremely close position. "Ah think ya will interface with meh, Prowl. Not today, maybe. But ya will. It'll be a real shame ta have ta kill ya, but Ah can't have anyone developin' emotional ties, ya know?"

Staring dispassionately at him, the tactician nodded, "Killing seems to be one way to loosen emotional ties."

Jazz grinned and leaned closer. Their olfactory sensors were firmly pressed together now. "It sure is. Ah'm sure ya'll enjoy it. Everyone else did."

"I am not 'everyone else'." Prowl pointed out with a hint of irritation.

"Oh, Ah know. That's why ya interest meh. But Ah think your li'l Praxian friend is right. Ya need more social contact. Not necessarily with anyone else other than meh, of course."

Optics ridges drew together in a deep frown. "How long have you been spying on me?"

"Spying? Nah, Ah'd call it 'observing'. And since Ah met ya, pretty much. You're a very straightforward bot, cutie pie. Ya stick to a schedule. Makes it easy ta follow ya."

"How have you been here for a week without being detected?" Prowl avoided thinking about how one of the most dangerous Decepticons ever had just called him 'cutie pie' lest his processor crash.

That earned him a snicker. "Ah ain't head o' Special Ops for mah good looks. Although it might have helped."

Although the tactician would never admit it, the sabouteur was exceptionally good looking. "It seems your position was well deserved." Jazz paused, seeming honestly surprised and taken aback at receiving a sincere compliment. Prowl noticed, and raised an optic ridge. "You don't get complimented often?"

"That hardly matters." Jazz snarled, pressing painfully into the taller mech's side, where a main energon line was located.

"I simply think it strange you do not get complimented all the time." The tactician spoke quickly.

Jazz paused, before giving him a grin like sugar. "Aw! You're so sweet!"

The tactician made a mental note to be cautious around the clearly unstable mech. Not even his battle computer could help him in this situation; the Decepticon was too unpredictable.

"Prowl? Are you out here? I just - oh! Am I interrupting something?"

Startled, Prowl's head whipped around to see Bluestreak pausing in the entrance to the garden. He had a moment of panic: He couldn't let Bluestreak come to harm.

The younger Praxian smiled politely at Jazz. "Who are you?"

Unable to figure out why Bluestreak wasn't fleeing in terror, Prowl looked back to Jazz curiously; The glowing red visor had turned a cerulean blue - Autobot blue. His Decepticon spark signature was still hidden, but now an Autobot signal was being broadcasted from him.

The Decepticon smiled sweetly at the little Praxian and said the first name that popped into his head. "Ah'm Rumble. Me an' Prowl were just talkin'."

Bluestreak glanced at them: their bodies were practically entwined together. "Right. Well.. Uh.. I hate to interrupt. Go back to 'talking'. I was just going to tell Prowl that I wasn't going to be at the party anymore, if he came looking."

Noticing something different about the gunner,s demeanour, Prowl narrowed his optics suspiciously. "Where will you be?"

A brief look of hesitation flashed across the young mech's face, before he smiled nervously. "Um... Sideswipe and Sunstreaker invited me back to their quarters-"

"No." The tactician interrupted immediately, glaring at the younger doorwinger. "Absolutely not."

Bluestreak's face fell. "Aw, Prowl. Please? We're not going to DO anything."

"You think the twins invited you back to their quarters after a party so they can do nothing with you?"

Meanwhile, Jazz was watching the entire exchange with an air of total amusement. He hadn't expected Prowl to be so protective of his fellow Praxian, and yet here he was, acting as if Jazz didn't exist. That thought made the saboteur frown - Prowl's attention should have been focused on him. But still, he couldn't help but be amused at the tension in Prowl's frame as he glared at Bluestreak.

The younger mech was scowling furiously. "So you can be out here and do whatever the Pit you want with Rumble against the wall, but I can't go to my friends quarters?!"

The tactician allowed a growl to escape him. "Bluestreak!"

"Spectrum is looking for you. He probably wants to interface with you too. I bet he'd let me go to Sides'n'Sunny's.." Bluestreak grumbled as he walked off.

As much as Prowl felt the need to sternly reprimand the younger Praxian for his disrespectful behaviour, Prowl was glad Bluestreak was out of harms way. He still felt the need to let Jazz know that he didn't usually allow his troops to speak that way to him. "Bluestreak never acts like that. Please excuse him."

Jazz couldnt stop himself from laughing, and he shook his head. "A very dangerous Decepticon has you pinned up against the wall, and you're apologisin' for the behaviour of a youngling. Who's Spectrum?" Jazz leaned in close suddenly, giving off an aura of territoriality.

"Head of Special Operations." The tactician murmured, leaning back as much as he could.

"So Ah'm in competition with my Autobot counterpart. Ironic."

"Competition?" Prowl asked, failing to understand.

The saboteur grinned, finally allowing his blue visor to darken back to blood red. "Yeah. Didn't li'l Bluestreak just say that this Spectrum is after your affections?"

"I must have missed that part." Prowl said dryly. "Blue suits you better than red."

His grin widened, and he tapped his visor. "Really? Ah think blue makes meh look washed out."

"I don't think so."

"Thanks." Jazz snickered, before eyeing the Praxian up from the corner of his vision. "Ya know that li'l Bluestreak is gonna go an' stay with them twins anyway, right?"

"What? I gave him orders not to."

"He's young. He'll ignore them." Jazz's leg lifted and brushed against Prowl's, earning him a scowl from the tactician.

"Stop that."

"Stop what?"

"Stop provocatively rubbing your leg off mine."

Grinning, the Decepticon leaned in so that their foreheads were touching. "You have such a way with words."

"I am glad I impress you." Prowl said stiffly. "Please retain some space between us."

Jazz leaned in so his mouth was level with Prowl's audio. "But where's the fun in personal space?" He whispered, grinning at the small shiver his voice elicited from the stoic tactician.

"I believe," His voice was strained, "that it is time for me to go to berth."

"Lead the way."

"On my own." The tactician growled out.

Pouting playfully, Jazz stroked one of the tall Praxian's wings. "Darn. Guess Ah'll have ta wait for another time, huh?"

Flicking his doorwing out of reach, Prowl said nothing as he pushed on Jazz's chassis. With a laugh, the saboteur stepped back to allow Prowl room to move. As the tactician moved away and made for the entrance of the building, he said "You should leave now."

"Ya don't really want me to, though."

Clearly, this mech was delusional. "Yes, I do. Otherwise, I would not have said it."

Jazz grinned and sauntered after him as Prowl turned and walked inside. "Ah ain't gonna leave, ya know. That would be like admittin' defeat. And Ah've never been defeated." The saboteur said, easily falling into step beside Prowl.

"You cannot stay here forever."

"No, Ah can't. But Ah can stay here 'till Megatron calls meh back."

Scowling internally, the Praxian let no emotion show up on his face. "Where exactly do you plan to stay?"

"Your quarters?" The suggestion was accompanied by a lewd grin and wandering hands.

"No." The wandering hands were slapped away.

The unhinged Decepticon laughed at the blunt answer. "Didn't think so. Don't worry, Ah'll find somewhere."

"And how do you know that I will not simply tell the others that you are here?"

"Ya didn't tell 'em it was me that helped ya."

There was a brief pause. "No, I didn't."

"Well then." Jazz said simply, as if that was the answer to all Prowl's questions.

The doorwinged mech frowned to himself as his battle computer went into overdrive. He couldn't lead Jazz back to his quarters - that would be suicide. The Decepticon could easily kill him in his recharge.

As if he could read his mind, Jazz spoke up. "Ah've already been in your room. Ah know where it is."

That was one thing off Prowl's mind. He turned to frown again at the Decepticon. "What will it take to make you leave? You want me to interface with you?" He knew that putting himself in such a vulnerable position with a Decepticon was life threatening and unbecoming of a senior officer, but he would do it if it meant getting Jazz to leave.

Jazz turned and met Prowl's stare through his visor. "No." He said simply.

His logic centre faltered for a moment. "No? But you said-"

"Ah know what Ah said." Jazz interrupted as they reached Prowl's door.

Instead of entering the code, the tactician just frowned at Jazz. Sighing impatiently, the Decepticon reached out to the control panel; Prowl watched as he successfully hacked into the system and opened his door.

Humming and smiling to himself, Jazz looked around as he walked into the large quarters, nodding as he went. It was how he had imagined it; blank. There were no personal effects at all. It didn't even look like it was lived in. "Surely you ain't disappointed that Ah'm not gonna frag ya tonight?"

"Of course I am not." The tactician bristled. "I am simply looking for the most effective ways to get you to leave."

"Ah'm not leavin' 'till Ah get what Ah want." With the grace of a dancer, he pounced on the berth and relaxed his body.

"And that is?"

Jazz grinned and tapped his nasal ridge secretively. "Hush now. Time for recharge."

"Get off my berth."

"Why?" Jazz pretended to look surprised. "There's plenty'a room for both of us!"

"I just met you."

"Untrue. Ya met meh a week ago."

"We do not know each other."

"Ah know ya quite well. Ah looked through your file after Ah first met ya and Ah've been watchin' ya for a week. Ah think it feels like we've know each other for ages."

It was quiet for a moment; he almost agreed with Jazz. It did feel like they had known each other for ages. "We are not sleeping in the same berth."

"Fine. You can sleep on the couch."

Prowl actually sputtered in outrage. Emotionless, stoic Prowl sputtered. The visored mech grinned at the sight. "It is MY berth!"

Apparently deaf to the complaints, the Decepticon stretched out leisurely, draping his frame over the berth in an extremely provocative way. Prowl did his best to glare rather than stare. "C'mon, cutie pie. Ah swear Ah won't hurt ya in the middle o' the night. Ah wouldn't do that."

Unfortunately, Prowl was now having an extremely hard time not staring at Jazz's attractive frame. "I don't trust you."

A frown appeared behind his visor, unseen by the Autobot. It was rare that someone could hold up so long under his charm, and Prowl showed no outward signs of bending. "Fine. Sleep on the couch."

"Jazz-"

"Ah offered the berth and ya wouldn't take it!"

"Why don't YOU take the couch?!"

Jazz couldn't stop the grin that spread across his face as Prowl began to lose his patience. He had been observing the tactician for a week, and he had never come close to losing his cool, even when he was dealing with the two berserker twins. But now, with so little effort, Jazz was causing him to get angry. And Jazz found an Angry Prowl to be an Attractive Prowl. "'Cause Ah'm a guest, silly. It would be rude."

All sorts of social protocols began popping up in his processor, and Prowl hissed as his logic centre pointed out the truth of that statement. "Fine." He said stiffly, walking over to the couch and lying on it. "Good night."

"Nighty night." Jazz grinned from the berth, his visor bathing the room in a soft red light.

Prowl's intakes slowed as he eventually fell into recharge. He wasn't a fool, of course. He kept his battle protocols online so that if Jazz attacked during the night, he would be ready. His battle computer showed Jazz at a less that 23.3% chance of attacking during the night, however. The Decepticon watched from Prowl's berth as the tacticians optics went dark. When he was sure that Prowl was asleep, he got up and silently ghosted over to the couch in order to watch him.

He had been watching Prowl recharge every night for the last week - he had almost fallen into a routine. Grinning, he climbed onto the sofa and snuggled in beside Prowl. He waited for a moment for the Autobot to online his optics and shout at him, but he didn't awaken. So Jazz waited. He knew Prowl would wake up eventually, and he couldn't wait to see the tacticians reaction to being so close to the Decepticon during recharge.

He hadn't been planning to fall into recharge beside Prowl's warmth.
