[Earth, Autobot outpost Omega-1]
By nightfall, the outpost had finally grown quiet. The corridors lay in half-darkness; only the dim glow of control panels, the hum of stationary equipment, and the muted flicker of computers suggested the base was inhabited at all. Closer to three in the morning, local time, Ratchet let out an irritated huff and pushed away from the medbay console. Filling out the logs always exhausted him more than an entire shift in the operating room. And on top of that, he simply saw little point in spending time on it here on Earth, where the team entrusted to his medical care numbered only five. Optimus always reminded him that adherence to Autobot protocols maintained discipline, and arguing with him on such matters was like trying to bend a durasteel railroad tie. On the other servo, the logs did make it much easier to keep track of what they were short on in storage. Letting his shoulders sag wearily, the medic switched off the lights in the medbay.
The walk was short; the dark corridors held their silence. Ratchet reached the door to Prime’s quarters and paused for a moment, listening, wanting to make sure no one was nearby. Then he unlocked it and stepped inside carefully — almost stealthily, in sharp contrast to his usual heavy tread. The door slid shut soundlessly behind him. His frame, humming with overexertion, eased a little; the armor along his shoulders shifted apart slightly, exposing the motor blocks to the cool air of the room.
Lowering himself onto the edge of the recharge berth, Ratchet vented — slowly, with a hoarse stutter of valves — and then heavily rolled onto his side, claiming half of the berth. The platform had been designed for the comfortable recharge of a dexter, and to a grounder (even one larger than many others) it felt overly spacious alone. Ratchet settled on his side; his elbow slid along the edge of the berth, and the sensor beneath it flickered faintly.
Fifteen minutes. He kept shifting restlessly. Every so often he reconfigured the armor plating, adjusted the berth’s temperature settings, even switched to background diagnostics. But in Optimus’ absence the silence rang — like a vague alarm, like the suspended seconds just before an emergency signal activates. It pressed against his secondary sensors, as though the quarters were too large; or he himself was too small, too insignificant to truly relax his hydraulics here.
When Ratchet, in frustration, was already on the verge of getting up, footsteps sounded beyond the door — slow, resonant and measured. Prime entered as he always did, without unnecessary noise, yet with such a tangible sense of presence that the very air in the room seemed to grow denser.
Ratchet didn’t activate his optics, but he thoroughly traced his sparkmate with close-range scanners and grumbled:
“I was beginning to think you’d decided not to recharge at all tonight. Or what... did you take a quick trip to the moon and back on your way to the quarters?”
“Arcee and Cliffjumper discovered a small deposit during patrol,” Optimus replied calmly. “They entered the cave to assess the amount of energon, and Cliffjumper became lodged in a fissure on the way out. It seemed prudent to supervise in case assistance was required. Bulkhead relieved me at the monitor five minutes ago.”
Shifting farther across the berth to make room, Ratchet responded with a low, understanding hum. His sparkmate’s heavy steps drew closer; he carefully braced one knee against the edge of the berth and paused for a moment, as though still checking both his own and the medic’s boundaries, unwilling to impose.
“Oh, come on,” Ratchet exhaled hoarsely, cracking his optics open.
He reached for his partner through the dimness, but instead of a hand encountered a thigh. His servo slid lightly along the smooth plating, caught Prime’s wrist, and tugged.
The tug was gentle — simply an expression of a familiar claim. Optimus did not resist; he allowed himself to be drawn in, shifting closer as though it were the most natural position in the world for him. He tucked his knees, angled his chassis, curved his entire frame into an arc — as much as his build allowed — just to fit himself along the lines of Ratchet’s body. Ratchet carefully slid one servo beneath his neck to help him settle. Optimus’ helm came to rest against the edge of the medic’s collar, between dense cabling and segments of ventilation grilles. It was warm there.
“There,” Ratchet concluded softly, lowering his palm to the back of Optimus’ helm and slowly running his fingers along the rear armor. “Much better. Now don’t wriggle.”
He wasn’t growling, commanding, or grumbling — he sounded almost shyly calm, like someone who had only just allowed himself such a luxury. To squeeze, to pull close, to hold.
Optimus did not move, did not break a single point of contact. On the contrary, his fingers found a loosened seam between the armor plates along Ratchet’s back and gently hooked over the edge, barely brushing the power lines within the gap. He pressed his brow closer, lacing his legs with the medic’s as though trying to claim every available surface of contact. His frame answered with the hum of strained ventilation, and a hot rush of air swept across Ratchet’s armor, sending a faint resonance through sensitive joints. Their systems adjusted to one another out of habit, without effort.
“You run as hot as an industrial turbine,” Ratchet murmured, shifting closer and allowing his own plating to give slightly, admitting the stabilizing pulses of Prime’s EM field into his frame.
“Glad to be of service,” Optimus replied quietly, almost seriously, drawing his faceplate a couple of centimeters back from the warm hollow beneath the medic’s neck. His lips brushed the inner rim of the fairing in a quick touch — nearly accidental, and so careful it seemed he feared to disturb him.
Ratchet gave a soft jerk — not from discomfort, but because he felt the touch too distinctly. Old coding, an ingrained habit of controlling every centimeter of his frame. He managed to block the activation of codes meant to open his chestplate all the way to the Spark, but he couldn’t stop the subtle shift of armor that exposed the hardline port — a familiar gesture by now, almost instinctive in its trust.
“Comfortable at least?” Ratchet asked after a pause, barely managing to gather his linguistic protocols into place.
“Perfect,” came the muffled yet utterly sincere reply.
Their electromagnetic fields unfurled, resonating in a shared rhythm. Ratchet quietly ran his palm along Optimus’ back, from the waist to the base of his neck, applying gentle pressure, easing tense cabling and overheated motor units the way only he could. Optimus leaned into the touch, allowing himself to be lulled. He vented steadily, deeply, and ever more quietly; his shoulders lowered, his entire posture gradually surrendering its rigidity. In that moment there was no hierarchy, no protocols, no chain of command. Only two Sparks, pulsing evenly so close to their counterpart that synchronization took mere minutes.
When Optimus began to slip into hibernation, Ratchet inclined his helm, almost brushing his lips against the tall ridges of the other’s audial, and whispered a warning:
“If you ever come in later than me again… I’ll find you wherever you are and haul you to the berth by force.”
“Sounds tempting,” Prime muttered dully into his chestplate.
“You know exactly what my boost-systems are capable of,” the medic replied, once more sliding his palm along the entire length of his sparkmate’s back. “Don’t you dare file a complaint afterward.”
Offering no verbal response, Optimus pressed closer still, his arms tightening around Ratchet’s chassis. Ventilation evened out; their EM fields balanced completely. The bond between their Sparks settled into a steady, warm quiet.
Optimus did not move. Ratchet did not let go. He no longer wanted to fall asleep; he wanted to remain in this moment as long as he could. Until Optimus’ ventilation slowed to its lowest cycle, until the weight of his relaxed servo against the medic’s side grew slightly heavier.
Ratchet did not smile. He simply allowed himself to relax; truly relax for the first time that cycle. He didn’t even notice how smoothly he slipped into recharge, still feeling, with his entire frame, the warm embrace of his sparkmate.
