(This chapter has be half re-written, I wasn't happy with how it turned out in both quality or length. It now has an extra 600 words more, with some paragraphs being edited/re-written. Apologies for the mess.

The Ground-bridge coordinates landed the old mech right where he expected to be dropped off. He landed in a natural cave tunnel that branched out into a cavern of some sort. Small stalactites hung from the cave ceiling, adorned with sparkly flakes of energon and in the walls itself. It was honestly quite pretty. He theorized that the energon flakes could be the cause of the signal. But if (Y/n) could find the main energon source, then it would rule out that possibility.

Reaching out to the sparkly cave walls, some of the glowing flakes fell of without much resistance. It lightly stuck to his fingertips as the doctor more closely inspected said energon flakes. (O/c) optics zoned in, studying the materiel. Doc-bot's sight flickered from the walls to his digits.

"Fascinating." (Y/n) whispered to himself. Squinting a bit, his (o/c) coloured gaze drifted from his servo towards the tunnel ahead of him. The formation of the tunnel already gave evidence of an opening up further along. He needed to investigate it, reminding himself what was at stake. Possible trap or energon stash. The more time spent on thoughts, meant less time to leave before the cons found him.

Cleaning off the energon flakes from his digit-tips, (Y/n) turned to the side and pressed further into the tunnel. He took note of the walls for further reference, in case of an ambush. Sounds of the mech's peds lightly echoed through said tunnel.

Progress was showing itself through the walls, crystalline energon clusters began to appear more and more frequently the further forward he walked. Their glow softly reflected onto (Y/n)'s (a/c) armor. It was sad that such beauty would be uprooted. Like many worlds he was taken to by the Decepticon faction, planets that thrived on energon always ended up dead by Cybertronians. Mainly by the Decepticons.

Eventually, their walk through the growing energon came to a halt. It appeared that he had reached a dead end, one of witch opened into a half-dome looking cavern. The old medic's optics scanned the energon that hung from it's various locations, stepping through the entrance towards the nearby formations. Unlike the clusters before, these were much more vibrant; ready for harvesting.

As much as the aged medic wanted to study the crystalline structures for an upmost of thirty or more minutes, they knew that they were working on borrowed time. Reaching his servo to to neck cabling, he stretched the limb one way, then the other way. Prepping physically for the task ahead. They stepped towards and reached out to one of the energon crystals. With his other servo, holding a laser scalpel, he carefully and meticulously cut off a sample. Examining the cut piece as if it was the last of it.

A medic like him did try to stay on schedule, much like he had strictly done on Cybertron. However, unlike his forge planet, Earth time was still strange to him. What were mere moments to a Cybertronian, were in fact, an hour's worth of Earth time or more. Though he had gotten used to it, the lack of any interesting activity did mess with his processor from time to time.

While the old bot continues examined the raw energon sample he held, optics scanning over the glowing crystal, a Ground-bridge opened at the far side of the rocky cave room. (Y/n) could feel it in his spark with who could walk though the greenish portal. His propeller blades rattled at the possibly that it was Megatron. The medic was specifically targeted to become their Chief Medic for the Decepticons all those years ago.

The doctor snapped back to reality, focusing on a familiar winged figure approaching the ground-bridge's exit barrier. He grunted, knowing exactly who it is. Luckily, his relationship with the commander was on the better side of the Decepticon faction. Turning his body to face away from the Ground-bridge before the figure could spot him, a gravely shrill voice spoke out to the old bot.

"Miss me?~" Starscream, strutted completely out of the green and towards the medic he favoured. Posture up, wings slightly flicking and clawed servos behind his backstruts. The seeker always liked the respect and attention he got from him and thus, liked being around the older mech. Though they have had their spats, Starscream could never hate or be annoyed by him. Often preferring them with his medical needs. Not that he would ever admit it willingly.

They gave a aged hum in response "Always, Commander." Though his face showed that he didn't care, there was a slight tug on the corners of his intake. He'd rather deal with Starscream then any other con.

The air shifted suddenly when Starscream's EMP pulsed uncomfortably in responce, which didn't go unnoticed by the bigger mech. He had almost forgot the feeling of the fields, felt strange but familiar. The uncertain feelings that were emitting from Starscream concerned him however. He turned somewhat towards the seeker, optics now trained on the seeker's movements.

Starscream faltured. Starscream may have been confidant when he found the energon singal, more so now finding that the ex-CMO (Chief Medical Officer) was still alive, but having said officer face to face with himself felt surreal. The decepticon medic always had that about him, making others feel vulnerable or even frightened while under his care.

The thing was, this medic never did anything to harm him or his patients or anyone. It was a key reason Starscream liked being around this decepticon. It felt like he was finally being seen and heard when he did stick around the medbay. Though it would be hard for the Commander to admit it, but he was a tad nervous. So nervous in fact, that he remembered that Megatron would no doubt assume he was off scheming a plan to terminate him. Which meant Starscream would have to bring their medic back.

There was a bigger matter he wanted to ask about though, like how he was even separated from the faction in the first place. And how exactly he made it here to Earth of all planets. Perhaps once the both of them were back on the Nemisis, they could have a proper chat.

"I uh.." He coughed, crimson optics shifted away from his favourite medic, uncomfortably shifting his weight between his heeled peds. His wings tried to stay proud, it flicked up a few times, then hug sadly fully down from their connecting joint. Reality was setting in, not just for him, but for the medic too. At the very least, Starscream knew that the bigger bot would protect him if needed. "I thought you were, well... t-terminated."

Raised in optic ridge at his commander's words. "You thought I was offline?" His attention was now fully and completely on his fellow 'con.

"Well yes, I myself don't quite remember when or how you vanished. But you did." Commander coughed again. So much time had passed that talking like a normal bot was weird to him. Hard to admit emotions when that's what get's you terminated in war. "I'll admit, I did look for you. I mean, my trine and I scoured any trace of your presence. We uh, we couldn't find you."

Starscream was now fiddling with his clawed digits. He knew the medic wouldn't make fun of him, but it still felt out of place to willingly admit that he missed the old bot. Afterall, he had been there at his most humiliatingly lowest of times after the mentioned medic was forced to join their side of the war. Aside from making a snide remark here and there about the bot's working speed, or the common complaining about how incompetent his subordinates were, the old heli was pretty much at his beck and call. Though then again, the bigger mech did stop their leader from terminating him on multiple occasions. You would be considered a fool to even think of trusting anyone. Other than the obvious such as Soundwave and co. Starscream would rather die then to admit to anyone that he did trust the ex-chief MO.

The old mech closed his optics and sighed, this certainly wasn't how his day would go. He couldn't help but to fold his arms and pinch between his optics. Hearing his commander speak this way to him meant more than the words implied. Starscream wasn't just any seeker, he was a mech that would betray you first thing if it meant you would no longer be a threat to him. Known for backstabbing anyone if it meant he would survive. Despite the odds, there was a strange kindship he knew Starscream felt he had with him. It would only make sense, how else the bot who hailed from Iacon survive being a 'Con for so long? Such care did spread to his Trine-mates. If the Decepticon commander, who didn't trust anyone, trusted him, why wouldn't they switch medics.

To stop himself from thinking further, he should ask about them at some point. As the seekers were, he did like having the company of those 3 mechs.

Starscream hadn't said anything more after his admittance. Neither of them did. Though it had be who knows how long since either of them had last met, it felt as if it was the first time they met. The commander being scarily quiet, feeling as small as he did, having received the first blow of Megatron's unnecessary aggression. Someone needed to say something, and as much as the aged metal of a mech didn't want to, he had to break the silence. For both their sake.
