Update: I'm just editing the chapters so they look better! No worries!


"Legion?" The familiar geth with the gaping hole in its chest made sudden whirring sounds as its face plates moved erratically it would have been the machine's reaction comparable to surprise and relief with the way its tightly pulled limbs seemed to relax even just the slightest. "Shepard-Commander we require your assistance." Though the mechanical voice didn't give any hint of relief away the frantic face plates seemed desperate. Held up by the connecting weave of cables and cords, Legion was bound by restrictive programs both physical and electronic that disabled his movements from disturbing the signal being amplified through its own body.

Leon Shepard was astonished at the fact of finding his geth ally in such a confining position, though he had wondered what had become of the geth once the Collector's had been stopped. Seeing the geth's body being restrained and treated as a thing put a fire in Shepard's belly, disgusted at the treatment of his friend. "They were using you to project the Reaper signal? Where is the console to get you out of there?"

The singular optic widen at the tight sound in Shepard's voice before speaking, "To the right and up there is a console where you can manually disable the locks and firewalls on my system." Shepard nodded sharply and the click as he reloaded his weapon was sharp in the air as mismatched cerulean and turquoise eyes met the single, white-blue optic of the geth, "I'm getting you out of there, Legion. Hang tight." Legion seemed to go quiet as Shepard made his way to the console, the Prothean and Tali not far behind but the geth was only focused on the human.

The human who had seemed infuriated with how it was now and as it felt it systems being released along with the cables letting free, the many processes decided to leave the discussion of this behavior for later. Right now, they had to escape before they all would be terminated. Legion immediately began to clear a path as hostile geth poured in to overwhelm them and despite the opposition they managed to escape in a fighter pod.

~~~~Later on the Normandy~~~~~~

"What was it like being connected to a Reaper?" Shepard's question was out of his usual ones as Legion took a moment to process the answer before his optic widened, "It was hard to comprehend. Even with all systems and programs being initiated….A single thought was unable to be processed by us they are far beyond our processing power. Overwhelming is a proper word for the reaction." Legion briefly tilted his head down to gaze at the large, damaged hole in chest plate before looking back at Shepard, who was leaning on a rail that surrounded the war room, allowing the large map to be placed in the center.

"Sounds like you think they're god-like." Legion's response was quick, the decision among the process almost unanimous, "They are advanced but mundane. Though we do understand now, more clearly why some would think of them as such." Shepard seemed contemplating and stood up properly before folding his arms and holding his chin briefly.

The mis-matched gaze from Shepard would be unsettling for other species that felt such things but Legion was unaffected, somewhat curious at the seriousness of Shepard's gaze at its mobile platform. Taking the moment to do the same, Legion examined Shepard more thoroughly. Shepard had gotten older despite the short time span they had spent separated since his arrest.

Slightly tanned, light skin still bore battle scars and was stretched over lean muscles of years of dedicated military service. The rare, different colored eyes had gone from a vibrant shine to something more dulled and weary, light blue hair was pulled into a short ponytail and the shadow of facial hair lined his sharp jawline and cheekbones. The short ponytail was not pulled into a strict tie like it had been usually but now it sagged, almost loose from the band in his hair dark streaks peppered the hair instead of gray like most aging humans.

By species standards, Leon Shepard was an exceptional creature with both looks many species would deem handsome and experience with military. Noting a new scar crossing from above right eye dipping down across the bridge of nose and ending just short of crossing the left cheek was large if not somewhat hideous with the light scar tissue marring his face.

"Shepard-Commander do you have any other inquiries for us to answer?" Legion's processors deemed Shepard was waiting to ask a question but when the human shook his head and simply left they felt confused. None came to a consensus for the strangeness of Shepard's actions and deemed that research would have been done quickly to avoid it affecting mission effectiveness.

~~~~~A Bit Later In Captain's Cabin~~~~

Shepard was panting hard as his body naked and hot against thin sheets as his arm jerked wildly. Moaning harshly scarred thighs quivered before a harsh groan forced his entire frame to lock up and in the dimly lit room mis-matched eyes looked briefly at a milky substance covering his hand before he sighed hard.

He laid there for a moment starring at his ceiling before sliding out of bed to clean himself up in the shower taking the moments to look himself over and ran rough, calloused hands over a firm body. Shuddering as he closed his eyes images of a finely crafted shape came into mind as a light shone from its frame.

The warm spray of the water raining down on him only pushed him further into the fantasy as he heard the soothing whirls of machinery, the smooth touch of cables brought together in such a way to mimic a body. Gasping, his hand only briefly brushed the tip of a hard cock curving at his thoughts. In his mind, it wasn't his touch but that of a gray, three-fingered hand curiously brushing him.

"Legion…" Shepard spoke softly as he envisioned the underlying cables able to release so much strength but being so gentle against his skin. Moaning at the vision of a smooth, mechanical body watching him with its gleaming, singular optic pooled the desire in Shepard's belly. Gripping his cock suddenly and jerking it hard, Shepard screamed in the rush of pleasure as his stiffened the copious spray of cum lost against the wall of the hot shower as it drained away from any evidence that it had happened at all.

Shepard's body relaxed as he leaned against the wall of the shower and with the water hitting his body he couldn't help but feel some shame at what he'd done. What he'd been doing since he got back to his cabin. When he had seen Legion being confined like that he had felt…angry. When they came back to the ship the anger had turned into a strange kind of lust and he felt he was seeing the geth in a new light.

Was it his synthetic implants? Ever since being brought back from the dead, Shepard hadn't felt right since and the events that had led to that batarian colony being destroyed to prevent Reapers from attacking had made him feel stranger. He wasn't sure what Harbinger had the doctor do to him in those hours he had been captured and unconscious but since then he had felt less human, less attached to the people he saw dying or those he was saving.

Maybe it was since Garrus had denied his advances? He had felt something more for the turian but when he confessed all he got was nothing in return. They were on better terms now having re-established their mentor/pupil roles for each other but he had felt something detach at the rejection. When Legion had joined he had only felt mild awe and admiration for the geth but now how had his feelings taken a complete three sixty so quickly?

Shepard suspected it had something to do with the nano-machines in his veins, the synthetics wiring his muscles, veins and even in his brain. What had Cerberus done to him? What lengths of his humanity had been sacrificed to his return? It was clear the Illusive Man was not afraid of giving up the human form to transcend humanity and what would have stopped him from wanting to use Shepard as a stepping stone.

Shepard felt frustrated and quickly stomped out to dry off or at least try to clear his head. Stark naked he sat at his desk only draping the towel across his lap as he froze for a moment unsure at what he was staring at. One of his eyes, the turquoise one, seemed a bit off and seemed to be a bit lighter if not brighter somehow. Leaning closer, Shepard could just make out thin lines and dark edging around his pupil, while the pupil itself looked less natural, thin lines making sharp angles and even a mechanic edge to them.

Shaking his head and almost jumping from his seat as he went straight to his bed, ignoring any thoughts from what he had just seen what might be happening to him. His emotions strained and energy almost out he collapsed into his bed to escape into the nightmares that had been plaguing him ever since Earth had been attacked.

Face plates shifting, Legion was standing in front of the cabin's door and with his sensory capabilities and honed hearing he had been able to hear if not sense Shepard's movements inside of the cabin.

The singular optic was tiny and widened as the machine's processors struggled to come to a consensus and as the geth moved back and stepped back into the elevator it was only certain in doing research further. "Analysis of Shepard-Commander's physical status requires more research. Presence of synthetic anomalies increased and human sensors have been unable to detect the proper amount.

Analysis of Shepard-Commander's actions and focused behaviors concerning this mobile platform. No data available. More research required to come to a consensus. May ask EDI for assistance in research." Legion's processors were in high confusion to the inability of detecting most of Shepard's vitals and only picking up more intricate, nano-machine interference. A worrisome prospect for the humanity left within the human(?). Possibilities opened up and more votes were taken, different approaches were possible now and the geth platform began to eliminate them one by one.

"Shepard-Commander's probability of geth infusion. 20 percent." Legion stepped off and headed for the AI core. This change of situations required more calculations Shepard's transformation was…unprecedented if not intriguing and along with curiosity something else was being roused in the geth's thought processors of more than just galactic but also somewhat personal possibilities for its core processors.

A growingly synthetic Shepard could allow for migration of programs and data, a shared conscious could be possible if not beneficial with the data Shepard's memories and actions held.

A constant allowance of data…Briefly images of Shepard's, lean, sweating body tangled in sheets came to it's thought processors, lined with the dabbling of machinery forming in Shepard's body integration and blending would not be such a far off possibility.
