In a cavern deep below the city, he worked. He had made his home here, carving it out from the rock face and decorating it with stringed lights, pretty cloths, and furniture he and Seirgo stole. He was proud of what he built, what he could create and sustain in the cave that no one but him and his friends knew about. He felt joy when his house was added to by anyone he allowed to visit, from the paintings that Zoe did on the side of the house of landscapes, to the beautiful tapestry of a jellyfish that Django hung up inside the living room. He was most proud of the peach tree that rested in the middle of the make-shift yard that stretched between the house and an underground river Diego forced into existence.
The peach tree was a gift from Siergo, well the bag of peaches he gave Diego was. But the knowledge that Siergo needed to return to Italy for an extended time was hard on the cyborg. With the last of his peaches he decided to try to make the gift last longer, planting it in the soil outside and soon enough the tree towered tall in the cavern. No need for actual sunlight, only Diego's care was enough for it to thrive.
And now in his safe haven, his home of only his and his alone, Diego worked in his lab to make a chemical that would be able to produce not only flesh, but an entire human system around a living skeleton. This would be on a whole new level of science, but the cyborg had no doubt in his abilities to do so. All he had to do was add a few more simple ingredients and it would be complete, and Django would finally be able to join him and Zoe in civilization. How easy it is to take that simple privilege for granite.
Of course, after everything is set and ready, Django himself will have to go through testing. The sudden gain of a nerve system could easily take a number on him, and the taste of food as well as the ability to breath would be something else entirely for someone who was born a skeleton and never had been anything else. Diego figured that he could just set up some small samples of basic tastes like sweet and salty, then expand further into actual meals. It will be a slow process, but one worth wild in the end to give Django a way to experience pleasures the cyborg once overlooked himself. He was surprised with how sad he felt when he first learned Django had never seen a movie in theaters before, or eaten at a restaurant.
" I heard of this all you can eat noodle bar thing?" Django said to him on the skyscraper roof one Tuesday night. "Like, you go and get your noodles and your fixins and stuff and they cook it right in front of you on this big grill?"
" I know the place you're talking about. Altan Noodle Bar, right? If you never have been, we can go now, I am kinda hungry." How foolish he felt saying that. One look at Django told him everything he needed to know.
A few weeks after that a band Django loved was playing a show, but security was on top of their work and soon enough superheros were getting a free show while Django sat on the top of a nearby building wishing he could, for once, just be allowed to go where humans could. Diego felt horrible being able to go in by just a simple flip of his arm to look like a human limb and his robotic red eye turning into a pair of glasses.
It was a week after that Django asked if he would be able to give him a human form in some way. He had nothing to give in return for something that would be as valuable as this, but he was hoping for some good. And how could Diego say no? Villains may be evil, horrible, monstrous people but they all still made choices, and Diego decided to make a choice. He didn't have to watch his friend live a life without the simple pleasure of walking down the street with no one giving a care, and that was Django was to him, a friend. One he could trust, and one he knew would lay down his mystic guitar for him if it meant an ounce of suffering prevention on Diego's side.
Diego wasn't about to fail him, even if it meant picking up a knife from his kitchen and going to the lab. It was going far, at least for some, but to Diego it was just science as he drew the blade across his human palm and watched as the opal liquid bleed out from the cut and into a beaker. Finally, the mixture was complete…
and what Django didn't know wouldn't hurt him.
