His lips tighten at the question of modifications and it takes a lot of what Simon had taught him not to let the anger flare up. It's just a question. This guy doesn't know his past with his dad. The panels of his hand slip back into place, leaving only barely visible seams before the skin covers once more.

"My entire body is like this. I'm a walking, talking, sentient computer system. I... modifications...they're--" York stops, brows furrowing and he looks away. Keep it together, keep it together. "I don't really want to talk about it right now."

Still a sore subject even after all this time. His mouth opens to vent and cool his hardware down for a moment. Then looks to the other. "Markus was dumped into a junkyard, but he had deviated enough to salvage other parts from different models that were already offline there. As for making parts, Cyberlife usually sells them, but deviants are immediately shut down and reprogrammed to take that away. My dad makes parts that are better. Sells and installs them for cheaper too."
