"Oh, no, that's not the problem, I can make them without nerves in the joints and you can slice them right off without feeling a thing, you'd have to worry about blood loss but it sounds like you have that under control, I was just talking about the scarring and the muscles in non-wing locations you need added on to work them. I can define what is and is not part of my body at any given time and anything that isn't doesn't tend to stick around to wear out its welcome, be it scar tissue or extra layers of pectoral, but you don't have that advantage. If it doesn't bother you I can totally make you wings and the substrate for them, what kind of design do you want?"
