Mordin forges onward, oblivious to the look on Steve's face. He has always been better with alleles than expressions, anyway. "Clearly advanced techniques. Hope you don't mind me asking- who conducted your modifications?"

Someone who knows their way around a DNA helix has clearly been to work on Steve, and Mordin wants to know who. Preferably so he can meet them and chatter about research while discussing Steve's body like it was a piece of artwork.
