"If only I'd come here with my hand and immediately after it happened, then," there was light teasing amusement in Luke's voice before he sobered, shaking his head, "but that sounds like it's something of a feat and takes way too much energy from you, so just for the best I didn't."

It wasn't like he was particularly upset at having a prosthetic anyway - having lost the hand, and being upset at who did it? Yes, of course. But he didn't mind the cybernetic itself.
