" Unfortunately, he had no training in the healers' arts. But if he ever encountered the person who had struck Mechanic Mari like that, Alain knew he would use the skills he did have to even the score. He did not know why he resolved to do that, but he did.
At least he was fairly sure that his reason was not love. Whatever love was, other than something to be avoided. Master Mechanic Mari had shown clear signs of being concerned when Alain spoke of it, and had denied experiencing love with other Mechanics, so perhaps Mechanics also were warned to avoid love. It must be a very dangerous thing. "
