She knew it bothered him, coming from her, though when his best friend—no, his parabatai; she had learned since coming to the Institute that these were quite different things—Jem did it, Will seemed to take it as a term of affection.

She had never called him “William,” only ever “Will” or his Welsh name, Gwilym.
