Context: She and Colton had been the perfect couple in school , named prom king and queen , but he could see in her now a faint disillusionment , a pride in the way she had told him her name was still Kaufman . He and Colton had never been friends , though he knew Elise had never understood their rivalry . Colton , he knew , genuinely hated him , for the barbs he 'd always laced their conversations with , and for the way he 'd watched Elise , all through school . He had never totally hated Colton , and the old animosity had softened to playful barbs - for Jack , at least - when he had realised that Colton had no memory of tormenting a small blonde boy in grade school .
