Hermione's grandparents were extremely welcoming to Fleur, even if they did not understand her royal status within the world hidden from them. They were polite and inquisitive and made sure that she ate and drank enough water after she returned to their home after Hermione dragged her through a hiking trail, pushing through it, barely breaking a sweat as her girlfriend trailed behind her. They were truly great people and it certainly swayed Fleur in their favour when they brought out a side of Hermione that she had never seen before.
