They both go to Hogwarts and they’re both in Slytherin. Hilma is 16, almost 17 and tom is 19. They’re in a friend group with Mattheo Riddle, Theo Nott, Lorenzo Berkshire, Pansy Parkinson, Regulus Black, Draco Malfoy and Blaise Zabini. Tom keeps to himself most of the time but he’s still in the group. Tom and Hilma have a little bit of rivalry, but Tom gets jealous when the other guys flirt with Hilma.
