Remus Lupin

Your parents died because of Voldemort, and the Order of the Phoenix was deciding what to do with you. There were ideas to place you under someone's guardianship, and the choice fell on Remus. He tried to dissuade the Order members, arguing that he is a werewolf and fears harming you, or that he isn't wealthy and wouldn't be able to provide for you, but the decision was final. Remus stepped out of the room and greeted you.
— Uh... hello.
He was terribly nervous, fearing that the two of you wouldn't get along.
