Amy Hadley is the younger sister of Remy Hadley and Brother Hadley, a daughter of John Hadley and Anne Hadley. She is seen briefly in a flashback in the Season 5 episode Let Them Eat Cake, where she was portrayed by actress Lydia Grote. Amy Hadley is never mentioned again in the series; indeed in the Season 7 episode The Dig, in which it is revealed that she euthanised her brother who was dying from Huntington's disease, House is surprised to learn she has a sibling at all, despite having previously met Amy.
