Percival helps Sophie put together some of the pieces she’s missing. Interestingly, he implies that the Witch cursed Sophie believing that she was Lettie—highlighting that the Witch, while powerful, doesn’t know everything. And again, Percival’s almost instinctive desire to protect Howl suggests that Howl is, to put it simply, someone worth protecting. He’s not an evil person who just deserves to die, as Sophie sometimes thinks. Rather, it implies that many people see Howl as being on the side of good, and as someone they should help continue to do good.
