If there is some kind of loophole in the rules of magic, it might be this: the one where a person is able to be invisible until they are desired. Where they are an echo of nonexistence until they can fulfill a need, or tell a story, or be a thread in the fabric of someone else’s grand design. The flawed magic of desiring a body more than an actual person. The magical negro is so replaceable that there is nothing left of them to mourn.
