Our reading
An editorial interpretation.
The words reveal the Marauder’s Map, turning apparently ordinary parchment into a guide for secret journeys. The joke is that a solemn oath, usually a promise to behave well, becomes an admission of mischief. Paired with the map’s closing words, the phrase gives an adventure its own beginning and end. The attribution records an incantation used by several characters, rather than a unique personal declaration.
