The line comes from Gandalf in The Fellowship of the Ring, where he reassures Frodo that a wizard is never late, but arrives precisely when he means to. The Spanish dub kept the same calm authority, which helped the phrase travel beyond the film into memes, edits and soundboards in Spanish-speaking communities. Creators reuse it because it turns an everyday delay into a reference that fans recognise instantly, and its meaning needs no explanation for anyone who knows the story.
