The whole shebang belongs to the narrator. There is always a narrator, regardless of how the writer tries to disguise it. Without the narrator there is no narrative, which means no story. Nothing. The narrator is orating the entire story. All of it. All the dialogue, from every POV. All the whispers of the wind and strikes of lightning and scuttling crabs. Every single part of the story is coming from the narrator. Every single part of the story. So even when you have another character "tell a story" it is still the narrator telling how that character told that story. It is all part of the same narrative.
