A voice over/ narration is when one person hears the voice of a character or narrator speaking but the character in question is not speaking those words on screen.

An example of this could be in “YOU” during Joe’s narration of his thoughts about the other characters. Narration could be used here to give insight into the characters thoughts and ideas and let the audience know certain factors that other characters on screen don’t. Such as when he describes what he thinks of the new people he met.
