Two or more instances of the same character in the same scene. The instances should be completely identical and wearing the same outfit.
Do not use this tag for a character who is a clone of another character, unless both are present in the scene.
Not to be mistaken for multiple_views, where multiple images of the characters are independent, and do not react to one another, or inhabit a common environment.
