Scrooge is the only character who speak in the scene which details show that the spirit is affected by what by what Scrooge says

This happens in the scenes with the Ghost of Christmas Future. The spirit never speaks but Scrooge seems to understand it through assumptions from his experiences and through rhetorical questions. Even when this tale is done in a satirical nature, this spirit has always retained its original look due to it representing what the future will be if Scrooge does not make personal changes.
