so basically, the spirit of christmas yet to come is different as firstly how scrooge greets the spirit, hes the one to talk first and offer himself. he’s also scared, something about this knees shaking??. the spirit holds out a hand but doesnt speak whereas the others speak. we don’t see the spirits face whereas we do with the others. the others represent light and wealth whereas this one is black and dark. the spirit brings scrooge to 4 places i think, the cratchits, caroline and her husbands house, the grave robbers and then scrooge’s grave himself, this literally might not help but i hope it does
