These are two are Summer and Winter. They are two of the seasons. There's also Autumn and Spring, but they are for another story (possibly in the form of an entry). The seasons are all sisters. Spring and Autumn get along great, but, Summer and Winter can't stand each other. So we find them in a moment where they started fighting and Summer just pushed Winter over while yelling at her.
