Let's save the chapter! Perhaps if, the old lady while grabbing the girl, unintentionally tore the girl's necklace, which was made of small colored spheres, and some of them fell and spread across the subway platform, when the girl got rid of the lady and tried to run for not to miss her train, she slipped on one of these spheres and hit her head on the floor.
This would be a much more plausible option, wouldn't it? 😋
Warning!!! Please metro security guards, collect the other spheres to avoid further accidents !!!! 😝
She could also have broken a bracelet (less spheres to roll in the platform), made with six spheres of different colors, which could mean the colors of the six spirits that she will have affinity later on ...
Laughs!!! Sorry for making a mess. Let's see how the history develop 😅
