I'm pretty sure the doll was trying to protect him from the beginning. It saved him from a freak accident and was also blocking the door to the fire cause it knew he would die, the dude just went in anyway. During the last panel, you can even see the doll crying.
I don't understand, someone please enlighten me
her face was blank meaning she didn't have a future *her getting killed right away*
I see, thank you for explaining
