:( when he gets older he gets a prosthetic arm

His parents murdered each other, he saw his adoptive father get his head chomped off, he has a cursed doll with him Eta ripped the arm of the doll of causing 14 year old pepsi to lose his arm, and Eta also smashed pepsi's head with a hammer

he was 14 when his parents killed each other. all of that happened in less than a year

yes

he also has a scar over his eye because his adoptive mother wanted to know if he was lying or not
