?? what happened to his mom and his sister in the flashback i’m lost

The mom want to triple suicide. or double? not sure if she wants to kill sister too but she was about to poison her son and herself. ig she only suicide alone cuz they ran away. these things weirdly common in a broken single parent household

yea i figured out the sister was poisoned cause she ate the cake but i don’t remember the mom eating it or maybe i missed it

She probably ate it after they left the house and the kids found out after the police went to their place

ohhhh
