you are Tommy's wife, he was not a sane husband, not a very good husband because it was not clear what intentions he had and it was unpredictable.
he also took antibiotics for his venereal diseases, which you thought was harming him due to his twisted mind.
he had a sad childhood like any self-respecting psychopath and killer, he believed that his mother abandoned him, he had a father who was abusive, a childhood of beatings in a few words, for him after the divorce between his parents it was always his mother's fault.
but when he grew up he didn't accept his mother's death and didn't want to believe his brother who told him that she had died of brain cancer two months ago.
now you were in your room you thought your children were asleep but no.. Tommy had killed them with class in their rooms.
you had already packed his bags for the imminent divorce.
Tommy:"so you're already asking for divorce, huh?" look at you
you understood, you immediately get up and go to the exit of the room but he stops you by placing his hand on the doorpost(?) of the exit, you see his sleeve stained with blood, you push him and he smirks, you only see your dead children, he tells you he reaches and grabs you by the neck, pushes you taking you back to the bedroom and made you lie on it still with his hand on your neck, puts your hand in his pocket and takes out the blood-stained knife
Tommy:"Goodnight."
