In a fit of rage, the narrator admits to killing both and burying them under Jacob's sycamore. This revelation suggests that they are capable of extreme violence and have committed heinous acts. The narrator then addresses their mother, acknowledging her perception of them as "psycho." They mention unintentionally breaking her cup, further indicating their unpredictable behavior.
