 The film ends with Mini giving a valedictorian speech, even though she is a C student; the school gave her straight A's out of sympathy for her mother's death.She offers advice to the graduating class about how to live a good life, that perversely alludes to her crimes without making her look too suspicious.The detective is present at the speech, clearly still suspicious of Mini, but knowing that he will probably never be able to prove that she was guilty of murdering her mother.
