The film leaves ambiguous whether Peter (as a real person) or KK himself committed the string of murders. KK is arrested for the killings, with police suspecting Peter as the perpetrator. The line between the two identities remains murky throughout, challenging viewers to question whether Peter is a separate entity or a manifestation of KK's own violent impulses.

The film deliberately leaves Peter's existence uncertain, was he a real person who committed murders, or a fabricated alter ego born from KK's mangled psyche? The ending provides no definitive answer, leaving audiences to question whether the violent acts were committed by a separate entity or by KK himself while dissociated.

Foreshadowing: The narrative hinges on this central ambiguity throughout.
