The killer sends hearts in Valentine boxes to replicate Harry Warden's original warning from twenty years prior. When Warden killed the supervisors, he placed their hearts in Valentine chocolate boxes with a note demanding the town never hold the Valentine's Day dance again. The present-day killer uses the same method to threaten the town and enforce the same prohibition, while also targeting the younger generation who ignored the warning.
