Continuity mistake: At the end, while Billy chases Kelli, Kelli knocks over a cart of surgery supplies, spilling the material forward. However, a few shots later, Billy is shown picking a scalpel up from the small tin pale, which slid ahead of Kelli. So how could Billy have picked up the scalpel if he was behind Kelli?

Ms. Barbara MacHenry: Didn't I see Clair earlier?
Kelli Presely: Isn't she upstairs writing a card to her sister?
Melissa Kitt: No, I think her sister picked her up earlier. Remember, this is the occasion for Clair and her sister and her mom to bury the hatchet and rediscover each other.
Dana Mathis: I'd like to bury the hatchet with my sister... right in her head.
Trivia: The sorority mom, Andrea Martin, is also one of the girls in the original "Black Christmas". Her name in the original was Phyllis.
Question: Why would Agnes join Billy in his killing spree? She was a victim of him, losing an eye and her parents. She could've joined the sorority girls in stopping him.
Answer: Maybe like him she's also mentally ill, getting it from their mother. Maybe she feels doing this will bring them together.





Answer: Because Agnes is in love with her fatherbrother, and besides, they were invading her home, from her perspective.
