Yeah, it is as hard to understand as it is to watch.

* AnimalMotif: "The Buffalo." A traumatized Brenda tells Grissom "the buffalo" went to her room and nothing else. Grissom goes through the family's effects and finds an amulet on a chain which belonged to Mr. Collins. He cleans the blood off the amulet and discovers a buffalo.
