There are several parallels in this episode to the classic novel Moby-Dick. Revenge and its consequences are a major part of the book and episode. In this case, Sabretooth represents Captain Ahab as he seeks revenge at any cost against one figure he cannot defeat, eventually leading to his own doom. Wolverine is the "white whale." Kiyoek would be Ishmael who is swept up in this revenge and is ultimately spared from death by abandoning the quest for revenge. The book deals with whaling and the episode features people known for whaling as well as two characters going out on a boat with a spear similar to the whalers of the book.
