I believe the best answer for this question is "entropy." Entropy is a scientific term referring to thermodynamics. It measures both the order and the disorder of a system. Order, or disorder, are both defined by how close the system is to equilibrium. Hope this helps. Also, keep in mind to ask questions in the proper category - this would be most suited to science, rather than English. Thanks.
For this analysis I will deal with the element of characterization in the short story "The Instrument" by Canadian writer Wayde Compton. It tells the story of twin brothers Albert and Donald. They used to be siamese, conjoined at the back of their heads until they underwent surgery as children to separate them.
The conflict in the story arises when one of them wants to record a documentary about their father, a former musician that seems to have become mentally ill after years of drug use. The person financing the documentary is the same millionaire that paid for the surgery decades before. While Donald wants to record the documentary and interview his father, Albert will try to stop it because he thinks their father is crazy and he will embarrass himself.
The conflict is framed through the separation between the two brothers, both physical through the surgery they underwent and the resultant emotional separation. At one point, Donald sees Albert for the first time in a while, "Donald runs a hand over his own scalp, seems to catch himself doing it, puts his palm down flat on the white table". This quotation points out that the first thing that comes to mind when they see each other is how they were joined or connected, and we may hint some longing for reconnection, even if it is through reflex actions like touching the scar in the scalp.
Answer:
The 'surpise' in Zaroffs bedroom was a suprise attack from Rainsford. For him, the most dangerous of hunts is not over yet as he is cornered in Zaroff's room (hence the allusion to baying) and has no choice but to fight.
