The setting contributes to the story a lot. It is dark and rainy making them not able to see the island. It is night when Rainford falls off of the boat. The mood is dreadful and mysteries.
The main characters are Rainford and Whitney. Whitney is more gaolable, he was quicker to believe that the island "myth" was real. Rainford is motivated and more of a leader. He looks out for himself but also cares about others around him. This is shown by how he treats others around him.
Rainford's emotions are scared at the beginning when he falls off the boat. They soon turn into hope and excitement when he comes across General Zaroff's house/cabin.
The first conflict that occurs is when Rainford falls off of the boat and has to find the island. It is hard to see because of how dark it is therefore he has no other choice but to guess the location of the island. This is an internal conflict because he has to decide what choice he makes.
The theme of the story is a guy and his friend are out traveling over sea. One night after coming across a strange island Rainford falls off of the boat. The story goes along with Rainford while he try's to figure out a way to get through obstacles.
The irony of this story is complicated for me. I don't see any irony involved. I think irony can contribute that a story a lot and is very important but I don't see any used here.
