Fantasy Island Prompt

Why did they have three story lines in one episode instead of just having three separate ones? I'm confused about how Paul Henley got back from the desert where he had made it through the last phase of the hunting game back to where he arrived off of the airplane.

In "The Most Dangerous Game" Rainsford did not want to be hunted. General Zaroff did not own the island and had a large sidekick Ivan. Rainsford stumbled upon General Zaroff's house. On the episode of Fantasy Island Paul Henley wanted to be hunted. Mr. Roarke own the island and had a small sidekick Tattoo. Paul Henley wanted to go to the island to live out his fantasy.

In "The Most Dangerous Game" both the men were on an island. Both of the men got hunted. Both of the men were very skilled hunters.
