Well, I would not use the word "discusses". The protagonists visit all these stories, and discuss them inasmuch as they are IN each story. Also, they only enter stories all four of them (or maybe at least three out of four?) really like. Which prompts Zeb to ask worriedly at one point "Does anyone here besides me like H.P.Lovecraft??" (Because being stuck in the universe of Necronomicon would have been a Very Bad Thing.)
