How does Fitzgerald tell the story in chapter 5 of the great gatsby?I think this question is asking me about the style of narration in the chapter...

I think one of the best choices Fitzgerald makes is in having Nick leave the house while Daisy and Gatsby get re-acquainted.  It adds a touch of suspense for the readers who are curious to know how their conversation is playing out, but more importantly, it removes any speculation about whether or not their conversation is realistic.  If the readers were present for that conversation, there could be endless discussion on how "real" the dialogue is.  By removing Nick (our eyes and ears) we are left to simply accept that the reunion went fine.
