In chapter one how does Nick react to jordan?
Initially, Nick feels like an intruder, disturbing the rest and quiet of the lovely lady reclining on the divan. "Almost any exhibition of complete self-sufficiency draws a stunned tribute from me."
As he observes Miss Baker attempting to eavesdrop on Daisy and Tom, in another room, Nick becomes aware that she seems to know more about Tom and Daisy than he does - not all of it flattering. Jordan hints that "Tom's got some woman in New York" and pumps Nick for information about his neighbor, the mysterious Gatsby.
Once Nick realizes who Jordan Baker is and why he had felt like he should have recognized her earlier (I had heard some story of her too, a critical, unpleasant story, but what it was I had forgotten long ago), Nick isn't sure he appreciates Daisy's decision to act as matchmaker for he and Jordan. Upon his departure, Nick echoes Jordan's comment as she had gone upstairs for the evening that he "had heard nothing at all."
