in Chapter 8, how does Nick leave Gatsby?F. Scott Fitzgerald's The Great Gatsby

Nick's departure from Jay Gatsby in Fitzgerald's
The Great Gatsby is that of an epiphany.  For Nick, the unreliable
narrator of the novel, who waivers in his opinions of the main characters, finally
realizes that Gatsby is the only truly genuine one of
all:

"They're
a rotten crowd....You're worth the whole damn bunch put
together."

That Nick is an
unreliable narrator is evident in many parts of the narrative.  For instance, while Nick
has been critical of Jordan Baker's amorality and her having cheated in a tournament,
he, nonetheless, dates her and considers a serious relationship until he senses his loss
of innocence and youth on his thirtieth birthday.  In his association with the
Buchanans, Nick has disdain for Tom's racist views, his careless immorality, and his
cruelty to Myrtle Wilson; yet, he is somewhat impressed with him, saying
wistfully,

"...while we were never intimate, I always had
the impression that he approved of
me."

Early in Fitzgerald's
novel, Nick Carraway seeks to establish himself as a calm observer who is "inclined to
reserve all judgments"; yet, ironically he becomes very involved in the lives of those
he says he merely observes.  In this involvement, Nick comes to the realization that the
only truly genuine character is Gatsby, who remains true to his idealized love of
Daisy.  For this reason, Nick calls out to him, praising him.  But, afterwards, his
comment is ironic:

"I have always been glad that I said that.  It
was the only compliment I ever gave him because I disapproved of him from beginning to
end." 

Having disapproved of
Gatsby "from beginning to end" certainly contradicts Nick's declaration of reserve of
judgment from the early chapter, but it does indicate his epiphany about Gatsby's
genuine--albeit tragic--nature. And, it establishes the unrelaible Nick as actually the
moral center of the novel.
