The sixth chapter Great Gatsby response

During this chapter we finally find out that Gatsby was lying about where he came from and much more. Not only this but Nick finally divulges this information now, at chapter six instead of earlier in the book. The reasoning why I think Gatsby lied about where he came from and also about his money is because I believe that Gatsby didn’t think that his own true story was exciting enough, so he wanted to spice it up a bit. But on the topic of why Nick told us this now, I believe that if Nick would of told us earlier, the plot would have been pretty much useless because we would of known that he was lying. Another reason could be that Nick only realized it at this specific moment, that before this he had no clue.
