No because in the end If you read the last chapter in the book (chapter 9) during the fall (October), after tom basically confesses that he told George Wilson that it was gatsbys car that ran over myrtle and says that he had it coming because he ran over myrtle and nick says: "there was nothing I could say, except the one unutterable fact that it wasn't true." So daisy hadn't told him and this was him months later still thinking that Gatsby did it and nick couldn't say it either.
