In Chapter 5, Daisy and Gatsby meet again for the first time in years. At first, Gatsby wants to back out of the reunion. He has built up this moment in his mind so much that he is now getting cold feet. Nick tells him that both he and Daisy are just as embarrassed. They finally meet and Nick leaves them. He comes back to find Gatsby and Daisy sitting on the couch "and every vestige of embarrassment was gone." It is evident that Daisy has been crying and Gatsby looks completely different. Nick adds that it is not the result of words or even a gesture. Gatsby looks as if "a new well-being radiated from him." It stops raining and Gatsby smiles "like an ecstatic patron of recurrent light." Gatsby is clearly full of joy at finally being reunited with Daisy. Her tears indicate she is overcome with his passion and the feelings she used to have for him. And she still does have some feelings for him.
They go to Gatsby's house and Nick notices that Gatsby has not stopped looking at Daisy. Gatsby is enchanted and obsessed with her. Gatsby shows off his house and shirts which causes Daisy to cry. She is still overwhelmed to see him again and is probably overcome with how Gatsby has made a fortune for himself. Recall that lack of money and the war were the two things that kept Gatsby from marrying her years ago.
Later, Nick sees a look of "bewilderment" in Gatsby's face. Nick supposes that despite his joy, Gatsby must feel some sense of doubt because Daisy could not possibly live up to his idealized vision of her. But then Daisy says something to him and Gatsby is enchanted once again. Nick adds that they "looked remotely" at him and the two of them were now "possessed by intense life," indicating that they are totally enchanted by each other.
