Nick arrives at Gatsby's bright and early when he hears him pull in so that he can check on him after his long night of waiting up for Daisy. He had no success in helping Daisy and he stays up late talking with Nick about his past.
The Working Nick
Gatsby tells Nick of how Daisy was the first truly "nice" girl he ever met and how they fell deeply in love. But Gatsby had to lie about his wealth in order to show her that he could support her and get approval from her parents. After he left and she had waited the longest she could, she married Tom.
Wilson: The Vengeful One
Gatsby's Gardener comes into the conversation to explain to Gatsby that he plans to drain the pool to avoid the problem of leaves in the drainage. But Gatsby tells him to wait on draining and invites Nick for a swim. Nick politely declines and leaves, but Gatsby still has his heart set on swimming. (foreshadowing)
The Pool ft. Loss of Life
Nick tries to return to work but is much too distracted to complete any tasks. Jordan gives him a call and he explains that he can't meet her for a date and goes further to think to himself that he is done with that "crowd" altogether. He begins to think back to the events of Myrtle's death.
Nick recalls a conversation that occurred between Wilson and Michaelis wherein Wilson began to suspect that his wife Myrtle had been having an ongoing affair and that whoever was in that yellow car that had hit her, must be the man she was in love with. He sets off on a search of the man who owns the vehicle and ends up at none other than Gatsby's house.
Shots are heard outside Gatsby's manor and Nick comes rushing to the pool and he comes to find Gatsby shot dead in the pool and Wilson shot as well on the ground.
