For a few weeks, Nick doesn't see Gatsby. Then, one afternoon, Gatsby turns up at his house. A few moments later, Tom Buchanan also shows up unexpectedly with some friends, the Sloanes. Gatsby tells Tom that he knows his wife, and invites Tom and his friends to stay for dinner. They say they can't stay, but invite Gatsby to dinner. Gatsby doesn't realize that the invitation was just to be polite, and accepts.
