While at dinner, Kramer asks a Miss America contestant what she would do to make the world a better place. She says that she would try to end world hunger.

Mr. Z is trying to take all of the zeros away with him. Jackie, Matt, Inez, and Digit discover that zero has meaning just like any other number. They use real-world examples, such as telling time or taking an elevator to the 10th floor, to show what will not be possible without zero.

Louise's daughter asks her for the technical term of a deal in which both sides can win, and Louise does not recall the term at the time. Louise's team has a discussion about their findings on alien data, and they realize that there are 12 total groups, each with a different set of data. They will need to share data with the other groups in order to obtain the full set of data, which they determine is a non-zero-sum game. Louise then recalls the technical term for a win-win situation and relays it to her daughter.
