The wedding
The final scene in the book is of the wedding between Maxon and America, but it is so much more. It shows a picture of a united front, a new and strong country, without the caste system. It is new, different and stronger than ever before. The wedding is without Maxon's parents, which is important, as they represent the old Illéa.
Celeste's new beginning
In the early stages of the book, America finds Celeste crying. She then proceeds to tell America her secrets, of how she is afraid that her career as a model will end when she gets older. Celeste apologizes for all the times she has been horrible to America, and gains America's forgiveness. This not only redeemed Celeste, but America as well, as she no longer had any enemies ( except the king) in court.
The Convicting
The Convicting is an event in which the Elites must condemn criminals to jail. The king gives a criminal to America who is to be sentenced for life, because he tried stealing clothes for his children. The king wanted to make America seem unfaithful and merciless to the people by doing this. America makes a plan. Instead of condemning the criminal, she pays for his debts, releasing him from jail.
Maxon and the king
After the Convicting, the King tries forcing Maxon to eliminate America from the Selection. He stands up against the king, protecting America whist proclaiming his love for her. This is one of the most touching scenes in the book, as it shows how much the Maxon truly loves America.
