During their trip to Amsterdam, Augustus reveals to Hazel that his cancer has returned, only this time it has spread throughout his entire body, making it obvious that he is going to die. Despite this, Hazel treats Gus as if he is not dying, until one night when he calls her needing her help. Augustus drove himself to a gas station to buy himself cigarettes, but his g-tube became infected and he became very ill. After a trip to the hospital, it is clear that Gus only has a handful of time left. A few days after Hazel reads her eulogy to Augustus, he dies at the hospital. Peter Van Houten attends his funeral and delivers a letter Augustus wrote to him to Hazel. The letter ends with the words "Okay, Hazel Grace?" and the movie ends with Hazel lying on the grass saying "Okay" in return.
