The Fault in Our Stars Chapter 20 Summary

Augustus calls Hazel on his last good day and asks her if she'll prepare a eulogy for him and come to the Literal Heart of Jesus that night.
Hazel's parents tell her that she can't spend all her time with Augustus, but she counters that he has a limited amount of time left.
She gets into a fight with them, finally leaving even though they don't want her to.
When they protest, she tells them that Augustus will die any day now, and that totally shuts them up.
She drives over to the Literal Heart of Jesus and sees Augustus in a wheelchair.
He says he wanted to arrange a prefuneral for himself.
Isaac gives a eulogy about how Augustus is an arrogant bastard, and then starts to cry.
Hazel also gets up and gives her eulogy, and of course, she cries, too.
Her eulogy is about infinities and how she's glad that she and Augustus got to have their own infinities.
