Hogarth Hughes: I know you feel bad about the deer, but it's not your fault. Things die. That's part of life. It's bad to kill, but it's not bad to die.
The Iron Giant: You die?
Hogarth Hughes: Well, yes, someday.
The Iron Giant: I die?
Hogarth Hughes: I don't know. You're made of metal, but you have feelings, and you think about things, and that means you have a soul. And souls don't die.
The Iron Giant: Soul?
Hogarth Hughes: Mom says it's something inside of all good things, and that it goes on forever and ever.
[Hogarth leaves. The Iron Giant lays back to look at the stars]
The Iron Giant: Souls don't die.
