Sarah Connor: [voice over]

Watching John with the machine, it was suddenly so clear. The Terminator would never stop. It would never leave him, and it would never hurt him, never shout at him, or get drunk and hit him, or say it was too busy to spend time with him. It would always be there, and it would die to protect him. Of all the would-be fathers who came and went over the years, this thing, this machine, was the only one who measured up. In an insane world, it was the sanest choice.

John Connor:

The future’s not set. There’s no fate but what we make for ourselves.
