Sarah: Watching John with the machine, it was suddenly so clear.
The Terminator would never stop. It would never leave him. It would always
be there. And it would never hurt him, never shout at him or get drunk
and hit him, or say it couldn't spend time with him because it was too
busy. 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.
