Terminator: The Sarah Connor Chronicles2008

John Connor:
You know, I've been running from the machines my whole life. They tried to kill my mom before I was even born. When I was twelve, they sent one after me. I was a kid. I was stupid. I didn't know what it was all about. Both times, future me sent someone back, to stop them. The first time it was a soldier. His name was Kyle Reese, and he died saving my mother's life. Second time it was a machine. I used to wonder why I did that - why I took that chance. I don't wonder anymore. Human beings can't be replaced. They can't be rebuilt. They die and they never come back.
