- I've seen it before, and I'm sorry.

- I did what I did because, I had to.

- When the Matrix was first built, there was a man born inside who had the ability to change whatever he wanted to remake the Matrix as he saw fit.

- It was he who freed the first of us... taught us the truth.

- As long as the Matrix exists the human race will never be free.

- After he died, the Oracle prophesied his return and that his coming would hail the destruction of the Matrix.

- End the war. Bring freedom to our people.

- That is why there are those of us who has spent our entire lives searching the Matrix looking for him.

- I did what I did because I believe that search is over.
