The Angel understood that if Neo managed to save the world, the present would change.
A lush world filled with life would appear instead of a world filled with maggots and decay.
Vibrant forests, clear skies, and rivers singing with life—the opposite of the rotting, gray husk they stood upon.
What would happen to Professor Daniel, Neo, and the Angel?
Professor Daniel would return to the future, from where he had come.
Since it was a paradox loop, nothing would change for him.
However, Neo and the Angel had nowhere to go.
They were 'errors.'
They existed in the destroyed world, not the world filled with life.
If Neo succeeded in saving the past, the present would change.
The destroyed world would vanish, along with Neo and the Angel, and be replaced by a world filled with life.
'Stop it, you self-sacrificing asshole—'
"You… don't need to worry," Neo suddenly spoke.
