Answer:
He would use third person omniscient point of view.
Third person POV is a narrator that is not a character. Third person limited POV only knows what one character is thinking and feeling. 3rd person omniscient knows what every character is thinking and feeling.
What I was taught was to think of 3rd person omnicient as God; sees and hears everything, and know what they're thinking/feeling.
I hope this helps :)
