Just a thought. And I could be wrong.
I really don’t understand your point, you’ve discovered the one and only image there is of the boy whose image Malik uses to promote his fund raising activities - a boy who appears to be somewhat polynesian and has one dark arm, and no one has been able to find him. The rest of the story about ‘David’ comes out of ‘Dreams’ and you can make of it what you want. It carries on to desribe how zero and Auma, one day, in the street, met a man who mistook zero for ‘David’ because they looked so much alike...and sadly, they had to explain to the man that no, zero wasn’t ‘David’ he had died...
Wake up and smell the coffee. You’re being played.
