Don't get me wrong, I think I know what you are getting at. 'David' first made his appearance photographically in front of the red curtain. He bears a resemblance to the 'David' identified by Mark in the group photograph. However, as no one has ever been able to confirm the birth or death of 'David' and the colour photo has signs of tampering, heaven only knows who that young man really is.
And now you have to decide whether these two look enough alike to be mistaken for each other in the street in Nairobi like it says happened in 'Dreams' or not.
What about these pics, who are those two grade school age boys?
