This allusion gives a sense of the ending in the very first sentence, almost as if it were predetermined.
Concrete is revisited in the hospital scene, where the observer ‘guides’ the human by inserting doubts into their mind. The observer includes criticism from Dogma and reflects Screwtape’s views on the church:

When he goes inside, he sees the local grocer with rather in oily expression on his face bustling up to offer him one shiny little book containing a liturgy which neither of them understands, and one shabby little book containing corrupt texts of a number of religious lyrics, mostly bad, and in very small print. When he gets to his pew and looks round him he sees just that selection of his neighbours whom he has hitherto
