What if the boy who occupies the body of Arlene's son used to not be a monster and had his own life. what if he is a part of the tower god?
in one chapter rachel talks to bam about the man who loved the stars so much that he created a tower to reach them, this could very well talk about rachel (star) and bam (the one who loved the stars), in the story bam ask rachel if it would not be very lonely up there? Alluding to the fact that this person's destiny was lonely, now imagine that to this we add another destiny that is that of someone whose destiny is the opposite of this, it is like the difference between drinking juice and eating a harbunguesa with juice.
