If I didn't get everything wrong Peter constantly rewrote and rearranged the story during the making of the album until his bandmates urged him to get it finished so the version as it is printed in the album was not so much a final version, rather an umptieth draft of which there was no time left to re-change it.
What I miss most in that story is Rael is kind of a blank slate: who were his parents? How did they raise him, which values or lack thereof coined his actions? Where did he want to get in life? What did he try to avoid? Every writer of a novel or a film asks these questions about their character to give them directions and obstacled that motivate their actions. I can't see any of that in Rael. None of his deeper wishes and fears are ever revealed except for his overboarding sexuality. Even his brother John seems to a projection of himself, he has no lover, no friends, no enemies, no teacher or mentor, nobody who puts him in a certain direction.
