I understand things have to be set up. This chapter wasn't the best, though. How did Harry know he could demand things? And how did he know what was possible? Anyway, interesting idea, no matter how it came about. I'm looking forward to see what you do with it.

OK, Harry didn't 'know' per se, but he was being given a choice. Either stay with his parents and loved ones, or go back and try to fix the problem. He made no demands. He simply told Merlin what he would need to get the job done. His conditions were simply necessary to the situation. As for how he knew what was possible...he was dead. every movie I have ever seen, of people in the afterlife, included something about 'dreams made reality'.
