Thank you and Dani so much for your very kind remarks - they are much appreciated.
That's a really interesting question as to what happens to Marcus after the end of 'I Believe in Peter Pan' and one I must admit that I hadn't thought about.
I think that maybe his twin brother, Peter, is always with him in one way or another. My Dad was a twin and he and his brother were inseparable pretty well all through their lives. When my Dad died (natural causes in old age) his twin brother (now very elderly himself and surviving my Dad by two years) refused to ever believe that his twin was dead and literally would say 'I can see him standing there by you'.
He said that every time that we tried to tell him that my Dad had passed on (that, I promise you, is the absolute truth).
Whether Marcus ever meets JMB again I don't know, I guess not. I have the feeling that JMB, with all his magic and enchantment, came to Marcus and brought George, Jack, Peter, Michael and Nico to Marcus in the hour of Marcus' greatest need. There is no doubt that Marcus (and his family) were very much on a downward spiral before he left Bristol to come to his Aunt Mary and Stanway and JMB.
I think the mingling of Past and Present was also part of healing Marcus' great loss of his much-loved twin brother and I believe Stanway helped to heal Marcus just as it had once helped to heal JMB in his great loss(es).
Just some thoughts.
