OK, now I have the inclination to offer my take with reference to the comments about Huon's reactions on the ship.
As I'm reading the part about Huon being on MV Southern Explore, it seemed to me that the overreaction probably involves a combination of all the events which Huon, only 17 yrs old, has had to go through. Death of father, dealing with funeral, disposal of parents belongings, being orphaned and no immediate family, encountering a stranger who has interest in and wants a close(er) relationship, taking on a weeks long project covering a wide territory to record singing in multiple churches, final exams. Anyone of any age but especially someone that young might throw a small hissy fit Just Because! Admittedly and overreaction but Not shocking. He wanted to enjoy the excursion but just couldn't get into the spirit. Sad, lonely, the future is uncertain, dealing with a stranger with unknown motives/agenda. So, guys, just think about it.
