Hi, you asked a bunch of questions so I assume you'd like some answers, I'll try my best.
Not sure if you mean what happened that he's trapped or that his hair changed. I'll assume (oh, I hate that) that you mean how he got there. That's not really relevant to the question of what his reaction would be about his hair changing. Although I understand how you would want to know.
This isn't a question you ask but I do have an answer. Think of this as a word association game. I give you a word and you give me the first thing that pops into your head. I have several different reactions that I could have gone with on my own but asking a few people for their ideas broadened my base.
Umm, again, not a question but I'm not sure how to answer it. Sorry.
But that does lead into your:
Yup, exactly what I wanted, to get others emotional responses.
I do say he is with a friend, so I guess I thought the implication was that the friend was there.
In this case he did but I didn't consider the friend's reaction relevant, I was only interested in the boy's reaction.
Again, not relevant to me for the response.
Again, I did say he was with a friend.
Hope this clears up your questions.
I really was hoping for that quick word associations type visceral reaction. A little like when you're give a one word writing prompt and you have to create a thousand word fiction story about... elephant.
Thanks for your comments. I've learned quite a bit with today's questions and have gotten some great takes.
