Awesome story! I really like the wisdom the kid has accumulated in being dead longer than the main guy. The main guy is looking down on him like he is just some pipsqueak that knows nothing and would just be an annoyance. Turns out the kid is actually a wise young ghost with knowledge to share. Just goes to show you can not judge a book by its cover.
The fact that they are both dead is really sad. but the fact that they have found each other offers a little hope. I wonder how old the child was, or the main character.
I would suggest tucking the prompt into a drop note they are even less distracting than the route you took. I feel like they help you clean up the piece a bit. All in all not much to criticise.
