All right, Morosis, let's go! Top down on the lovely Nathan…
Oh! He's just fully deceased! Didn't see that one coming, I won't lie to you. But cool! Wacky. Love to see ghost representation in the media.
ANYway. Nature. You haven't given me a lot to worry about here. Everything seems to spiral smoothly from central traits of loneliness and 'good-listener-ness' (you'd think I know a word for that at this point). There's one conflict that jumps out to me right away. Now, a character can absolutely be mischievous and caring at the same time–that makes perfect sense. But what doesn't make sense is that he'll meddle in people's lives to the point where they're paranoid. That's taking it too far for a guy who seems to care about his friends. Even if he's messing with people he doesn't know, Nathan has been described as the supreme listener with the open-mindedness of a god. You'd think that kind of empathy breeds a sense of consideration for everyone, save a few particularly bad eggs. What's the line for him? At what point will he move from messing around with someone to causing that person to live in fear?
Also, what's he like when he gets caught going a little too far? Now I'm no expert, but if I caught my ghost friend spying on me, I would get angry, no matter how well-intentioned he is. Has he ever made a friend angry? How does he get their attention to apologize, reconcile, etc.? It's not really necessary that you think this one through unless it comes up in your story, but I just thought it would be interesting to consider.
For politics, you tell me a lot about influences on his views, but not what those views are. If I were to hazard a guess, I'd assume he'd be close to center, having observed so many different people. But whatever you choose, it's essential that you choose a view for Nathan, I believe. It makes sense that someone who observed so many people would have had time to organize their views. Same thing with religion, I would say, although that one is a bit less concrete. After all, what religion believes ghosts are around and can possess the living? (Actually, probably several, not going to lie).
Backstory seems solid overall. There are just a couple key points that I feel need further explanation. One, the mugging. How late were these people out? They were on a main road, likely well-lit and well-traveled, and yet they were easily attacked and robbed. I genuinely can't think of many times of night, save in the early hours of morning (and I'm talking like 3-5 here) when there would be NO ONE on a main street. It's a tiny detail, but it confuses the whole event. Two, um, how did Nathan, you know, REACT to being a ghost? For some reason, there are no details about his reaction. Was he horrified? Shocked? Did he initially find it cool, just to realize that it wasn't a temporary thing and he couldn't revive his body? I know you probably have that fully fleshed out in your head, so I won't go off on too much of a tangent. I'm just making sure you have that reaction solid, because I think it's key to his character progression past that point.
Okay!! I think that's all I have for you. I had to nit-pick hard to find anything to say about Nathan. Really quite a well-done character here! But in any case, I hope what I've said helps you in some small way. :DD
Thank you so much! I'm so glad I was able to catch you off guard with Nathan as a character! As for the critiques, I will tend to them immediately as they are all very well-founded. I completely agree with all your points. You're a great critiquer, by the way, your points are very detailed and yet you display them in a way that isn't rude or submissive. Thank you and great job!
