Not really a plot hole, but a bit of an "oh no."
Early into my run of posting my comic on Tapas, I got a review from @darthmongoose about my webcomic Hollow, which was mostly very positive, but she mentioned (and I'm paraphrasing here), "Man, I hope Levi's whole thing isn't just that he's in love with Skyler and they kiss and make up." And also, "Levi seems all cool swooping in with his magic coat and saving the day, but it's only because he was right. If he was just wandering around in a magic coat for the last six years with no magic around, then he looks like a doof."
And I was like...
Because that's exactly what I had written in my original draft of the comic. And she was entirely right in pointing those things out, they were basic character and story flaws that I hadn't noticed myself. Levi needed better personal motivations, and I needed to balance out Skyler's perspective of "the magic is gone forever, I don't even carry the Amulets around anymore, better get a retail job and go to college" with Levi's perspective of "I still keep a spellproof coat in the trunk of my car when I go grocery shopping because the magic could come back at any moment, I can't move on with my life in any other way."
As a result, I rewrote a huge section of the story, which made it so much better, made Levi's character a lot more nuanced and with actual character depth and motivations beyond just "I have a crush on a guy I haven't seen for six years" (though he still kind of thinks that's his motivation), and honestly kind of informed an entire new moral meaning to the story. It helped literally every aspect of the story in ways I wouldn't have considered myself, because I was leaning a bit too hard on the nostalgia tropes and not leaning hard enough on the "reality" side of the tropes, which is the whole point of my story.
So, it was an Oh No. But it turned out to be something really amazing for my story, and I'm very glad it happened.
