Yeah, I pretty much agree with that post! When I planned this comic, I still hadn't heard the narrator Chara theory. When I learned about it, I felt like it didn't really change that much about how I saw them in my comic. I considered making some changes to this final part after seeing more and more evidence for Chara's narration (since the narration still continues to the point when Frisk leaves the underground), but I felt like this was still the most powerful way to end it. We can just say that the remains of Chara's spirit held on until they saw Frisk make it outside?
