Would Chapters 3 and 4 have benefited from having other Lightners like Toriel, Undyne, Catti or Jockington join us in the Dark World party? It's weird that we got Noelle and Berdly for Chapter 2 only and nothing like that for 3 (besides Toriel and Undyne doing nothing) and 4. I simultaneously think it would have been fun but I also think that it would make the story too convoluted, with so many people knowing about the Dark Worlds and all.
