Yes! I'm so happy you did this.
My theory is the Witch knows what's going to happen next like she some kind of connection to the Goddess or Demon perhaps both?
I think she also has been following Aria and Caelum too someone she says about Aria is strange.
Talking to certain people seems to suggest she might not be entirely from this land and maybe not even from the village either because we never really heard what the Goddess or Demon told her when she was chosen unlike Caelum so that is very mysterious, I don't think she is being honest with him about what she was told. Her name seems off as well I thought maybe Caelum gave her that name as she didn't have one when they met.
Perhaps she was singing one day, and he gave her that name after hearing her voice?
As for scenes I think we should start to discover more about our destiny as we head deeper into the cave with a new party member along the way? (Please be a woman.)
Just some of my ideas and thoughts for now I don't want to overwhelm you (I have so many notes and wants.)
Thanks for listening.
