Yeah, watching Maughlin the Armourer and Lenigrast the Blacksmith, forget where they came from, not recognize their family, forget what it is that drives them. And Lucatiel as she understands that her curse is starting to properly take hold so she makes sure to say goodbye while she still has her wits about her. Makes you fear hollowing that much more, I feel.

It really seems like they take a lot of "inspiration" from dementia, and that is probably why it's so terrifying.
