I have a question. When it comes to Pets, do they have any additional dialogue when in the main Vampire Route Quests? Their assistance in fighting is good, but it could add some flavor text.
Yes! There is some flavor text when interacting with certain objects while you have specific Pets with you. There aren't many at the moment, but you can discover some obscure details if you're lucky to find the dialogue. The easiest ones to find are with Edith and Seraphina. Take each of them with you and interact with objects in their respective rooms!
