@ParagonNight that's a memory (?) of the former Raeliana and how it went in the story's novel. The man in that section is Francis, the poisoner evil fiancée that our Rae dealt with in the first arc. In the novel, Raeliana married him, he poisoned her, and her death became the catalyst for the novel Beatrice's story.
It's a strange transition because we weren't shown the context of why this scene appears. Is this a memory of the former Raeliana who may have now become Beatrice? How does she have a memory of something that didn't happen on this timeline? We don't know...yet.
