After helping Healer Fama, a group of Asassins led by Lucile will appear. With her is also Magic Swordsman. However, throughout this cutscene, only Lucile's dialogue box appears.
Officer Heim's dialogues did not appear in the first part in her conversation with Lucile, as you can see inside the chatbox at the bottom. Those are all Lucille's dialogues only.
Later on, when Lucile talks to Magic Swordsman (Thanatos), the swordsman dialogue also did not appear.
Even later, at the top of the tower ([email protected]), it looks like the Magic Swordsman is missing a line because Lucile seems to be responding to him.

Corrected NPC name to Heim, not Fama
