After defeating the Faceless Blade and her committing seppuku, during the unnamed sequence where you experiment with the Ring of Fate with Calise, the dialogue option with Calise at her home about the assassin does not change to reflect the assassin is now dead.
Instead, the same dialogue is used, where Calise discusses that it may be possible for the Faceless Blade to infiltrate the city, in spite of her now being dead.
