Important: if the first part of the quest isn't completed by the time The Isle of Mists is started, it will fail.
After fencing with Rosa during the quest Broken Flowers, return to the var Attre villa and say "Due to meet Rosa" to the guard captain at the door. He will inform you that Rosa went to the Temple Bridge and asked you to join her there, earning 10 .
Upon meeting with Rosa, she'll show disdain at having a guard accompanying her, but manages to send him off and asks you to follow her. Answer however you like, then follow a short distance to the center of the bridge where she'll challenge you to a duel. Regardless of who wins the duel, Rosa will run off after tricking Geralt into looking the other way, earning 25 .
Use your Witcher Senses to discover her footprints and Geralt will note she headed in the direction of the Seven Cats Inn. Follow them there to find Rosa being harassed by two drunks who realize she's a Nilfgaardian and not too happy about it. You can then do the following:
- use Axii (requires Delusion level 1, earns 30 )
- pay them 50 to leave (earns 5 )
- fight and kill them
- Geralt had learned that Rosa var Attre was a passionate devotee of the art of swordplay. The fencing lesson Geralt had given her while searching for yours truly had thrilled her to the core - and left her asking the witcher if they could meet again for a repeat. Geralt had plenty of experience teaching young women with fiery personalities how to swing swords and so agreed.
- Once they were done with their lesson Geralt was supposed to escort the young lady home. Rosa, however, was clearly still in the mood for some recreation and gave him the slip during a moment of inattention. The witcher knew he needed to find her - or land himself in a heap of trouble.
- Rosa found out for herself that not all residents of Novigrad respect diplomatic immunity. The witcher saved her from a tight spot - but also discovered a dark side to her character. It was clear to them both that there would be no third fencing lesson.
- Go to the var Attre residence tomorrow to give Rosa fencing lessons.
- Tell the guard captain about the fencing lessons.
- Meet with Rosa.
- Follow Rosa.
- Defeat Rosa.
- Use your Witcher Senses to find Rosa.
