I need help with violet's training quest, I got stucked after doing all the other quest, I can't train she, when I try to choose the two options anything happen, just let me leave her, so how can I train her?
When you say you've done other quests, do you mean you finished Jasmine's and Lenyas? Because you need to finish both their story lines completely. Once you do finish them both, you need to go to the kitchen in the morning to progress Violet's story.
