Listening to Dee3, Ace was certain her research days weren't behind her—she simply hadn't found anything interesting enough to reignite her passion. For example, a curse slave who could listen to the world's mysteries. Realizing this, he saw the odds of convincing Dee3 to mentor his Toy Summons shift in his favor.
Meanwhile, Janice and Delores nodded in understanding, having learned something new about the mysterious Curse Caster profession. However, had Elinor not been busy, she would have pointed out a flaw in Dee3's explanation. That her Dream Invader/Teacher had begun instructing her in the ways of Curse Casters even before she underwent the curse core awakening ceremony. Meaning her Dream Invader/Teacher knew she had the potential to become a curse caster even before she condensed her curse core.
