Why did she ask this question? Rolin was filled with doubts, mulling over the question herself, furrowing her brows, realizing that the matter wasn't as simple as it seemed.
The reason for her realization was simple—because the question was too simple! So simple it shouldn't be raised in the first place. Moreover, Violet, being someone so intelligent, wouldn't engage in such meaningless acts.
Thus, behind a simple question, there must be something far more profound, even unpredictable.
This was the conclusion Rolin arrived at, not knowing that by the time she realized this, she had already fallen into Violet's trap.
Having the opponent fall into a cognitive trap through a simple question and then start rationally thinking, this was Violet's clever strategy.
