Carol:  Although she felt a little guilty about it, Carol had eavesdropped on their meetings more than once or twice. Each time, she had been prepared to leap out and cut Wilhelm down if there had been any trouble, but she had always been disappointed. Or, well, disappointment was not the right word. After all, she saw Theresia smile and laugh among her flowers. It had been so long since Carol had seen a smile or heard laughter from Theresia. In the five years during which they had been master and servant, Theresia had spent only the first six months in anything like happiness. After that, the Demi-human War had erupted, Theresia had attempted her first battle, her heart had been broken, and her smile had disappeared. But here, Carol saw the true Theresia van Astrea. And if Theresia was willing to acknowledge and trust this boy, then Carol begrudgingly admitted that she would do so, too. It was at this time that Carol was also growing closer to Wilhelm’s comrade Grimm. He, too, thought very highly of Wilhelm, and her impression of the Sword Devil began to change. Ultimately, Wilhelm achieved great things in battle and was even granted a promotion to knighthood. He took the place that had once been reserved for the Sword Saint, Theresia, and now it was the Sword Devil people looked to as the one who would bring an end to the Demi-human War. Carol admitted with admiration that Theresia’s judgment had been right. After that, she saw a change in how Wilhelm thought and acted. The barely restrained, bestial intensity began to subside. He showed consideration for those around him and dedicated himself to living up to the hopes people had for him. He was attempting to be the very picture of knighthood. The change was extraordinary. But everyone believed it, and even Carol found herself thinking more kindly of him. Though they still argued, she had no choice but to acknowledge who he was.

Carol:  There was no need to describe the meetings between Wilhelm and Theresia. She waited for him by the field of flowers, greeted him with gentle visage and voice. Anyone in the world could have guessed what she felt for the Sword Devil. There was no question that the two of them cared for each other and that their hearts had forged a connection. That pleased Carol, and she genuinely wished them happiness. It would be untrue to say she felt no jealousy toward Wilhelm, who had been the one who was able to tease out the true Theresia. This was part of the reason she would always continue to needle him publicly. But all the same, if Theresia was happy, that was enough for Carol. Theresia had been hurt more than enough already.
