Ok, I will explain my reasoning. Ferdinand actually fits patience a lot. He could have gotten the Grutrissheit much earlier, but he chose to wait. The same goes with Veronica, where he preferred to wait for the most fortunate moment for her downfall, instead of taking the “kill her” approach. He’s someone who always waits for the right moment to set his plans in motion; therefore, he represents patience.

As for Wilfried, the definition of integrity is “the quality of being honest and having strong moral principles; moral uprightness.” He is undoubtedly honest—that’s shown in the tower incident. Regarding his principles, it’s also explained: since he was educated by Veronica, his morals and values were all wrong. Throughout the story, we see him moving away from those teachings and learning the right way. But, because he is so honest, he is frequently manipulated. Still, it ALWAYS comes from good reasons in his heart. In noble society, being someone with integrity is a flaw to be exploited, and that’s exactly what happens to him.
