We have to recall that the miracle of reading and writing is what Jolenta pressed on. No surprise that she would have the conviction to sacrifice herself so that book gets published. Which with Draka even more get published. At this point, Jolenta is passing the torch to Draka we could say. In many ways, she saw herself in Draka a young girl who deserved a chance.
Though her main point on how young people are the protagonists in history was a great mention. They can take what has happened before change the future. Even more so, history is God's will. We can take what happened previous and learn from it to shape the future. It even goes back to the quote in this series "A wrong answer is not a meaningless one." We can use what has happened and learn from it. Jolenta is one example of that because her life was not easy. For Jolenta her father being an inquisitor is an import aspect. She knows it will be tough to face him, but it feels like she is prepared.
Meanwhile, Nowak doesn't realize his daughter has finally died. Much like he never realized she was helping out Oczy and Badeni. It is cruel Nowak will never learn the truth. Though could you say he was sparred? What would he have done if he learned his daughter loved Heliocentrism?
As for the other two key members. Schmitt is one that leaves me uncomfortable. He is a believer in things that are natural by God. Though he hates technology/things that are man made, but is fine with using them to fight the very same. It makes him a hypocrite. Draka's mention how human technology can finish what nature can not. It is stuff that is unnatural. Which makes its use excellent. Of course, over reliant on this technology is still an issue. Meanwhile, Lewandlowski seems to be a good dude all things considered. Though his point is very true is that it is humans that punishes said heretics. After all torturing them and burning them to their deaths. Those aren't things done by God.
I am really curious where happens next since the knights stopped them.
