Badeni is an a$$hole, but man is he a interesting well written character. As Jolenta mentioned regarding reading & writing last week they are special skills in this time that they live in. To read is to understand, but writing is how you leave your mark. I get why he questions why Oczy would want to write because what they have been doing is better to be kept underwraps. Still I do feel like Badeni somewhere deep down is impressed that Oczy would be interested to learning to read & write.
We getting the perspective of Grabowski and him asking for how rainbows are made and then him asking how to explain it to the kids is hilarious. I can imagine working with Badeni is not the most easiest thing in the world. Though before Piast died he dropped what he was writing down. It seems like Grabowski found it and I am intrigued where this takes us next.
So the reason for the scar Badeni has is because of a fight he had with his friend regarding research. In which he killed them. This showcases it even more what Badeni thinks of his research and why his trust with others is at an all time low. Though it is interesting that Badeni says the heliocentrism theory is done, but clearly he is still planning and making moves.
Inquistors aiming to save the heritics? Well that is interesting. They will be training with our old body Nowak.
