Yes, yes, and yes to that! I also love seeing how Dark!Claude's (his name starts with an A but like that's all I can grasp lol) paternal instincts for Jeanette seem to be awakening.
I do have a feeling that whatever malicious plan for Claude he's pursuing won't fall through because Jeanette will stand in the way. At that point, which would likely be at the height of the story, I hope he'd already have come to actually care more about Jeanette then and choose her over his agenda. It might equally just as powerful of a moment as Claude finally gaining his memories of Athy back. Again, it goes to show that the family relationships and dynamics are more of the central focus in this manhwa, and the author does it so well.
