More everything more all at once.
So morphs are capable of mimicking humans naturally, it's just it would take longer and they wouldn't output a desirable amount of soot if they did and so the fragment of favor is used to amp that up.
If both Albert and Catherine escaped, I'm kinda curious as to what the deal with the Great Grandfather is. If I had to guess I'd say he's the original morph that was given as a gift, but as for what the hell he mimicked to look like that (he's literally over 10 feet tall and no part of his body has been seen with a defined shape) I have no idea. I've also had the theory that he's literally just a figurehead, we've heard his voice but if I recall the only time we even saw him move is when he raised his hand at the end of the debut, but most of his body was obscured then, and it might've not even been him. He might literally just be someone else's soot power.
(The original) Christopher appears like he was genuinely a good dude but I thought about something. As a star bearer, Christopher would've known about unification, maybe not the exact details, but he would've known living dolls and shadows unify. Given that Maryrose told him that living dolls are humans, couldn't he have put together that unification kills humans before being invited? Anthony might've intentionally used the influence living dolls have on their shadows to get him to not speak up though, but that leads me to believe he didn't kill himself after the awful revelation and rather that Anthony killed him.
All in all I can't wait for Anthony to get his shit wrecked and I can't wait for Maryrose to be the one to do it.
