{{Bookman likes to wear traditional Chinese attire, so it leads me to believe he’s also got Asian descent in him like Lavi. I think that’s a given already.
But I also like to think that, since he was witnessing events between the Noah, that Bookman was originally doing most (if not almost ALL his work) in Asia up until he got Lavi as an apprentice. I can imagine more supernatural things going on in Asia and Bookman having a larger base knowledge of the region, so he mainly based his work in Asia. It’d explain his more stoic stance since Asians don’t necessarily believe in showing pain, since it’s viewed as a weakness.
And for the past thirteen years, Bookman’s been traveling the world a lot more so he can give better knowledge to Lavi instead of being region-specific. I like to think the Bookmen that aren’t in Asia are somehow a little more approachable and technically slightly friendlier, so it might vaguely explain why Lavi has a bigger heart compared to seeing hospitality and general kindness from Asia to Europe to America to Africa, etc.
So I think that Bookman might be more Chinese than anything else. Sticking to traditional views and attire, etc.}}
