Jessica used to not be much impressed by birthdays - they were things that normal people did – then friends started making a big deal about it and she was won over.

Hank secretly likes birthdays but never tries to put much into it as he worries about being disappointed.

Brimstone was shocked at the idea of it, a celebration simply because a person exists and not for anything they did? He still doesn't quite get it but he tries to celebrate them for Karou's sake. His servants do a better job with the whole thing.

Quinlan is more into his children's birthdays now.

Andrea tends to get morose about her birthday because her mom isn't around for them anymore and she's pretty much friendless.

Anton...I'm not sure. I'm afraid I have no idea how the typical Muscovite thinks of birthdays.

Mulan, again not sure what the cultural expectation is. I can see her not wanting to make a big deal but Aurora making one anyway. Mulan wouldn't really show it but she would be pleased.
