Thank you for chiming in! I understand at this point that the books have a definitive gender statement of "angels are sexless unless they really want to make an effort" - does that sound correct/is that the source your understanding of them as canonically agender (I'm specifically looking to grasp what's in-canon vs. word of god at this point, Neil's social media seems very clear from a word of god perspective), and is there anything similarly definitive in the show?

It would also be helpful to know what you think the differences are between the book and show and whether they're similar enough that they should be treated as a shared universe fandom.
