Motherland: Fort Salem and a few questions

I am watching and really enjoying Motherland: Fort Salem, which is currently in its third and final season. I saw the first 5 episodes maybe last year, then started watching the rest, and am already on season 3, episode 4. I didn't time it perfectly, and will thus be waiting for the last few episodes over the next few weeks, but if you are already all caught up then please say so in the comments and maybe we can talk about this show which I have heard very few people talk about! (Thank you, ads in the NYC subway system, and Marina Berlin, for bringing the show to my attention.)

It's a soapy, plotty, pulpy show about military witches, with tantalizing worldbuilding and lots of character moments where people sacrifice or take risks to Make A Stand or Have Each Other's Backs and so on. We follow three new cadets as they form a unit, deal with intrigue and relationships, fight various enemies, etc. I am a sucker for the super idealistic one who Wants To Serve And Protect The Innocent. There's substantial violence and goriness in this show, including the graphic deaths of innocent people, so watch out for that if that'll bother you.

Most of the characters are women; in season 2 we meet a nonbinary character. A queer romantic relationship is one of the most important ones in the show. Several major characters are Black. Most of our main characters are from the US, but we also get some globetrotting and some characters from elsewhere since events quickly take on a global scope -- and one main character is from a sovereign indigenous nation in the North American Midwest.

Now, my nitpicking questions/notes:

( Question for people who have already seen all of season 1 )

( Note for people who have watched through season 2 )

( Question for people who have watched at least up through season 3, episode 3 )

And: has the show, so far, discussed gender transition or shown us any binary trans witches?
