GREAT STARCLAN YOU WRITE A LOT
anyhoo:
bramble/squirrel: I hope at least he confided in her!! Maybe he thought it didn't matter but it'd have been nice to know he trusts her enough to tell her about that. It would make sense later on too.
ashfur: "He's loyal" apparently. Idk that's a weird thing.
crowfeather: A pov book would have been kind of infuriating...
med cats: Don't forget Feathertail told Leafpool to tell Crowfeather a thing, whether it's a Moonpool dream or not (I forget)! If StarClan says it's okay it's probably okay.
Med cats: Actually Spottedleaf was a warrior apprentice before a medicine cat apprentice! But that was only because the medicine cat at the time *had* an apprentice (even though he had his name), you can't have a medicine cat with an apprentice with an apprentice. She switched over pretty quickly after the old medicine cat died. But yeah Cinderpelt was on the road to be a warrior but then her destiny got changed...
Firestar and Sandstorm: The fate of their relationship is kind of elaborated on in the final book!!! I can't say any more, it'd be spoily. I don't know about Graystripe though! I think Silverstream's okay with Millie but what does Graystripe want? Maybe he ignores both of them and goes to hang out with some other cat. I don't know.
Polyamory: That's probably a thing and maybe the StarClan cats understand that it's bound to happen, I don't know...
Darkstripe: He never redeemed himself really! He tried to kill a kit and was willing to let his Clan get destroyed except for Bramblepaw and Tawnypaw (even Goldenflower would have died!) and then fought against the Clans instead of for them, he doesn't have much going for him unfortunately. Dustpelt and Longtail redeemed themselves in the end!
Graystripe being dead: People brought up temporary deputy because Hawkfrost was temp deputy when Mistyfoot had wandered off! Except nobody knew if Mistyfoot was alive or not, if she was alive why would she have abandoned her Clan??? Graystripe, everyone saw him got caught so he's not dead. If he died later nobody would know but it didn't seem like the Twolegs wanted to kill the cats, they were feeding them after all!! So Graystripe was more likely alive than dead whereas Mistyfoot, most cats thought she was dead. So it's a bit different even if some cats do think Graystripe is dead.
Graystripe as leader: Whitestorm thought Graystripe would make a good deputy (and by extension leader) that should say something. Also there never seems to be a consensus as to what a "good" leader is, Tigerstar was a really good leader for ShadowClan for what it's worth! I think as long as their kits get trained, they respect borders, their Clan gets fed, they're not a bad leader. Whether they choose to fight a lot or not has no bearing on whether they're a good leader I don't think! Unless they fight when every cat is starving or injured, then that's bad. But Graystripe wouldn't do that either he's loyal and he cares.
SkyClan: There was lots of time between FQ and Midnight, maybe Firestar said "nobody ask me, the quest went well but you're not to know what happened okay if you ask i'll be Angry." I don't know though it is kind of strange especially since living cats learn that there were once five Clans later on, even though in FQ everyone wants to keep it a massive secret??? Idk it's odd.
Manga: There are four trilogies, Graystripe's saga, Ravenpaw's Path, Tigerstar & Sasha and SkyClan & the Stranger. Graystripe's saga takes place between Dawn and The Sight, ending with The Sight; I usually read it between Sunset and The Sight. Ravenpaw's Path takes place between Firestar's Quest and Midnight. Tigerstar & Sasha kind of overlaps A Dangerous Path and goes as far as the time between The Darkest Hour and Firestar's Quest so I read it in that gap. SkyClan and the Stranger takes place shortly after SkyClan's Destiny, which in turn is set six moons after Firestar and Sandstorm leave SkyClan. There's also The Rise of Scourge, which details Scourge's rise to power, beginning with him as a kit and ending with his killing Tigerstar in The Darkest Hour. The beginning of it is set in the same time period as later chapters in Bluestar's Prophecy, so I usually read it between BP and Into the Wild. The manga aren't great but they are nice for background stories! I don't really like them but hey, they provide backstory. (Although I did cry at the third Tiger/Sasha book!!) The Rise of Scourge is probably the best art-wise, but it's not a whole lot better than the others story-wise.
Spoilers: It's inconsistent whether they spoiler at the beginning or not! Like some allegiances don't list a cat as a warrior when they become a warrior in the first chapter but then some mention warrior names when the cat becomes a warrior halfway through the book, why.
