These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Accidental Innuendo: After it is remarked that it is StarGleam's second time out hunting, we get this gem: "she'd had her first time when she was a littlekit and she and FireStar had snuck out together that's why he chose her as his apprentice_." Squick.
"Wll u be my mat" [GayStrip] ESked.
Anvilicious: Everything having to do with religion and homosexuality.
Part of Blackstar's reasoning for falling in love with Stargleam is that she beat him in battle, something the real Blackstar would be far too proud to admit.
Graystripe now hates Firestar, calls him an idiot, and says he's a mean cat.
Hawkfrost betrays Tigerstar simply because Stargleam is kawaii.
Daisy, now FoxDaisypaw, has decided to become a warrior. She is also being trained by Cloudtail, practically setting her up for truckloads of Die for Our Ship.
The fic takes place after Sunset, meaning it would be set in the lake territories, but the mention of the Highrock and Moonstone suggest that it is set in the Old Forest.
Everyone apparently seems to be very happy that ThunderClan is being ruled by an apprentice six moons and three days old.
Why exactly is Hollyleaf working with Tigerstar again? Canonically, she's a warrior code-obsessed Knight Templar who went through extreme Break the Cutie and Sanity Slippage, so why is she suddenly working with one of the most coldhearted and cruel villains in the series, who broke her precious Warrior Code multiple times? And why does she try to kill Firestar if she only has a grudge against Leafpool and Squirrelflight? And why is she one of Three now?
Misaimed Fandom: The author believes that StarClan can solve all problems and that nothing will go wrong if the Clans follow their path. She doesn't realise that, although StarClan is worshipped like God, their power is actually limited, they choose to play The Watcher instead of God, and are, if anything, used to criticise fanatical religious bigots like her.
