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.
Foe Yay: According to Toby in book 1, she and Tybalt have never gotten along when she was growing up, with her being a mere changeling, although their current relationship hints at something else.
He's Just Hiding: ...Or not. The fae sometimes confuse death with a long nap. But that's justified given these are the people who put Rip Van Winkle to sleep, along with the fact that the purebloods are immortal.
Elfshot, which puts purebloods to sleep for a hundred years if they're shot with it. Too bad it's usually fatal to anyone not a pureblood...which might be overlooked by some folks who shoot them.
In Ashes of Honor, Toby finds herself kidnapped, with her hands bound by twine. However, thanks to her new super-healing powers, she can be a bit more cavalier with her own physical well-being... so she scrapes her wrists against the walls until the twine breaks, scraping away a good portion of her actual wrists as well. Doubles as Nausea Fuel!
