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.
Alternative Character Interpretation: Adam as of The Dream Thieves has been getting this. Is he struggling with the anger and emotional backlash from an abusive father and taking on Cabeswater, or is he a selfish, misogynistic tool with anger issues that are never dealt with? Also Blue: strong independent woman with a judgmental streak, or cliche, hypocritical author avatar for psuedo-feminist speech?
The author has stated that Blue's judgmental attitude is an intentional flaw and her feminism is not real feminism, so her hypocrisy in some areas (claiming to be feminist while slut-shaming her cousin Orla for example) are likely intentional.
Given that Gansey views Orla in a similar way Blue does, it could be a way of the author showing that Blue's Not So Above it All and is more similar to the Aglionby boys than she'd like to admit.
A case of Draco in Leather Pants, given the fact that he, among other things, kidnapped Ronan's brother Matthew as a way to attract his attention.
Evil Is Sexy: While not exctly evil, let's just say lot of readers became big fans of Kavinsky after The Dream Thieves.
Ho Yay: Virtually incessant, and with its fair share of lampshading:
Gansey and Ronan are close enough that Kavinsky is convinced Ronan must either be in love with Gansey or want to get into his pants. (In actuallity Ronan sees him as a brother, but the Ho Yay is still heavily present.)
Ronan and Adam, meanwhile, bicker Like an Old Married Couple and Ronan's brother, Declan, either through perception or paranoia, has picked up on it. He gets visibly bothered when he sees them in close physical contact. (In The Dream Thieves Ronan puts his legs across Adam's lap, pretending to sleep when he sees his brother coming towards them. Declan seems to focus more on their contact than on the fact that Ronan is obviously ignoring him, though he may be used to that.)
Also in The Dream Thieves Ronan comes to terms with his own sexuality and we learn that he is in fact gay. He has his fair share of Foe Yay with Kavinsky, but ultimately has a crush on Adam that he himself may not even be fully aware of.
In the third book, Adam is aware of and flattered by Ronan's feelings for him, although whether or not he reciprocates is up for debate. Though that may change in the future.
Adam and Gansey have a relationship that constantly teeters on the finest edge of subtext, and even Noah has charged moments with all three of the other boys. As Blue reflects in the third installment, the entire group really is in love with each other in different ways.
Foe Yay: In spades with Ronan and Kavinsky. Not even spades, really. More like shovels.
Love Makes You Crazy: Kavinsky's...complicated...feelings for Ronan seem to have a lot to do with his breakdown at the end of The Dream Thieves.
Nightmare Fuel: Ronan's nightmares themselves. Especially when crow monsters start coming out and trying to kill him.
In Blue Lily, Lily Blue, Adam finding a bloody copy of Ronan's dead body.
