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.
Complete Monster: Regal, in spades. Thinks nothing of murdering his own teenage nephew with his bare hands, partly to cover his tracks and partly because he just hates him; enjoys torturing people and having them tortured, including his own subordinates; kills his own father and tries to kill his own brother (several times); is incredibly self-centred with delusions of grandeur; villifies his heroic brother and sister-in-law as incompetents and traitors (respectively); sacrifices half the kingdom to Chaotic Evil pirates because he only cares about being king of the other half... yeah, he's kind of a dick. His only chance of redemption turns out to be Brainwashing For The Greater Good, and that still doesn't save him from some well-deserved Laser-Guided Karma.
Ho Yay: Between Fitz and the Fool, which starts at a small scale in Royal Assassin. But the smaller moments in Royal Assassin turn into much bigger and obvious instances in Assassin's Quest.
Most obviously when they see each other again. The Fool practically falls over himself to hug him since he's just so glad that Fitz is alive. For a while after, the Fool isn't so teasing to Fitz either, and also gets more protective of him.
It doesn't help that Fitz is apparently "the Catalyst" and the Fool is the White Prophet, and is determined to follow him.
Starling outright says that the Fool is in love with him. She also says that the Fool is a woman, so their relationship could be Ship Tease instead. Maybe.
Also Burrich and Chivalry, since Burrich was completely devoted to Chivalry.
Fitz reassuring Verity of his belief in him. Verity mourns the fact that Chivalry is dead, and wishes that he could follow someone as self-assured and capable as his brother. When he asks Fitz if he's ever felt that way, Fitz only quietly looks at him and assures him that he does.
All the glimpsed moments of Burrich taking care of his friend—Molly and her baby, Nettle.
Harsher in Hindsight: The Fool's initial dismissive view of Starling as someone who can't understand when a man looks at her without desire now seems terrible when Fitz learns that she was raped; first by the Raiders, then by Burl's men.
The Scrappy: Starling is presented as a strong, independent, Ethical Slut, and the Veronica counterpart to Molly. She's an arrogant Jerkass who's interested in Fitz mostly for the legend she can write about his actions so she sells the information of the daughter that he desperately wanted to keep away from royal politics, just so she could follow him on his search for Verity. She stays enormously self-centered until a good way through the Tawny Man books.
Molly herself, for some, comes as selfish and lied about not being pregnant.
Tear Jerker: The first book ends on one, second book ends on a big one, THE ENTIRE THIRD BOOK IS ONE.
The quiet moment in Royal Assassin where Fitz realizes that he has nothing outside of his service and obedience to the King.
Patience: Fitz? What will you do?
Fitz: What I am told. When have I ever done otherwise?
Fitz meets Hands again in ''Assassin's Quest and Hands turns away from him, disgusted, since Fitz's possession of the Wit has been revealed by now.
Verity and Kettricken being separated again, just not long after they've been reunited. The reunion wasn't all that heartwarming either; Verity could scarcely remember Kettricken, or feel anything else for that matter.
The Woobie: Wow, who isn't in this trilogy? Regal, probably.
Iron Woobie: Fitz, poor Fitz, who probably suffers the most during the whole trilogy. He's nearly killed at fifteen, then again when he's barely eighteen (he fakes it) for possessing forbidden magic; both experiences rob him of his youth and vitality, and at the end of the series, he doesn't even get the girl. This is still not including all the other crap he has to trudge through during the trilogy.
Jerkass Woobie: Sure, Starling might just be interested in writing a song to make her famous but since she's barren from a botched abortion, she's only interested in making sure she can take care of herself when she's older, knowing that she won't have any children to do so.
Other special mentions for Woobie-ism are Burrich, Kettricken, and Verity.
Moral Event Horizon: Kennit seems to divide the fanbase. According to some, he never really crosses the line, on account of being a Complete Monster. According to others, he stays on the very edge for quite some time, but then he rapes Althea and blows all his chances of redemption.
It can come off as heartwarming (if you assume that by this point Fitz has damn well earned his happy ending or as Mood Whiplash (if you feel like everything settles down a little too conveniently for Fitz in the end.
Ho Yay: Fitz and Fool again and this time on an even bigger scale.
They share a few kisses in the last book, under the pretense of sharing power and giving back memories.
The Fool gives him the nickname Beloved. It becomes more Ho Yay-tastic when the Pale Lady reveals that married couples exchange names, and since Beloved is supposed to be The Fool's real name that means that The Fool is calling Fitz his husband. Fitz even goes as far as calling The Fool Fitzchivalry when he thinks The Fool is dead.
And then Fitz and The Fool almost end up together. Fitz tells him that he will choose him over Molly, but The Fool pulls a I Want My Beloved to Be Happy.
Tear Jerker - Late in Fool's Errand and in Fool's Fate.
Wangst: Played for laughs and for drama in the chapter "Elfbark" in Fool's Fate. Fitz is sneaked a massive dose of elfbark, and the drug's effects have him seesawing between bouncing-around hyperactivity and soul-crushing depression, during which he laments that everything he's ever done has been worthless.
The Rain Wilds Chronicles:
Hollywood Homely: Alise, with her red hair and freckled complexion, seems to be this.
