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: Entreri's For the Evulz moment from the main page. Alternatively, it's something of a punishment/warning to Regis, who faked having a contagious disease to try and get them tossed off the ship ("attempt to slow us down again and see what'll happen to the people around you" sort of thing) as well as being a form of twisted revenge against the captain of the ship for making him get off early.
Foe Yay: The way Entreri reacts to Drizzt's rejection in "Streams of Silver" is just hilarious - like a disappointed fan boy. In fact, every time Drizzt and Entreri are on the same page expect Foe Yay to follow, especially from Entreri's end.
Fridge Brilliance: Drizzt and Entreri probably would have thrived in each others' bodies. It's noted at several points that Entreri would have prospered as a drow in Menzoberranzan, to the point where even the bigoted dark elves admit that he's drow in everything but skin color. On the other hand, if Drizzt were human he never would have had to put up with Fantastic Racism to begin with, and without the goal of earning a place for himself, his prowess might have made him grow proud...
On the other hand, Drizzt was born into incredible privilege, even by Dark Elf standards, and raised mostly by his contrarian father/ weapons trainer who did some work to shield him from the Always Chaotic Evil nature of the society. Enteri was a street rat who most likely became a sociopath because he grew up in an environment where he had no family and had to be absolutely ruthless to survive, perhaps their personalities aren't as unexpected as they might seem.
Ho Yay: Lots and lots of it. In The Halfling's Gem the captain and Drizzt get really friendly on their journey; culminating in the captain stating that Drizzt looks more handsome as himself rather than looking like a surface elf.
Nightmare Retardant: An odd variation that only comes about because of a retcon to the Dungeons & Dragons rules. It's emphasized that only fire can kill trolls in Streams Of Silver, and an anecdote is related of many a scavenger or predator that had come across a severed troll body part only to be horribly killed from the inside out as the troll regenerated. However, in another Salvatore book set in the Forgotten Realms (one of The Cleric Quintet novels), the rules had since been expanded to include acid as a way of putting a troll out of commission permanently, and the characters use both acid and fire on trolls. Now, what's in a stomach?
What an Idiot: Did that mage apprentice really think he could control a demon from the Abyss?
