YMMV: Small Favor
- Fridge Brilliance: When recovering from the aquarium assault, Mouse spends some time licking Harry's hand, the one that has gone numb from his use of Soulfire, and it helps dispel the pins-and-needles sensation. Later in this book we learn from Bob that Soulfire consumes a portion of the practitioner's soul for fuel, and Bob has said previously that soul-stuff can be traded by close, emotional contact, and we already know that Mouse, as a Temple Dog, has supernatural senses. Mouse noticed the damage to Harry's soul, and was restoring it with his own.
- Fridge Horror: When briefly talking to Harry about what the Denarians did to her she says only they did "things". Harry comments about having been there and his own experiences. Unfortunately the only incident Harry uses the term "things" about was a heavily implied rape by Bianca's people back in Grave Peril, which, given that Ivy is naked, leads to questions about exactly what was done.
- More Fridge Horror: The fact that Nicodemus, had he not taken the bait and sought to capture the coins and Sword, would have given Thorned Namshiel's coin to Ivy ... and thus, unwittingly handed the Archive and all its knowledge over to the Black Council. We know it's the Fallen, not its host, who's in charge in Namshiel's case because of how he's referred to, so if Uriel is right about him, Cowl's crew would have gotten the god-caliber agent they'd been trying to produce in Dead Beat.
- Harsher in Hindsight: When it is all over, Harry is resting on the Water Beetle after being rescued from the ice cold lake water. Because Thomas gave him dry clothes and hot coffee, Harry tells him he will leave everything to Thomas in his will. Thomas replied, "Cool. Next time I'll leave you in the water." Roughly two years later, Harry would be shot off the bow of the Water Beetle and falls into the waters of Lake Michigan, where he dies.
- Most Wonderful Sound: Wagner. It's back and brings hope to Harry and company in their darkest hour.
- One-Scene Wonder: Eldest Gruff appears for less than four pages. And they are fantastic.
- Rewatch Bonus: Re-reading this one, you'll notice all the times when Harry's train of thought veers away from the notion of using fire-magic, because of how Mab tampered with his memory.
