"How many Hawkbrothers does it take for a mating circle?"
"Only one, but he has to be flexible!"
Companions insisting they're not horses.
How Herald Alberich (with some help from Kantor) deters a pursuer (who happens to be a popular stage actor). He ducks into an inn, finds a group of young women and chaperones who are major fans, and innocently directs them outside where the actor is lurking about. Then all Alberich has to do is flatten himself against the nearby wall before he gets stampeded by the fangirls who practically chase the actor down the street.
Afterwards, his reaction (and Kantor's sniping) to Myste taking the initiative to seduce him.
Kantor: If you didn't read that as an invitation, you're denser than I thought.
Also, Alberich's first scenes with Herald-Chronicler Myste, where it talks about just how unsuited to combat she is, being clumsy with coke bottle glasses. Being Alberich, he immediately comes up with alternative training designed to all but weaponize Screw This, I'm Outta Here!.
The minor sub-plot/Running Gag in the first book about Talia and Skif repeatedly trying to have sex and failing because one of them keeps falling asleep due to their crazy schedules. They never succeed, but no one is the wiser, and Skif enjoys a reputation as a ladykiller as a result. Talia marries at the end of the trilogy, but Skif is still running wild until he meets Nyara in the Mage Winds trilogy, about ten years later.
Vanyel's grumbling about his mostly self-inflicted celibacy during Magic's Promise.
More darkly humorous than anything else... Bard Stefan complains to Vanyel's nephew Medren that he's done nearly everything to try to seduce Vanyel and is seriously considering just ambushing the man. Medren quickly advises him not to take that approach, given Vanyel does not react to... surprises well, and mulls to himself about a time when some poor idiot barged in on Vanyel taking a bath. Said thoughts go along the lines of "Grandfather did say he wanted to rebuild the bathhouse. I don't think he meant for it to happen that way."
Starwind and Moondance become the first Tayledras to make their presence known to multiple Valdemarans with they visit Forst Reach. Savil warns them about the particularities of the Ashkevrons and Starwind airily waves off her concern. The next chapter, the two of them are desperately trying to maintain polite calm when chattered at by one of the many teenage girls of the main family. Once they are able to elude her, a bewildered Starwind says that the Ashkevrons aren't a family but an army, noting that k'Vala is bigger but that's an entire Clan, not the descent of a single set of parents (Three generations, with the oldest members of the third getting ready to be married themselves, all in one household)!
Bard Lynnell finding out that the young singer she rescued off the street assumed he'd been sold to a house of prostitution. According to Stefen, she blushed as red as her cloak.
After finding and rescuing Hyllarr, an injured hawkeagle bondbird, Darkwind hits on the idea of having his father Starblade care for him, as Starblade is himself slowly recovering after being freed from the villain's control and having someone to take care of might help both of them heal. Since most bondbirds have very limited ability to grasp complex ideas or abstract concepts, Darkwind is prepared to face some difficulty in explaining his plan to Hyllarr - and is completely floored to discover that Hyllarr not only gets it immediately, but is fully capable of shamelessly hamming up the pain of his hurt wing to play to Starblade's sympathy, complete with little chirps of distress.
The bird roused again with satisfaction. :Hyllarr plays hurt-wing-eyas, Starblade feels good, Hyllarr gets many good eatings, tender eatings, tasty prey, make Hyllarr better. All good.: "You," [Darkwind] said, shaking an admonitory finger at the bird, "are going to wind up too fat to fly."
When Elspeth, Darkwind, and co land in the forest of Sorrows due to their Gate being hijacked. There they are, trying to figure out how they got there and expecting a fight, when a spirit manifests, terrifying them even more, because there's nothing anyone can do about a malevolent spirit. Then...
"Bright havens!" said a cheerful, gentle voice in her head. "You all look as if you've seen a ghost!
Enjoying yourself there Vanyel?
