Any time that Tris and Keth snipe at each other during Keth's magical training.
Tris: Focus, just ignore me.
Keith: I wish I could ignore you.
Many scenes dealing with Zhegorz, from his determination to get Briar to take sleeping drops, to Sandry making him her secretary, even though he can't write. There's also a scene where Empress Berenene wonders about Sandry's secretary because he's so mysterious that her spies haven't seen him.
In Will of the Empress, Sandry announces proudly that breeding mules has been her family's specialty for over two hundred years. Briar, Tris, and Daja stare at each other for a minute, and then Daja comments, "That explains a lot."
"I am not listening to you," Sandry told them loftily as the courtiers laughed. "Do you notice that I am not listening to you?" she continued. "Mark it well. I ignore you." "And I feel ignored," said Briar, rejoining them. "I am so ignored and unheard that I know it won't matter if I say, Why does it not surprise me, that the Landregs breed mules?"
Daja's skating lessons in Cold Fire. She falls over a lot.
How about the scene from Will of the Empress where Briar is challenged to an unarmed duel by one of the courtiers? Daja is with him, and starts taking bets from the crowd while Briar makes a show of taking off ALL his knives.
