Tairn’s refusal to trust Xaden is harsh, but he is still conditioning his wings to carry Andarna farther for Violet’s cure mission. Support with boundaries feels wiser here than pretending the risk is gone.

Andarna sides with Violet because she knows what it means to be an unknown, then makes the search for her own kind part of the hunt for Xaden’s cure. Her identity quest and his cure quest are now linked.

Violet spots the false scribe because a real one would have run toward the Archives, throws before he can draw his sword, and explains the tell only after he is dead. Her precision starts with attention.

Xaden was already halfway down the stairs before he knew Violet was in the interrogation chamber. Saving his admission that he sensed the venin until after her promise not to run makes the rescue feel suddenly less reassuring.

Before Xaden says a word in the administration building, the people waiting outside the talks stare and edge aside. Violet reads the reaction clearly: his looks draw attention, while his power and political history make them back away.

Should Violet accept the seventh-breed mission without choosing her own squad? Andarna insists they must go, Melgren refuses her squad demand, and Violet believes the mission could reveal how to defeat the venin or cure Xaden.

  • Accept Grady’s selections
  • Refuse without squad control
  • Accept if Xaden is guaranteed

The repeated “Poromiel walks” is doing so much work. Where the riot stays, whether Basgiath protects fliers, even another killing—every condition lands on the same threat, while Brennan and Lewellen already look exhausted.

Violet shoves Cat behind their squad, then cuts through the rivalry with what Cat needs to hear: the fliers do not need every Navarrian rider’s acceptance, because this squad already accepts them.
