the line Luthen said to young Kleya about how all she knew was hate and that wasn't enough. She needed to know where to put it and feed it until she knew where and when and how to use it.
I can't remember the exact line, but that was some heavy shit.
there's something real there about the instant, righteous hatred of youth for injustice... and the patient, nuclear hatred of long experience. all those tactical losses stacking, building and feeding the resolve and fire of the long strategy.
Meero deeply underestimated Luthen's hatred when she chose to confront him the way she did... assuming he wanted to live another second longer than he needed to for the job. I like that he got to call her out on her pride too. she didn't really process it then, but I think it sunk in by the time she was in her cell.
