"I know that!" Ketar says, half indignantly, "I just..." And he trails off, because he's starting to realize that he doesn't really know what he was aiming for, and that's - yeah, that's the sort of thing that gets you in trouble. It's an uneasy realization. Before today, he would - mostly have said that he thought he did know what he was doing, he's definitely not very experienced or respected or anything but he can navigate life at court. Being a Mindspeaker makes that much easier.
...And safer, because nearly all his life he's been indispensable to the Empire, and - in a way where it's hard to use him against his will or self-interest. That's an uncomfortable realization, that maybe he's spent his whole life - seeing a nicer face of the Empire, because everyone is just a little afraid of powerful Mindspeakers, and wants to avoid giving him strong reasons to personally dislike them.
He hasn't really tried to get anyone out of trouble before, because he mostly hasn't seen the side of the Empire where people get in trouble for reasons that are fundamentally unfair.
(...It's a fair point that probably way too much of his motivation has been that Carissa is pretty.)
He shrugs. "I guess I - wish this wasn't a place that would use people in ways that are - bad for them." Not like Carissa's home country, which seems to do that on purpose even in situations where it seems like surely there's a way for everyone to mutually benefit. "But - if it is like that - if Altarrin is like that - then I guess it's important to know."
