Apparently, another perk of being a world-ending Revenant is the freedom of being a sassy smarty-pants at any given time. After all, who's going to stop him? Good old Aeyr.
I feel really dumb now. I mistook the statues for guards and the "terrible situations" text made me think Aeyr was a captive (even though he doesn't seem restrained), but it's just referring to Aeyr being a revenant.
To clarify my earlier comment, if the emperor had Aeyr captive, he is in the presence of people who are dangerous to leave alive, yet they have boatloads of juicy information and just getting rid of them may bite him later on. As such, if the emperor is a rational man, he will realize that he is in a tricky situation, but if he's not, then he may think that just getting rid of them will solve his problems.
That said, even though Aeyr is just barging in, the emperor's reaction is still going to be interesting. I can think of several things the emperor can say to improve his standing with Aeyr, provided he hasn't burned that bridge by earlier actions already. I can also think of several things he absolutely should not say.
