There is some good, if terse, exposition here with Hrathen sorting through his feelings. I don’t think he really wants to come to any answers right now. Logic has lead him astray before, and now that he’s doing what he feels is right, he doesn’t want to pause to give himself a chance to consider the ramifications of what he’s done.
Again, Sarene has fulfilled her purpose in the book. She’s thrown chaos into Hrathen’s otherwise-orderly life. However, her chaos here—just like the chaos she caused in Elantris with her food—eventually proves to be a good thing. It inspires change for the better, even though that change is painful.
And, of course, I remind the reader here that there is something odd about Hrathen’s arm. I’ve only mentioned it in a couple of places, so I don’t expect people to remember what is going on here. I actually forgot to have the sleeve in the original rewrite. I didn’t even think to notice that his Dakhor arm would be exposed to Sarene in this scene. . . .
