Question about a character in BH

In the epilogue of BH Taralak Veed is basically psychologically shellshocked - after all of his prodding, he's finally gotten to see the monstrous side of Icarium and he's absolutely horrified. I was curious about Icarium back on the boat and his interaction with Veed - there is clearly an undertone of menace in their talk. I'm curious, at least from how I read it, it seemed like there was an awareness on Icarium's part there: it felt like he knew what had happened and that the tables had been somewhat turned on Veed (where before Icarium had been miserable on the boat). Am I reading too deeply into it, or did Eres heal him in some way that gave him awareness after he goes berserk?
