Yeah, but as I said, that isn't "hey, if you bang Andras, maybe he'll tell you about the book." It's "hey, Andras gave you that book, so maybe he can help you figure it out". I don't exactly remember the scene in the prologue like that, I thought it was more "we can't do anything about it, might as well use it to our advantage". It's the same thing with the blowjob thing; Rowan doesn't want to and can't stop Andras (he can technically, that option exists) from going to Alexia. But that scene doesn't resolve with a "Rowan got a hard boner as Andras went to go visit his wife".
