Having learned the truth about Harry at the end of Season 2, Asta is no longer just his confidante; she is his handler, his moral compass, and reluctantly, his general in a guerrilla war.

On the other, he is now "Dr. Harry," a man who has tasted honey, hugged a crying child, and, most damningly, developed a conscience.
