And in his delusions he made himself out to be the Fisher King, the keeper of the Holy Grail who in his mind was his one surviving daughter, Rebecca.
The Knights of the Round Table, the ones who search for the Holy Grail... that was the BAU. He found out all these small, personal details about us from the letters I wrote to my mom. [And if he hadn't done that, none of this would've happened.]
