Regarding the Madison bit...

"
The Ashley Madison reference had me laughing. Was that a clever bit of ADR [automated dialogue replacement]?
It was. The weird thing is that in the pilot, Ashley Madison was one of his vices. When this whole thing happened, it was something that I was going to use in the season finale, when I wrote that scene, but then I was like, “Well, I already mentioned Ashley Madison. How many references can we have?” So I kind of edited it out. When we were reshooting it, this whole hack happened, so I thought this was perfect. In post, I thought, “I have to put this back in.”
