i think the loss of jack mackey who was practically lee's alter ego, in a way. they were deeply close. i think the loss of jack mackey may have emotionally closed lee up toward friendship. that really hurt deeply. >> this is out of curiosity. based on what you shared with us tonight about mary lee and her personality, did she have a lot in common with a lincoln's wife? >> the question is did mary lee have a lot in common with mary lincoln? outwardly, you can see some of it. -- explosive is too little a word. a volatile temper and temperament. certainly, a want of frugality. , a nice way to put it. that, i don't pretend to understand what mary lincoln's psychosis was, if you could call it that. there is no question they were both difficult for their husbands. they both caused their husbands and there's. worst, they cause their bit -- husbands embarrassment in front of the professional peers and colleagues. they were not have been good political wives as mary was not. >> thank you. >> thank you all, again, very much.
