Excellent story concept, and performances by Farrell and Saint James.
But there is a fundamental flaw here: Aggie knows his character is happily married. All he would had to have said would have been, "Are you suggesting that I be unfaithful to my wife? If so then you have no empathy, or respect for marriage. And that makes you a low class human being."
Then, he could have walked away. And she would have backed-off.
Of course, the writers couldn't have that realistic scenario because they had to create a story to present. Nonetheless, it still was very entertaining.
I really found myself drawn into this episode. I've never had an "Aggie" drawn to me. Usually, it's he opposite...with disastrous results.
