Why would he suggest she stopped working undercover when everyone now knows that she stopped working undercover in the '90's thereby making the whole "undercover spy" point moot. Even when she did work "undercover" it's not like she was a deep undercover agent.
She (among many others) was "blown" in 1994 by Aldrich Ames. She has not worked overseas since 1997, when both she and Joe came home and got married. She had twin sons in 2000.
Under no circumstances was she working under cover for the CIA.
I believe someone said Joe was a horse's a**. I concur.
"Even when she did work "undercover" it's not like she was a deep undercover agent."
Well, she was deep under Wilson's covers.
