MSN ran this interesting take on last night's episode, speculating much of what we are:
"As if in a sort of twisted, hall-of-mirrors version of Arthur Miller’s “Death of a Salesman,” Tony was reflecting on his own life through the salesman version of himself, imagining an idealized reality just as Willy Loman does."
"he was a salesperson living an apparently flatline sort of life. Arriving at a convention for work, he talked to his wife on the phone, and that woman was a bland, non-Carmela female;"
