The concept of a "goomah" (girlfriend) for a happily married mob guy is baked into that specific cake

Even when Tony and Carmella were locked in extreme mental warfare...when they went through their separation, when she helped herself to a brick of cash from his duck food locker...when SHE toyed with her OWN attempts at infidelity...yeah.

There was more integrity there, ultimately, than we'll ever see from Trump and his Slovenian trophy wife.

And Tony VICIOUSLY disciplined ANY who violated his underlying moral code. Ironic that he could do that while robbing the bank, but he did.
