Character mistake: The number of years that Sal has been dead and the number of years that he and Sophia were married, constantly changes. In Season 3 Episode 5, Sophia says that she and Sal were married for 52 years. In other episodes, she says he's been dead anywhere from 22-30 years. If that's the case, given that Sophia is 80 at the start of the show, Sal would have died when she was about 50. Meaning that they would have had to be married since birth to be married over 50 years.
