Corrected entry: According to this episode, the binding spell that Grams cast on the sisters when they were children would be automatically unbound when she died. If this happened they would not have needed to read a spell to gain their powers in the pilot episode 'Something Wicca This Way Comes'.
Corrected entry: In this episode, the Charmed Ones travel into the past, to 1975. Prue explains to Piper that one of the reasons Patty became a waitress was because, "With Dad gone, she had to pay the bills somehow." However, Patty was in the earliest stages of her pregnancy in this episode, while episode 1-3: "Thank You For Not Morphing" established that Victor didn't leave the family until after Phoebe was born.DavidK93
