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: If the sisters are innately magical even without their powers, as we see when they go back to save Melinda in episode 3-4, how are Piper and Prue frozen by little Piper?
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.
Correction: When Barbas makes the girls relive their worst memories, Piper's is her father leaving "for the last time," implying that Victor left and came back several times before leaving for good. Given Victor and Patty's rocky marriage, this would have been another of those periods when he was gone and Patty had to make ends meet on her own.
Correction: Grams bounded their powers including spell casting and potion making, so when she died only their spell casting and potion making powers were unbound, Phoebe still needed to read the spell to gain all their powers back.
No. Grams said their powers, that includes all powers. If they had all powers reading from the book would not be needed.
