Doing a rewatch and oh my God, Phoebe turns out to be such a hypocrite! She calls Piper selfish for wanting to marry Leo on the DL because they're soulmates, yet later she goes and marries a fucking DEMON and becomes evil because she is in love with Cole.
In S1E17 "That 70s Episode" the girls meet little Prue and Piper, who look around 6 and 4. Patty is also newly pregnant with Phoebe. Yet in S3E1 "Magic Hour", Prue tells Phoebe they were 3 and 1 when she was born. It makes no sense.
Just doing a rewatch, and it seems like the poor old lady just vanishes. They don't address her death or the fact she is technically missing. She is just gone and Prue takes the wand. Surely this would have been suspicious as if Prue killed her and stole it, especially as it's broken when she gives it to Jack at the bar.
