Hi there. Couldn't answer in the comment section because it looked very lengthy there
So in regards to your opening for your episode 2 what if it starts with Prue being on a mission to take out the nearest demons in the city like since she discovered a new baby sister she doesn't want to lose her like Phoebe like I'm her mind she's trying to demon proof the city as Paige is still a novice witch.
Then she meets the Source who threatens to break the charmed circle again , Prue tries to attack but the Source sends her flying across the alley and then you cue the opening them afterwards it can start with her coming back to the manor and Piper tries to convince her demon proofing the city is impossible and they have to find Paige so she can learn to protect herself just as they did.
