First appearance of Rex Buckland and Hannah Webster.
The documentary Piper's watching IS a fake and was made specifically for the show.
In the scene where Phoebe gets up from the table with Alec to talk to Prue, the tattoo Alyssa Milano has on her right shoulder, though covered with make up, is noticeable.
This is the first time that "Quake," the bar, is seen in the show. It would become the other main set, other then the house, as that continued for several seasons.
