At the end of this episode, Phoebe is featured in 415, the magazine Prue briefly did photography for.
Final appearance of Paige's friend Glen.
The witch doctor asks if they've ever vanquished a demon in the house. The girls reply only about a hundred (give or take another hundred.) The previous episode was the 100th, therefore at least 100 vanquishes, many of which were done at the house.
The church in this episode is the same church Phoebe got married in last season.
After the witch doctor captures Big Mama (the ghost/poltergeist), he says, "...your house has been cleansed.". This is very similar to the ending of Poltergeist when Zelda Rubenstein's character states, "this house is clean.".
