The Halliwell Manor shakes. The P's come running down the stairs and Phoebe helpfully announces, "oh no! Not another after shock!" Thanks, Phoebe. I was almost there but now I really know what's going on! Phoebs says Prue is the only who who likes earthquakes.
The girls are tidying up in the kitchen when Prue gets a whiff of something foul. Piper has already smelled this smell and thinks it's coming from the basement. She called someone to check it out, all without ever discussing this with her sisters because exposition needed to happen now. In fact, the gasman has just arrived.
Prue freaks out because they are hosting some auction-house-related dinner at the Manor. Phoebe assures her that everything will be okay.
