Phoebe and Piper seem at a loss when trying to find Prue, but they have the ability to scry and have used scrying in the past to successfully find a witch.
Piper (14:24) tells Leo she couldn't find the weapon in the Book of Shadows anywhere, 2 minutes later she is looking at the Book of Shadows and the weapon. 3 minutes later she tells Darryl, 'No, still looking.'
Prue says she's ordered a bunch of equipment for digital photography, but her kit appears to include 2 large packs of film.
At approximately one minute and 43 seconds the curtain upstairs in the Attic moves as the camera is panning towards the house as if someone accidentally touched it.
Phoebe points to lot 827 and says it's at the top of the hill. The map she is looking at doesn't show the terrain, just that the lot is at the end of a cul-de-sac.
