There's a scene in Wicca Envy (I think it's that episode) where Piper is annoying Phoebe with a feather duster whilst Phoebe's trying to talk to Rex (I think it was him) on the phone.
I think I'm mainly going to be picking out sisterly moments for this. xD
I think part of the fun of this will be picking the moments.
That moment from "Which Prue is it..." near the beginning where the sisters are play fighting after Phoebe's told them that she's learning to fight. Literally just before Phoebe's premonition ruins the moment.
Victor/Paige, Andy/sisters that are not Prue, Prue/Grams.
Amen, you sure do dislike Victor and Prue's relationship. So much so that you've put it twice. xD
