Piper Erases the past

Piper and Leo have had a big argument over Wyatt. Leo has orbed out and Piper is sitting with Wyatt thinking over what she can do.
Piper sat in the armchair with an evil look on her face. "Thinks he can demand this and that from me. Huh! Who does your daddy think he is hm?" Wyatt gurgled but piper just looked on. "Piper? What are you doing?" Piper looked up to find Paige standing in front of her, arms folded. "What? Nothing just thinking about what Leo said," Piper looked down on Wyatt. "You and Leo have had another fight haven't you?" Piper looked back up again. "NO! We've just had a bit of a misunderstanding that's all." Paige walked away in disbelieve. Piper called Paige back. "Could you look after Wyatt for me." Piper passed the baby over to his aunt and walked off leaving Paige looking on in astonishment.
Meanwhile back in the White lighters land Leo is thinking about his actions too. "What was I thinking? I have a beautiful baby boy and a wonderful wife. It was too much to demand that I allow Wyatt to train at this age." Leo walked over to the door, and orbed out.
Back at the manor Paige has taken Wyatt out for a walk, phoebe is out on a date with Cole and piper is up in the attic. "Come on there must be a spell in here somewhere. See the future, see the past, re-write history, and change the past. Aha there it is," she looked down at the spell and read it carefully. "Can cause weird effects on many people including outside the witch realm. Well I suppose that means I don't get chicken for dinner," She laughed a little and got on with the spell. "The past is ill- written and needs to be changed, for better or worse through the summer night rain. Pour down before me and let me re-write, what has been illuminus written and destroyus the light." A blast of light fills the room and Piper is pulled into a different world. Pictures and memories flash before her until she reaches the memory of her marriage o Leo. "We were happy. What changed? No piper, stay on track, we're here to erase those memory's." More pictures came and went until she freezed a picture showing her and her sisters (phoebe and Prue) with Leo for the first time ever. "Lets do some erasing. For memories forgotten and for memory's re-used, let this picture I see before me, erase the past before my eyes." Piper looked at the picture and all of a sudden it vanished.
"Paige? Phoebe? Anybody here?" Piper looked around but nobody was in the house. "Piper have you seen that spell I was working on?" Piper looked up. "PRUE!" Prue was standing in the doorway. "Ur yeah Piper so have you seen it?" Piper ran over to her. "But your dead. How did you come back?" Piper looked up and down her supposed to be dead sister. "Are you ok piper." Piper nodded. Prue took piper to a nearby chair and started to leave the room. "Prue? Where's Paige and Wyatt?" Prue looked confusingly at Piper. "Wyatt? Well I don't know WHAT your talking about but Paige, we haven't seen her for over 20 years piper," and she left the room. "My baby..I've erased my baby as well...."
