It has been 10 years since Prue had her baby, was killed by Shaz, and Roger left the family. After Prue was killed Piper wanted to adopt Kristen. So she went through the courts and was granted custody of Kristen. They found out at an early age that Kristen had powers that had to do with the mind. She could enter people's dreams, make them do what she wanted, and she could feel the feeling of those around her.

So during her toddler years Kristen would go into the minds of her teachers and make them do what they wanted. Piper had to constantly go into the principal's office to bail her out. As she grew older she tried to use her powers in her mom and aunts. When she was ten years old she finally was able to talk to them through the mind and sometimes to be devious enter their dreams at night. Well she didn't get caught until one night she entered Piper's dream when Piper was having a naughty dream about herself and Leo.

Well during the dream she entered the room when they were making love and Pipe noticed her. That morning they had punished her and told her to not go into people's private dreams. They then looked in the book for ways to block her from going into her dreams unless it was urgent. They found something and ended up blocking her from that and from her controlling them through the mind. In middle school sometimes she would get into the minds if her teachers before a big test to know what to study for, but every time she did it Piper knew. To test the theory out Phoebe hit Piper on the shoulder pretty hard that it left a bruise. When Piper screamed out in pain, Kristen also did when they lifted up Kristen's shirt it ad the bruise in the same spot as Piper's was.
