He was able to find Prue and return her safely back.However, Grams wasn't too happy about it when she found out.
After Phoebe was born, their grandmother, Penny, bound their powers in order to prevent the warlock Nicholas from killing them and possessing their powers after he was given immunity from them by Patty against her will.
Penny also erased her and Piper's memory of even being witches and having powers.
She had an on and off relationship with her and her sisters' childhood friend Andy Trudeau.
The relationship would then pick up again in their late twenties.
3 years later, herself, as well as Phoebe, were in a car accident, resulting in Phoebe getting hospitalized, Prue then blamed herself for hurting her.
Grams tried her best to keep them together so they would be able to fulfill their destiny of being the Charmed Ones.A frightened Victor went to check on Prue and noticed she's not in her bed anymore, he ran outside and saw a van, thus, making him think something bad had happened.He opened the door and found himself in the playground as well.At the age of seventeen, the boy Prue thought she was in love with attacked her incurring the wrath of an indignant Grams.According to Piper, Grams presumably used witchcraft to deal with him as the boy was never seen again afterwards.Besides this, Prue possessed the basic powers of a witch: the ability to cast spells, brew potions and scry for lost objects or people.
