Power Advancement in 2009

Season two episode Morality Bites led fans to believe Phoebe's third power was supposed to be electrokinesis or the ability to generate electricity. Although it has never been confimed it is often assumed that in that alternate future Phoebe shown in Morality Bites received the power of electrokinesis. However it is also theorized that the ability she used to kill Cal Greene with was actually an advancement of her empathy power, i.e. passing on harming emotions through the medium of electricity. This would explain why she snuck up on him and aimed for the brain rather than just throwing a bolt of electricity at him as anyone else would with the power of electokinesis. It also exaplins why Leo kept telling the Charmed Ones in the future that Phoebe's power, singular, can kill now. At the time of Morality Bites she only had premonitions, therefore probably being the power they were referring to hinting that the power she used to kill Cal Green with had developed from her power of premonition and as we know her empathy power developed from her premonition power which means an advanced version of her empathy power that allowed her to kill with...

Her father and maternal grandmother argued about Victor being merely human and thus unable to protect his own children from the supernatural. A disgruntled Victor eventually left his family.

At the age of 10 Phoebe was transported by a spell cast by her future self to the year 2002, where she met two older versions of herself, her sister Piper, Piper's husband Leo Wyatt, and Phoebe's future ex-husband Cole Turner. Cole protected her from the demon Kurzon and then she visited the realm of Whitelighters with Leo. After she helped the older Phoebe listen to her heart about marrying Cole, she returned to her own time, where Penny quickly erased her memory of the time travel.

Phoebe has had the most tumultuous love life of all the sisters.She is probably the only Halliwell to have the take-a-chance gene. Early in the show, Phoebe's former boyfriend Clay came into town after helping steal a cursed urn in Egypt. He tried to have Prue auction it off, but when she learned it was stolen she had it removed from the auction. The guardian of the urn attacked Clay, and the sisters saved him. Their relationship was not exactly successful, since Clay essentially tried to give them a curse.

[i]She started a romance with district attorney Cole Turner,who turned out to be a half-demon named Belthazor, sent to kill the Charmed Ones. Although Cole had started out using her to get close to the sisters, they fell in love. When Cole's demon half was revealed to the Charmed Ones, Phoebe helped him fake his own death and then let everyone, including her sisters, believe he was dead.Phoebe then spent time researching Cole's past, confiding only in Leo that she did not really vanquish Cole. She eventually told her sisters, which strained their sisterhood. Cole and Phoebe had a chaotic romance at best, constantly threatened by each their conflicting...
