Season six of Charmed finds the benevolently bewitched Halliwell girls under the protection of a new "Whitelighter," or guardian angel. With Leo (Brian Krause), the father of Piper Halliwell's (Holly Marie Combs) son, Wyatt, having decided to become a Whitelighter Elder, his replacement is Chris Perry (Drew Fuller), whose unorthodox behavior leads the "Charmed Ones" to suspect that he is not one hundred percent angelic (though Piper is clearly attracted to him). Elsewhere, Phoebe Halliwell (Alyssa Milano) struggles to adapt to her newly found "empath" powers, which enable her to experience the emotions (and sometimes the pains) of others; she also falls in love with Jason Dean (Eric Dane), who is none too thrilled to discover that Phoebe and her siblings are witches (even "good" ones). Paige Halliwell (Rose McGowan) likewise falls in love with Richard Montana (Balthazar Getty), thereby enmeshing herself and the other Halliwell girls in a deadly feud between two magical families. And Piper's infant son, Wyatt, exercising his incipient force-field powers, capriciously messes up his mom's love life. Amidst all this activity, there are the usual forays into the past and future, and the vanquishing of various demonic forces who just can't leave the Halliwells alone. The season ends with a treacherous foray into an alternate universe in which evil is good and vice versa -- and it's all the handiwork of Leo and Chris' Whitelighter mentor, Gideon (Gildart Jackson), who is clearly up to no good. With chaos erupting all around her, Piper, who has been impregnated by Leo, gives birth to her baby...also named Chris.
