The love Paige (Rose McGowan) expresses for her new sweetie, Richard Montana (Balthazar Getty), embroils the Charmed Ones in a deadly "magic feud" between the Montanas and the Callaways. Things reach the crisis stage when Richard's dead lover Olivia Callaway (Rachelle Lefevre) takes over Paige's (Rose McGowan) body. Elsewhere, Leo (Brian Krause) is suspicious when Chris (Drew Fuller) embarks on a secret Whitelighter mission to the Underworld; and Phoebe's (Alyssa Milano) empath powers cause her to obsess over her sisters' innermost feelings -- and to talk about them at great and tiresome length! ~ Hal Erickson, Rovi
