Charmed - Season 8 Episode 20 -

Dumain gets the hesitant Triad's okay to isolate the Charmed Ones by making them look unwilling to protect any of their magic friends. So he makes sure they get appeals but can't respond, being spell-bound by their private obsessions: a love-life with Coop for Phoebe, a home for Leo with Piper, a ring-conjured meditative isolation for Paige, so demons vanquish the messengers or worse. That allows Christy to win over Billie, who betrayed their secrets, completely and help send the trio to the underworld.
