Episode 84 of "Angel"
s04e18 Shiny Happy People

Cordelia lies unconcious while her offspring stands next to her. Angel and the gang are suddenly clueless and think that the woman has just arrived, assuming she is in trouble. She tells them that she needs help destroying the extra demons that have been surfacing since the darkness came. She tells the gang that if they want Cordelia to wake up, they will need to help her. They follow her around town, where everyone appears to be kneeling before her and praising her. One man named John calls her a monster, saying she isn't as good as she claims and attacks her. Angel viciously intervenes and beats him within an inch of his life. Afterwards, Fred is frantically trying to get the woman's blood out of her shirt from where she was attacked. Fred scrubs so hard that her fingers bleed, but still cant get it out. When she goes to break the bad news to the woman, she sees her perfect face has been replaced by maggots. Fred keeps this to herself. A week later, Fred visits John in Psychiatric hospital. He tells her that it is Angel's mission to destroy the being. Fred rushes back to the hotel, which is full of people worshipping the woman. She tells Wesley about John's suspicions, but he and the rest of the gang have been brainwashed by the woman. As Fred leaves, Wesley tells Angel and the woman what she said. They prepare to hunt her down, as she is now a threat.
