Slouching Towards Bethlehem
Cordelia returns, but has absolutely no memory of who she is. The gang try to help her, including getting Lorne to read her mind as she sings, but nothing seems to help. Worse, Lorne is so shaken by what he sees from reading her that he refuses to speak about it.
Scared by the goings on at the hotel, Cordelia willingly goes with Connor when he turns up, relieved at his truthfulness. Despite being attacked by Wolfram and Hart employees, he manages to keep her safe, and refuses to return to Angel.
Dismally returning to the hotel, the gang have even worse news. Lorne has been attacked, and the knowledge he read from Cordy's mind pulled from him by a brain-burrowing demon.
