Spin the Bottle

When Lorne tries to perform a magic spell on Cordelia to make her regain her memory, the spell naturally goes wrong in which Lorne is knocked out and the rest of the gang of Angel, Gunn, Fred, Cordelia and Wesley lose their own memories and resort to their teenage personas which has some interesting and amusing results with Cordelia reverting back to her snobbish, rich girl from Sunnydale, the street-talking Gunn, the sly and intellectual Fred, and the cowardly Wesley bickering with each other and the perplexed Angel, resorting to his own persona, Liam, before he became a vampire. Later, things get complicated when an angry Connor arrives at the hotel looking to harm Angel believing him to be responsible for Cordelia not returning Connor's affections.
