A trip too far down memory lane.

In an attempt to return Cordelia's memory, Lorne arrives with a magic bottle and a memory spell. The whole gang, plus Wesley, sit down together and perform the spell, but it backfires when Cordelia steps on the bottle.

Suddenly, eveyone's memory reverts to when they were seventeen, with the exception of Lorne, who instead has passed out behind the counter.

The gang bicker with one another, discovering Lorne in the process. Wesley convinces them there's a vampire in the hotel somewhere, which they must kill as a test. They split up to find it.

Angel, or Liam as he believes himself to be, realises that he's a vampire when he comes face to non-reflection in a mirror. He attempts to hide this from the group, hitting Lorne to keep him quiet. As he chases Cordelia, Connor appears and intervenes, and the two fight it out in the hotel kitchens. Only the intervention of Fred, her memory restored, stops them.

Quiz - ten quick questions.

Trivia: This episode is the only one in season four written by Buffy and Angel creator Joss Whedon, who also directed it.

What the personality disorder test involving questions about wanting to be a florist that Fred mentions is, who knows, but it's not the first time it's been referred to in the Buffy universe. In season three Buffy episode Doppelgangland, Buffy tells Willow that Giles "even has that test to see if you're crazy that asks if you ever hear voices or you ever wanted to be a florist." And in season two episode What's My Line part one one of the questions on the careers aptitude test everyone takes asks whether they like shrubs.
