Angel Investigations meet an electrifying young lady.

Desparate to find and recover Cordelia, Angel takes the gang on a dangerous mission to obtain a relic, the Axis of Pythia, which he believes will let him achieve his aim.

However, their break-in to steal the Axis is disrupted when they run into another thief - the electrically-charged Gwen. Tussling with her, Gunn is killed when her powerful charge stops his heart. She stops to revive him, then escapes with the Axis.

Delivering the Axis, Gwen is double-crossed, but fortunately Angel arrives to confront her, ending up saving her instead. As a mark of gratitude, she gives him the Axis.

Meanwhile, Cordy's up in heaven, bored out of her head.

Quiz - ten quick questions.

Trivia: Alexa Davalos, who plays Gwen in this episode, is soon to be seen in The Chronicles of Riddick, the sequel to sci-fi horror movie Pitch Black. Her character is called Kyra.

Gwen's second name is Raiden - possibly a reference to the Japanese thunder god Raiden, who apparently also likes to devour people's navels. Yes, he's concerned with thunder, lightning and belly buttons. A possibly more familiar version of Raiden is the character Rayden in Mortal Kombat, who also controls electricity.

Both the Elusian mystery, Dinza and the Pythian Axis come with Classical Greek references. The Elusian mysteries were a series of secret rituals followed by one Greek cult. The Pythian Axis is said in this episode to be forged out of the Delphic oracle, which sounds a bit harsh as the oracle was a priestess, based at Delphi, who uttered cryptic prophesies.
