That old black magic is back.

The dark magic Angel performed to make Sahjhan material proves to have horrific side effects. A wave of translucent, parasitical creatures infests the hotel, crawling into people and killing them through dehydration.

With Fred infested, and the gang under siege, Cordelia comes to the rescue, manifesting a demon power which rids the hotel of the creatures. Wesley, meanwhile, agrees to help only Fred, saving her with a stiff drink.

Danger over, the gang still can't relax, as Fred tells them the Destroyer is on the way. A portal opens in the lobby, and a monster and young man leap out. Swiftly despatching the demon, the boy turns to Angel with the words, "Hi, Dad".

Trivia: Cordelia's correction of Angel when he says that it never snows in Southern California is a reference to the Buffy episode Amends. "Did once", she says, reminding him of the mystical snowfall that prevented him killing himself by sunlight in a torment of regret back then.

A bit more of the Hyperion Hotel's geography is revealed in this episode. There's a pool and a huge kitchen, as well as many creepy corridors.

Groo's mother's name was Pomegranate. But he's never heard of the colour purple before.
