Ep 2. Hell Hath No Fury

In "Charmed" season 4 episode 2, titled "Hell Hath No Fury", the sisters find themselves facing a new demon that preys on newly-married couples. Piper and Leo decide to get married again, with the rest of the sisters serving as their wedding planners. However, their celebration is cut short when the demon targets them specifically.

The demon, named Zankou, is a strategic mastermind who plans to overthrow the Source of All Evil and take over the Underworld. He creates a magical barrier around the manor, trapping the sisters inside with him. Zankou feeds off of the fear and anger of newlyweds, and as Piper and Leo are the only recently married couple in the manor, he focuses his attacks on them.

Phoebe, Paige, and Cole work together to try and find a way to break the barrier and stop Zankou, but their efforts are hindered by a series of attacks from demonic minions sent by the demon. Meanwhile, Piper struggles with the emotional turmoil of the situation, as she finds herself overwhelmed with feelings of fear and rage that she cannot control.

As the situation grows more dire, Leo is forced to make a difficult decision in order to protect his family. The sisters eventually come up with a plan to defeat Zankou, but it comes with a heavy cost. The episode ends with Piper and Leo renewing their vows in a more private ceremony, with the knowledge that their love for each other is stronger than any demon could ever be.

Overall, "Hell Hath No Fury" is a tense and emotional episode that explores the power of love and the lengths that the sisters will go to in order to protect each other. It introduces a formidable new villain in Zankou, and sets the stage for the rest of the season as the sisters continue to fight against the forces of evil.
