The Four Sisters, Part 1/Plot

Piper, Phoebe, and Paige burst into the tall Cupid's court with the determination of getting Coop back. Though understanding their dedication to love and Phoebe's love for Coop, he directs them to another room. In shock, the sisters see that there is a very large meeting going on in the magical community. Some of the magical beings are the Angel of Death, the Angels of Destiny, the Elders, the Avatars, and the Tribunal.

Meanwhile, Benjamin and Kyra discuss taking him back in time. The two soon are escorted away to Pixies who are well aware that Kyra has a soul and Benjamin is in Cole's body. The pixies question why Prue would put Ben in Cole's body when she could've put him in his own body.

All the while, Prue says a spell to bring back someone and the person who appears is...Neena.

Back in the meeting of the magical beings, they inform the Charmed Ones that they are the new Tribunal and that they meet because of the old ones. The sisters are also informed that the Old Ones cannot be vanquished and that Knox has the seeds of the Old Ones within him. Phoebe tells them that vanquished evil beings are being brought back and that the wasteland is an Old One, Heremus, itself.

While the sisters discuss Heremus, Tyler ignores calls from Kareem and his parents, who are all worried that something bad has happened to him. Tyler is surrounded by elderly bodies and he has a flashback of Javna attacking someone. Though he tries to leave to tell Paige what is going on, he transforms into another person...Zankou.

Back at the pixie's, Zankou attacks everyone during the ritual. However he leaves before killing Ben and Kyra, setting his sights on a witch.

As the sisters leave the Cupids, a baby cupid informs them that Coop is actually being protected from the evils and that the magical beings believe that the Old Ones will take over Earth and the magical beings want their strongest soldiers safe.

Back at Prue, she is demanding answers from Neena so that she can stop hurting her sisters. Neena lets her know that she is sad about Prue damaging her family so much and later damage more. She tells Prue to listen to her closely.

At the manor, Prue tells her sisters about her meeting with Neena. Phoebe asks her if the All can be shared between people and most of the sisters set on sharing the Nexus of the All. However, Paige is reluctant, fearing that Henry is right about magic being dangerous. Eventually, she agrees to go through with the ritual and the sisters chant.

During the ritual, Zankou attacks the sisters and Prue quickly tries to vanquish him. He explodes, leaving Tyler sitting on the floor and shocking everyone in the room. Having a realization, Prue murmurs "Heremus".
