"Chosen" is the series finale of the television series Buffy the Vampire Slayer, the 22nd episode of season 7 and the 144th episode of the series. It was written and directed by series creator Joss Whedon and originally aired on UPN on May 20, 2003. The Buffy story would not be continued beyond this point until "The Long Way Home", a comic book, in 2007 and the Buffy and Angel saga would end in the Season Twelve series in late 2018.
Plot
A bloody Caleb rises and Buffy finally kills him with the scythe by slicing him in two from the crotch up. Angel has brought an amulet intended to be worn by someone ensouled, yet more than human. He tells her he will fight alongside her, but she turns him down, asking him to instead organize a second front in case she loses to the First Evil. They discuss Spike, his soul, and Buffy's feelings for him, with Angel clearly unsettled and jealous. When Angel asks whether he has a place in her future, Buffy explains that she still needs to grow up; there might be a future for them, but it will be a long time coming, if ever. Accepting this, Angel walks into the shadows, just like on the night they first met. As all this occurs, Spike watches unseen, with the First in Buffy's form by his side.
Back at the house, Dawn angrily kicks Buffy in the shin for having Xander try to take her away from Sunnydale. Spike is in the basement, working out his anger on a punching bag with a crude drawing of Angel's face on it. He asks for the amulet, and she explains that it is very powerful and meant only for a champion. She then hands it to him. When Buffy tells Spike coyly that Faith is still sleeping in her room, he is reluctant to have her stay downstairs with him since she kissed Angel, but gives in. Late at night, as Buffy and Spike are sleeping in each other's arms, the First appears to taunt Buffy in the form of Caleb, and then in the form of Buffy herself. Its words give Buffy a plan; when Spike wakes up, Buffy tells him that she now knows that they will win.
The next morning, Buffy unveils her plan to the Potential Slayers off-camera. Afterward, Willow expresses to Kennedy her concerns about using magic again. She says this is the most powerful magic she will have attempted and asks Kennedy to kill her if it turns bad. Faith and Principal Wood also have a discussion while preparing the school for the battle. Wood demonstrates that he understands her defensiveness over getting emotionally involved with men and asks her to give him a chance after the battle. During the night, Buffy goes to the basement, where she apparently spends her last night with Spike.
The next morning, everyone arrives at Sunnydale High in a yellow school bus. The Slayers and the Potentials head to the seal in the basement while Kennedy helps Willow set up her spell in Wood's office, Andrew is paired with Anya, Dawn leaves to set up her post with Xander, and Wood leaves to wait at his post for Giles. The core four share a moment talking about going to the mall after saving the world which causes Giles to say "the earth is definitely doomed." Xander and Willow walk down the hallway with Buffy before each one peels off, leaving Buffy walking alone to the seal. The Potentials, Faith and Spike are waiting, and the Potentials cut their hands to open the seal with their blood. They climb down the hole in the ground and come face to face with the army of Turok-Han. The Ubervamps spot Buffy, Faith and the Potentials, and attack.
Willow sits in the school principal's office directly above the Seal, the scythe before her. While chanting a spell, she places her hands on the scythe, and both she and the weapon light up in an ethereal glow and her hair turns white, the opposite of Dark Willow. A flashback to Buffy's final speech to the Potentials reveals that Willow is channeling the essence of the scythe in order to activate Potentials all over the world. Defying the tradition of only one slayer per generation, Willow's spell will raise an army strong enough to do battle with The First. After Willow performs the magic, Kennedy takes the scythe to Buffy, who is deep in the fight with Faith and Spike against the army of the Turok-Han, numbering in the thousands.
