Glory is a hell god, and she is tired of sharing a body with a mortal. Upon gaining the knowledge that the slayer’s sister is the key she’s been looking for, she prepares to preform a ritual. Using the key’s blood, Glory plans to open a portal, sending her back to her home dimension. Not only that, but upon opening the portal, the boundaries between the dimensions will dissolve and destroy the universe. Her only weakness lies in her bodies true owner, a male nurse called Ben. Catch Ben when he is in control of the body, kill him, and Glory will be destroyed. The only problem is Glory’s power makes any mortal forget the fact that Ben and Glory share a body every time this vital information is revealed to them. Every mortal except the key, Dawn. That’s not Glory’s only problem. Ben is gaining more control over his body, so Glory strikes up a deal. Ben helps her kill the key, and she’ll make him immortal. So Ben takes Dawn and hands her to Glory’s minions. The slayer’s watcher, Giles, then reveals that once the ritual begins, the only way to stop it is to kill Dawn, or so they thought. Despite the Scooby Gang’s efforts, Dawn ends up tied-up at the top of a tower, the ritual already begun. Buffy, the slayer, fights to get to the top of the tower. When she does, she explains to Dawn that because they are sisters, they share the same blood. Therefore, if Buffy jumps into the portal, she will be sacrificed, in turn closing the portal. Just as she is about to jump, Buffy hears a noise. Looking up, a blue police box appears. The door opens to reveal a man and a redhead woman, who effectively shut down the portal. On the ground below, the vampire Spike uses his knowledge that Ben is Glory to kill the male nurse, in turn killing the hell god Glory. The portal may be gone, and the hell god dead, but who is the mysterious man and woman who saved the day? And what on earth is that blue box?
“Dawn, listen to me. Listen. I love you. I will always love you. This is the work that I have to do. Tell Giles… tell Giles I figured it out. And I’m okay. And give my love to my friends. You have to take care of them now. You have to take care of each other. You have to be strong. Dawn, the hardest thing in this world is to live in it. Be brave. Live. For me.”
