A Gift
It was the evening of Tara's funeral and Cordelia noticed that Willow was shaking with sobs. I've never seen Willow so unhappy before; there must be something I can do to cheer her up.
"Willow, are you all right?"
Willow glared at her, and for a moment her eyes went all black. "What do you think? Tara was everything to me, everything. She was the light of my life. I feel broken inside." Willow pulled a silver necklace from her pocket with an amber heart on it. "She told me once that if she was ever to die before you, then you were to have this as a gift from her."
"That was nice of her." Cordelia put on the necklace and Willow leaned in and hugged her tightly. She whispered softly in her ear "Tara..."
This is not good. "Willow, you're starting to freak me out now, I know how you feel, it must be horrible to lose Tara like that, gunned down in your arms, but I'm not Tara and you know I'm not her. I can't be your substitute Tara, I'm straight..."
Willow cut her off with a big warm kiss on her lips, gripping her wrists hard and pinning them to her sides. Cordelia pulled away and got a glimpse in the mirror, and reflected in the mirror was Tara, with her blue eyes and dirty blonde hair, smiling at her. Cordelia opened her mouth to scream but the scream died in her throat. She tried to reach up and wipe her mouth but her hands moved around Willow's waist instead.
"You must wonder what is happening to you. Well," explained Willow, "we all know that Sunnydale is a dangerous place, with vampires, demons, and other assorted nasties around. So we cast a spell to ensure that if Tara died her soul would be sent to the amber heart you are wearing as a phylactery. Then she could possess whoever wore it. Buffy and Faith are Slayers and might be able to break free, Dawn is too young, and Xander is a guy and I am not making love to a guy. The illusion spell I cast only makes you look and sound like Tara to you and of course to me."
"I'm going to enjoy living a long life in your body," Cordelia heard her new voice say, and screamed soundlessly inside the prison that her body had become.
