Willow and the others perform the spell at her grave, oblivious to the fact that it no longer remains six feet under, but in a spiritual realm, fighting its way back.
..................................
Buffy, with her body, was fighting. The guardians were trying to hold her in heaven, where she had ascended past her death.
But she didn't care right now. All she wanted was him.
It didn't matter that he was a vampire, or that he couldn't go into the sun.
They would make it work. And if he still had doubts, she would set him straight, and go from there.
It hurt to fight now, after months of straight fighting for her life, and her freedom from heaven, her way to Angel, she was weakening. These guys were tough, and there were over three of them.
But she knew that she was stronger and better. And even if she wasn't... well, love makes you do the wacky. She would beat them anyway.
When she was hit back again, she landed on her knees.
"Always." She whispered to eternity, and she got back to fighting her way home.
