Buffy/Faith
Faith happened to be glancing over when she saw Glory cut B with the sword. Anger stirred inside her. No way. No FUCKING way. Her eyes narrowed, and she began to fight her way over to reach B. She got there just in time to see her kill the guy, Ben, who apparently had been Glory-which still confused her just a bit. She was distracted for a moment, and didn't turn towards B until after she'd fallen to the ground.
For a few precious seconds, she stood there, between the guy B had just killed and B, who now had a wound so similar to the one she'd given Faith. She wanted to walk away. Really, she did. But she didn't. Instead, she pulled off her leather jacket and balled it up as she dropped to her knees next to the blond. She pressed the jacket tightly against B's stomach even as her dark eyes glanced around to see if anyone else had seen what had happened, and who could come help.
If B was lucky, it wouldn't be too deep and it might even begin to heal quickly so that she'd be able to be moved soon. She wasn't gonna let Buffy die, not now anyway.
