Meg instinctively threw her power up to defend herself, but not fast enough. The knife in Jo's right hand came swinging towards her face, opening a long, deep gash along one cheek, spilling a thick red stream of blood down her neck. An inch or so higher and it might have taken out her eye. The knife in the girl's left hand, however...well. If she'd been anything but a demon, that probably would have been the end. It slammed into her stomach with enough force to drive her back against the brick wall behind her and force the air from her lungs in a strangled gasp. For a moment, she panicked. Once again, she could feel Crowley's blade sliding into her, setting her on fire from the inside out, ending everything. Instinctively, she threw here power at Jo, pushing the girl away forcefully.
The knife was still buried in her stomach, up to the hilt in the flesh of her meat suit. She reached down and drew it out, slowly, grunting in pain as she did so. Blood dripped onto the concrete. She looked at Jo, her eyes fading back to normal, and contemplated what to do to her. But it wasn't that easy, was it? She thought of Sam, and the promise she'd made. He'd left her high and dry, but she was a woman of her word, and always had been, even if they didn't see it.
Slowly, deliberately, Meg tossed the knife at Jo's feet. She held her hands open at her sides, a look of resignation on her face.
