Buffy recognized the girl running down the street as Fred. The hospital had been cut off by too many of the undead and The City wasn't giving her an alternate route. There was something else that bothered Buffy. Signs of majordamage caused by more than just zombies. She needed to report back to Jesse and the others. The church was just in sight. The two of them could make it, they only had to make it a little further.
Buffy heard a noise from behind her from where she stood on the other end of the street. Before she could look over her shoulder, she held her sword like a javelin and threw it. It struck just a few feet ahead of Fred into the remaining bits of a still active zombie. All that had been left was a head, arm and bit of torso camouflaged by garbage, so soiled it blended in nearly perfectly with the street.
Then the slayer addressed the noise from behind only to find it wasn't one zombie but several. She marveled at how quiet they'd been. Spread more apart and with a little more time, she could have fought them safely unarmed. But the undead had gotten close and though she'd been able to fight them off, one of them managed to to take a bloody chunk of skin and flesh from her arm.
