He smelled her fear. That's what led him in the right direction. As he neared the woods where her stench came from, he began to hear sobbing. And smell blood…..
It took him ten minutes of running through this good sized forest, with each step he quickened his pace, hearing her sobs get louder. The smell of rear and blood mixed with the forest floor. The air was moist. It was so thick, he knew something had happened. Something terrible. Something terrible had happened to his Willow.
Finally, as he felt the awful stench now right upon him, in the distance, he saw a figure on the ground. He prayed it wouldn't be Willow, because as he slowly approached, he realized that she was naked. Her clothes ripped and sprawled around her, as if her quivering body were a shrine of triumph. Oz caught his breath when he saw the red hair.
As he came to realize this was indeed Willow, his world collapsed in on him. He ran to her now. She heard the approaching footsteps and rolled up into a fetal position as best as she could. She was kind of restricted by pain.
He knelt down next to once he finally reached her.
"Willow!" he cried quietly to show her it was him.
She was still crying as her head perked up in relief and humiliation. She couldn't meet his eyes, but when she did glance at him, she felt warmer somehow. Like this hadn't just happened to her. She said nothing, but when he hesitantly reached for her, she, as best she could, grabbed him close to her. He held her as she sobbed into his shirt, "Shh"-ing every now and then. Letting the tears fall freely from his eyes.
After a while, she seemed to have either fallen asleep or fallen unconscious, because she hadn't cried for a while. Though when he moved her a bit, he concluded that she was unconscious seeing as she didn't wake up.
Knowing they needed to get out of there, he acted as quickly as he could. He took off his jacket and gently wrapped it around her naked body. He slowly lifted her off the ground. The smell of blood was thick now. He carried her out of the forest, still deciding what to do. Should he call the police? Or go straight to Buffy? As he thought about it, he figured Buffy would be the one to go to. She needed to know about this as soon as possible.
He reached the van, thanking God no one else was around. And thanking God she was now safe in his arms.
She stirred a little bit as he gingerly laid her in the back. The smell of blood was less now, but he knew it was still on her legs. The final drops of the innocence stolen from her.
