The tears of relief, terror and anxiety gushed pricked at the back of Amy's eyes, before she released them, one by one at first, and then they came gushing, as if she'd removed a dam from blocking the tidal wave of distress. It came upon her with no warning, and there was no stopping it. The woman crouched down to where Amy had now fallen back and sat with The Doctor, but stayed away, not sure if she had in fact been bitten. The Doctor sat up and studied the woman, with short, grey hair, but kindly, warm face, full of life yet oddly drained. She wore a pink vest-top with a white cardigan over the top, jeans and trainers, but they were all covered in mud and blood. But before he could say anything, there were more footsteps. A confident, pressing stride. A sheriff's stride.
The woman turned around and stood to face the oncoming man, dressed in smart brown trousers and a yellow shirt: a sheriff's uniform. Upon his head perched a large, brown hat with a sheriff's crest on it, just covering his brow. He had a dark face, one of terror and nerves of steel. He had stubble, clearly having not shaved in a long while, which helped to disguise his true features. The Doctor and Amy could just hear the low voices, clearly American accents, and guessed that they were in America, but could not guess why both the man and woman's clothes were covered in blood.
"Why did you fire at them?! The bike was obviously too loud!" They could here the woman say.
"Excuse me, but this is not a matter for discussion. I'm in charge of this group, you know that. It's my call. They didn't answer, and now you've gone over there and butted in on something that doesn't concern you. Go back over, get in the car, and check on Lori. Leave those two to me."
The woman turned to gain one last look at The Doctor and Amy. She had stopped crying now and The Doctor had put an arm around her to comfort her, being careful not to get too close and give Amy the wrong message. Then, the woman stormed off like a scolded child, with heavy, forceful footsteps. The Sheriff then looked to them. He strode forward, and studied them carefully. He turned back and looked at the TARDIS. But someone was walking out of the trees. Slow, fractured steps, with his arms hanging in the air. His neck was tilted slightly to one side, but there was blood on his once white shirt, and his jeans were torn to shreds. As he came out onto the clearing of the road, the Sheriff strode over to him, knife in hand. With a loud crack followed by a long squelching din, the Sheriff thrust a knife into the man's head, straight through the eye, and slowly the man fell to the floor. The Sheriff coolly bent over, yanked the knife out of the man's eye and wiped blood off it with the dead man's shirt. Blood gushed from the man's eye similarly to the way tears gushed from Amy's eye just moments before. The Sheriff strode back over, and saw the shock on Amy and The Doctor's face. And surprise fell across his face. Like many things in the world, he did not understand.
