Chapter 1- We Need A Doctor
Sounds of gunshots bounced off the walls of the cave, followed by inhuman screams. Dean was firing his pistol at the creature. What the hell is this thing? It had the upper body of a woman and the rest of her was like a spider. Spikes protruded from her thin, gray skin and long, dark, filthy hair lightly covered her breasts. "You okay there, Sam?" Dean called out, dodging one of her eight legs. Sam was pulling gobs of warm silk from himself, "Yeah, fine!" He answered. Dean looked back at the spider woman in time to see one of her legs before he flew into the cavern wall. He caught her wrists as her hands clawed at his face. He could see venom dripping down her fangs by the light of the poorly lit lanterns they brought. There were no electrical lighting in the caverns in 1860. They had chased this thing from the present to roughly 150 years into the past, with Cas' help. "Sorry, sweetie," He smirked, "You're just not my type." She answered by screaming in his face, "You don't get boyfriends by screaming at us."
She suddenly pulled back, shrieking and reaching at her back. Castiel had stabbed her in the back with his angel blade, though it didn't penetrate deep enough to prove fatal. He fought for balance as the spider woman bucked, trying to throw him off. She succeeded finally, slamming Cas into the wall. The angel slid down the rock, immediately positioning himself with his blade. Dean picked up the gun he had dropped and ran to help Castiel. She gave a frustrated screech as she turned to Dean and shot her web at him, sticking his arms to his sides and his legs together. Castiel was in between them in no time, with his angel blade ready. She swung her front legs at him. He brought up his blade in defense, only to have it easily knocked away. He watched as his blade fell to the ground with a clatter. Cas, now disarmed, looked up at the spider lady who was now towering over him. The blade didn't fall that far away. He could retrieve it in time. He carefully watched her movements. The way she swayed from side to side to easily pounce on her prey should it foolishly choose to escape. He only waited as she crept closer. Waiting for the right moment. She raised to her full height, ready to strike.
He waited.
She held her pose there, making sure to attack when he lowered his guard. Castiel stood his ground, fully aware of everything around him. Looking for a slight movement. Moments passed. Time moved slowly for the angel with his senses being in overdrive. He saw that flicker.
He crouched, pulling his leg muscles taut and sprung away from her assault, the stone exploding into debris and dust where he had stood a second earlier. He quickly grabbed his blade and turned to face his opponent once again before he found himself caught by his throat in her grip and held against the wall. Before he had time to react, she clamped her jaws around his left shoulder, biting into him. He let out a strangled cry as pain overwhelmed his nerves. He began to feel light headed, hearing the muffled sound of Dean shouting his name. He gripped the blade tight in his hand, and plunged it into whatever happened to be there.
Cas felt himself hit the ground as he heard the spider lady scream in agony. Her hands went to her middle. His blade was buried up to the hilt in her body. She hissing strained breaths, red eyes filled with hatred as she stumbled away into the darkness.
"...sti...el...ca...s... Cas!" Dean's voice echoed through the cave and cut through the blackness that Castiel had tried to push away. The angel had exhausted most of his grace bringing them back in time, there's hardly any left to heal himself. He cried out when a sharp pain exploded in his shoulder when he tried to move.
"Cas! Are you okay!" Castiel felt his shirt being ripped apart and his suit jacket and trench coat being moved away. He slowly opened his eyes to see Dean examining the wound on his shoulder. "Jesus..." Dean muttered under his breath. The gash was really deep and bleeding heavily. Once pale skin, started glowing bright red and became sweaty with fever as the venom spread though his veins like wildfire. Cas knew that thing would return soon, and they are not ready for a second round.
Sam pulled a clean rag out of his bag and pressed it against Cas's shoulder, trying to stem the bleeding. A low growl reverberated through the cave, making them all look around nervously. "We need to get out of here." Sam said quietly. Dean nodded in agreement. "We need a doctor, too." He added. The lanterns flickered dimly as another bestial sound made the very stone shiver. Cas flinched under Sam's grip, and struggled to reach out to the brothers.
"Don't move, Cas, you're going to make it worse." Dean said as he pushed his arms down. He pulled out his pistol as he stood up, taking another look into the darkness. "Sam, I want you to take Cas and go. I'll deal with this bitch." Sam looked up at his older brother, "Dean, no—"
A sudden shriek and scuttling sounds echoed around them, making them jump. Castiel took the distraction as an opportunity and pushed himself to his feet and placed each hand on their shoulders, and with a sound of beating wings, they were gone.
