Red was laying on the couch, soaking the cushion with each light breath. Nothing was happening yet, just the slow creaking of the floorboards as Dean paced them. Reds hand was laying on top of her stomach letting Dean and Sam have a full view of it.

Dean exhaled heavily, looking at the calm freckled face. He couldn't tell what was going on in that mind but he knew it wasn't something he'd approve of.

Reds blue eyes popped open. She sat up, hair leaking blood. She twisted her head violently pulling back each strand of red hair.

"Not know Gen." Dean growled he glanced into her crimson eyes, but he continued to pace.

"Aw, but why not?" Gen teased pushing her self up to a standing position. She pulled up the mangled hand ready to pull back her hair. "Holy! What the hell did you do to my hand?"

"It's Red's hand. Not yours." Sam told her, fingers making swift stokes on the laptop.

Gen glanced around and her cherry eyes widened. "Why is there a pack of black wolves outside?"

"Wait. You can see them?" Dean asked momentarily stopping his pacing to glance out the window.

"Obviously. They're the most feared creature in Hell. To catch and tame one, basically asking for a death wish." Gen told them walking over to Sam, every step caused the floorboards to creak violently.

Sam looked up at Gen who was right on top of him at the moment. She pulled her normal hand across his neck, causing him to start spitting up blood.

"Oh calm down." Gen told Deans startled remark. "I didn't kill him."

"Yeah." Dean grumbled walking over to his brother, placing one hand on his shoulder.

"So. The black wolves had a taste for red meat last night?" Gen asked, stretching out her fingers.

"Yes." Sam choked out, spewing blood all over to table.

Gen screamed in agony as she pulled away from Red. Red stumbled back into the chair falling into it. She gave them a pleading look, then cupped her mouth to keep herself from screaming.

Her hands wounds were creeping up her arm, stopping at the elbow. In it's tracks it left burnt skin, open cuts and skin peeling back trying to get away from the infection.

"It's moving faster." Dean said grimly, placing a hand on Sam who had stopped choking.

"Yep." Sam grumbled pushing a finger on the laptop, clearing all searched.

Sam was up for three nights strait, trying to find a cure. Luckily the wolf bite hadn't spread any further, but didn't allow Red to do the slightest things.

Em and Cas hadn't been helpful, most of the time staying upstairs, watching old movies. Dean could've swore he saw them making out at one point, but probably not.

"Dean!" Sam called from downstairs. A tired Dean came down, his eyes blood-shot. "Listen to this."

'The Mark of the Black Wolf is highly contagious, touching, eating, or drinking anything the victim has had contact with in the last twenty four hours can infect another human. The Mark can take days to months to be put in full effect, it depends on how hard the person is fighting it. All known victims have died.'

"That's supposed to make me feel better how?!" Dean screamed hitting the wall next to him.

"It was just-" Sam started but was cut off by a large scream coming from upstairs. Both boys quickly turned around to hundreds of footsteps and worst of all...

There was blood pouring down the stairs.

A/N Yeah. I thought I needed to put a little more info on the Mark of the Black Wolf in case anyone else would like to use it. If so, help yourself! It's an amazing plot, you'll just have to see how to get rid of it, well if you can. -Panda <3
