A/N: Now is when the "T" rating really takes effect. I like to curse a lot, so be warned...and I apologize for another short chapter. I know it's getting boring, but this is the first fanfiction I've written that I'm actually trying to completely finish, so just bear with me. I'm also going to include a real description of Rose and her backstory in a later chapter-possibly within the next two chapters.

Chapter 4

The next evening

"I really wish she would've let us help her..." Sam makes a face and adjusts his position, the vinyl upholstery making noises as he moves.

"It'll be herfault if she gets hurt, Sammy." Dean sighs and keeps a lookout for any sign of Rose in front of the abandoned factory. "But I still get what you're feelin'. She's probably gonna go in and fight some vampire in there and if she gets in trouble-"

"-That's why we're out here; yeah..."

"I bet she'll be fine," Dean says, and several minutes of silence follow. There is the occasional chirp of a cricket or low whisper of the warm wind, but other than that...nothing.

Until there is a sudden echo of a chain-link fence as someone climbs over it. Both brothers' eyes shoot up toward the factory and see a tall feminine figure give them a small salute before jogging up to the back door, where a silo blocks the Winchester's view. Sam immediately gets out, leaving his brother in the car saying, "I thought we were stayin' in the car."

"What I said was we'd keep an eye on 'er, Dean."

"Fine-"

Within moments the two were climbing the fence and following a trail of doors with broken padlocks until they hear the echoes of people fighting. Dean seizes Sam's shoulder and drags him against a doorframe, then dives to the opposite side. "What're you doing?" Sam whispers harshly.

"Rose doesn't know we're here, moron! Whaddya think she'll do if she finds us?"

Sam keeps his mouth shut and they both peer out to see how Rose's fight is going-

"GAH!" Rose bellows as the fang catches her in tight grip, but she stomps her heel down onto his toes and as he recoils she snaps her head backward into his nose to escape. "I'm gonna kill you, you little bitch-" He swings his fist toward her, but she blocks him and curls her arm around his, bending it the wrong way. "AH!" He shouts, trying to slash at her with his other hand.

Rose ducks and kicks his chest, pulling a small wooden stake out of her jacket as he staggers backward. She then swings it quickly in front of the fang's face like it's a stiletto.

Sam whispers, "What's she-"

"She's distractin' 'em." Dean smiles giddily.

A loud, gurgled "Argh!" catches their attention once more, and they both glance back just in time to see Rose draw a machete from her belt and slice her opponent's head off, which causes both Winchesters to shout, "Holy shit!"

Rose spins around to face them, blood dripping off the blade of her machete and the stake poking out of the vampire's chest. "What the fuckare you two doing here?!"

"We wanted to...eh..." Sam steps out from the doorway with Dean following close behind. Rose holds the huge blade out between them. "I thought I told you two to leave town," she says firmly, glaring up at them.

Sam starts, "Um-"

"My brother's about to say that we were gonna leave, but we heard a struggle in here, so we thought we'd check it out."

She stays silent for a moment...then lowers the machete, flicking some blood onto the vampire's corpse. "Fair enough...now just...go. Go while I'm still in a decent mood." She glances down and steps away from the rapidly growing puddle of blood. She mutters, "What a waste..."

"Were you questioning him?" Sam looks at her in disbelief.

She sighs. "...I'll tell you somewhere else. I think the nearby neighborhood might've heard all this and I'm not in the mood to deal with cops," she continues, pulling her stake out of the vampire's heart and leading them all out.
