Chapter: Diana

"I knew it!" the next few words don't bear repeating but he did raise an eyebrow at the colorful expletives. "Dammit, Sammy!"

Well, that got his attention.

"Hey!" he moves around the shack to get her attention. "Hello! Yeah," he nods once she turns towards him. "What the hell?" because he's not sure who she is, what happened, or how she even got there.

"I told her!" she kicks at the rickety table. "This time it's not my fault. I was right. I told her this Hunt was off, I told her it wasn't-."

"Told who?" he moves to block the door. "What the hell are you talking about and who the hell are you?"

She glares at him, a pair of dark green eyes narrow on him.

"Diana Campbell." She doesn't expect the surprise crossing his features.

"Campbell?" surprise quickly turns to anger and whatever the hell is going on is the Campbell's fault. That's what he's going with.

"Try and hold back on the animosity, Sparky." Diana doesn't hide the sarcastic anger. "Now who the fuck are you?"

He's annoyed by her demand. "Dean Winchester."

Diana feels as though she just got kicked in the stomach. "…Winch… Winchester?" she hates the sound of her voice- the sound of a lost little kid. "You're...? Your Father. His name." she gets up in his face and the lost little girl is now the angry young woman. "What's his name?!"

"Woa, woa-." Dean steps back from the angry female, hands up and ready to fend off any blows because she certainly looks ready to start scuffling.

"I'm not a God damn horse!" Diana shoves a hand at his chest. "Your Father's name!"

"I'm not above hitting a girl." Dean states, jaw clenching.

"Neither am I." Diana replies and the gray in her green eyes stands out. "So do I beat it out of you?"

Dean can't help the bark of laughter that escapes. She's ballsy alright and he's not sure where all the anger is coming from but it's got something to do with his Dad and that's never a good sign.

"John Winchester."

There's a long pause. Dean can see the hurt flashing across her face, the sting of tears in her eyes and the sharp inhalation of breath that she holds for a moment before exploding.

"That son of a bitch!" Diana turns, hands clenching in her loose hair.

"Hey-."

"He lied to me!" she kicks at the chair. "To all of us!" she turns on Dean.

"What?" Dean's incredulous disbelief is true and she knows it.

"He did have someone else." Because Dean is older than Adam and John had promised that had been the first time. "How long, huh?" she shoves at his shoulder. "How long was he cheating on Mom?"

"Who?" Dean's eyes narrow. "What the hell are you talking about?" he's pissed off too because now there's another one? A girl and obviously older than Adam.

"John Winchester." Diana spits past her clenched teeth. "That lying son of a bitch…" she steps away from Dean. "I'm gonna kill him." She starts moving around Dean to get to the door. She's been played for a fool and so has her Mother-

"Too late." Dean moves just a little and Diana turns to him once again. "He's bee dead 5 years."

"You're lying." Diana doesn't hesitate. "Sammy spoke to him three days ago."

"Now you're the liar." Dean scowls. "My Father is dead and how the hell-." He frowns as she pulls out her cell phone and ignores him. "What the hell are you doing?"

"What the fuck?" she can't connect her call and the operator is cut off mid-sentence.

"Problem?" Dean smirks still annoyed.

"For you." Diana glares at him trying to dial a different number. "When I put my boot up your ass."

Dean shakes his head and tries to modulate his voice to something sort of placating instead of condescending. "Listen sweetheart-."

"Gross." Diana cuts in. "Are you slow or just stupid?" she's looking at him likes he's grown a third eye and Dean has a moment of recognition. He's seen that exact expression before…

"You do realize we are related. John is- God I hate to acknowledge this- my Father as well as yours." She looks down at her phone and tries another number. "Dumb ass." Is the muttered insult she throws her 'brother'.

Dean decides to let it pass. He'll be the mature one. For once. And he's going to ignore the implication they share a parent. For the moment. "How do you know Sam?"

Diana doesn't bother looking up from her cell phone, still trying to get at least one of the contacts in her list to answer or at the very least connect. "She's my sister."

"Sister?" Dean echoes. "Sam?" he frowns; a little confused. She's not making sense. "What are you smoking?"

"Where the hell is this place?" Diana glares looking around the shack that isn't like the one she walked into with her sister. "Why can't I get anyone on the phone?"

Dean has enough.

"Where the hell is Sam?"

"Where the hell is Samantha?"

They look at each other, confusion clear on each face and the simultaneous question. They face each other.

"Who?" they echo in unison. Which is creepy either way you slice it.

"Alright." Dean has enough and he's not letting her out of his sight until he figures out what the hell is going on. "You." He jabs a finger at her. "Start from the beginning."

Diana shifts slightly. She seems to calm down, her arms slowly cross and the slight tilt of her head is a clear indication she's not pleased. It's eerie how Dean can tell her mood when he knows nothing about her but it's almost as though he's in her head in a way.

"Was that an order?" Diana's tone is deceptively serene. "I don't like orders." She points out, it's only fair since they just met. "Chris learned that real fast. You don't want to go the same road as Mark. So," she takes a step towards Dean. "Ask nice. … Brother."

Dean blinks. "Chris? Christian Campbell?" because that's not possible. The Campbell's are dead.

"Oh," Diana places her right hand on her chest. "Did I stutter?" she mocks, angry still. "Christian and Mark Campbell. My cousins-ugh," she rolls her eyes. "Guess they're yours too. In a way." She glares. "I don't have to share! So no, not yours."

"They're dead." Dean is harsh, the scowl on his face matching hers.

"And what the hell are you smoking, Dean?" Diana demands.

Dean ignores that and takes another step towards her but she's still not intimidated. "What the hell's going on?" he demands. "I want to know what you did with Sam?"

"So you're slow…" Diana nods like this is the answer she should've known all along. "Samantha," she states in her best 'I'm trying to dumb this down for you, idiot' tone. "K? and as far as I know you're working with that witchling." She jabs a finger at his chest. "You tell me what happened to my sister."

Dean scowls. "Listen, Sam, my brother-."

"Awesome." Diana rolls her eyes, hands moving to rest on her hips. "There's two of you."

So, just curious as to what you all think?
