She was wet. Something was wet. And her head was pounding and cars were buzzing all around her, what the hell was going on? Slowly she managed to get her heavy eyes open and sat up. She was literally laying in a gutter alongside the highway with an empty bottle of booze gripped tightly in her hand.

"What the hell?" she groaned to herself, rubbing her pounding head. Quickly she checked over her body, she was soaking wet but fully clothed and no new injuries to report. Then she took in her surrounding and recognized where she was. The bar she had went to with Kevin a year ago was right across the street.

She wondered to herself how she got here, because the last thing that she remembered was telling Sam goodbye before he went off of his hunt. Had she gotten that drunk after he left that she didn't even remember getting drunk? Apparently so, and whatever she didn't remember drinking last night was not sitting well and she found herself on all fours vomiting violently into the muddy gutter. When she was done she wiped her mouth on her shirt and slowly got out of the gutter, wiping the mud off of her and started trudging back to the bunker. It was cold and slippery from the melting snow so she was glad to get back inside the bunker and strip down. She tossed her clothes on the floor of her bedroom and then walked through the bunker to the bathroom.

However she was walking by the map table when someone else walked through at the same time. Quickly Imogen grabbed the spare gun they kept hidden and pointed it at the stranger woman.

"Who the hell are you?" she yelled, not caring that she was completely naked.

The woman's eyes went wide and she dropped her bowl of cereal, it shattering and making a mess when it hit the ground, and pulling out her own gun to point at Imogen, "Who the hell are you?" she demanded louder, "And why the hell are you naked?"

Imogen didn't flinch, "I'm not the one intruding in someone else's home, so you better explain who the fuck you are before I shoot."

She crinkled her brow, "Your home?" she questioned, "Wait… Are you Sam's girl? I didn't know he was seeing anyone. Makes sense though, I mean why else would you be naked here in the bunker with him?" she laughed uncomfortably.

"No I'm not Sam's girl," she spat angrily, "Who the hell told you that you could be here?"

"Dean did," and then the woman froze, "Oh god. If you're not Sam's girl that must mean you're with Dean," she shook her head, lowering her gun, "That son of a bitch. And here I was thinking I finally found a good guy."

Imogen still didn't take her gun off of her, "Who. The. Fuck. Are. You?"

"I'm Kristen," she stated, "Dean and I were kind of… well whatever hunters are when they're sleeping together. I can't believe he told me I could hide out here when he knew you were here," she sighed softly, "Where's Sam?"

Imogen shook her head, "No, I'm not buying it. Dean doesn't bring girls home."

Kristen looked at Imogen, "Are you gonna shoot me?" she asked, "If not could you take the gun off of me? Look, I'm sorry if he was your boyfriend first, I didn't mean to get in the way. He really did tell me I could crash here."

Hesitantly Imogen lowered the gun, "You got a phone?" she asked.

Kristen nodded.

"Dial Dean. I wanna hear this from him."

"Absolutely," she dialed Dean's number and put him on speaker when he answered, "Hey, Dean."

"Hey, Kris. I meant to call you."

"Uh yeah, why'd you tell me I could hang here with your other girlfriend?"

"Gross, she's not my girlfriend. I thought Sam was gonna be there when you got there, but turns out we ran into each other on this hunt. Lemme talk to her," slowly Kristen walked across the room and handed Imogen the phone.

"Dean."

"Hey, Em. I'm sorry. Look, Kristen is cool. She'll stay out of your way. I'll explain everything when I can. Just don't shoot her, all right? I'll be back there just as soon as I finish up this case."

"Fine," Imogen grunted as she hung up the phone and looked back to Kristen, "I'm Imogen," she held her hand out to offer to shake.

Kristen took her hand and shook it before letting go, "Mind if I ask why you're naked?"

"Was going to take a shower… Thought I was here alone."

Kristen nodded, "Mind if I ask who you are?"

"Imogen," she repeated, "Thought I already said that."

"No, I meant how do you know Sam and Dean?"

"Oh," Imogen nodded slowly, "I'm their sister."

"I didn't know they had a sister," she said, shocked.

"Yeah, we'll they kept me locked in the basement for the first twenty or so years of my life. Not many people knew about me," Imogen stated seriously.

Kristen looked shocked.

"I'm kidding," she said, "I'm a little cold, so I'm gonna go and take that shower," slowly she walked away and got in the shower, turning up the heat as hot as it would go and letting it sting her skin as she tried to wash away the idea of her brother having a girlfriend.

Imogen would have showered longer but the water turned cold and she got out, wrapping a towel around her and opened the door, but once the cooler air from the bunker hit her she found herself once again on her hands and knees now dry heaving into the toilet because of her hangover. When she regained control over herself she brushed her teeth and walked back to her room to get dressed. She wrapped her long hair up in a towel and then went in search of food, however she ran directly in to Kristen.

"Oh, hey," Kristen half smiled, taking a sip from her beer, "Hope you don't mind, Dean told me to make myself at home."

Imogen nodded wearily, "It's fine. Have all the beer you want."

"Look, Imogen. I'm sorry. I didn't mean to just barge in and put all of this on you. If I had known you were going to be here all by yourself, not knowing anything about me, I swear I wouldn't have shown up. But like I told you, he told me to come. He thought Sam was here and-"

Imogen put a hand up, "Look, Kristen-"

"Please, call me Kris."

With a roll of her eyes Imogen continued, "Okay, Kris. I really don't need to hear your explanation. Dean said you could be here, then you can be here. This isn't my home anyways. Dean and Sam get to say who stays and who goes," she walked passed her and towards the kitchen, slightly annoyed when she followed.

"So, how come they never told me that they had a sister?" she asked innocently, "I mean, I've known these boys seven or eight years now and they never once mentioned a sister."

"I don't know," Imogen grunted, opening up the fridge and taking out a box of Hot Pockets, "Maybe Dean doesn't trust you," she stuffed them in their sleeves and put them in the microwave to cook.

"Oh," Kristen nodded, "Maybe… But you look a hell of a lot younger than Sam or Dean."

"Same father, different mothers," she muttered, staring into the microwave as the Hot Pockets spun round and round.

"Oh okay, now I get it."

Slowly Imogen turned to face Kristen, "What do you get?"

"Well, why they never told me about you," she paused, "I mean, you're not really their sister."

This was going to be good, "Really?" she began, "That's funny. I thought I was."

"I mean half isn't full. Like with Adam. Sam and Dean are full blood brothers. They'll always look out for each other before anyone else. So you'll fall in line somewhere after that," she nodded, "No offense, but if you really were important to Dean or Sam one of them would have mentioned you somewhere down the line."

"Wow," Imogen couldn't believe the ugly words that had just come out of that beautiful woman's mouth, "First of all, Sam and Dean raised me since I was barely out of diapers. So I'm pretty comfortable saying they're looking out for me just as much as they are each other. Second, you can go and shove you self-conscious bullshit up your lily-white ass, because you're not going to try and take me down to feel better about yourself. And third, I don't have to explain myself to a cheap piece of ass that I'm sure my brother's gonna shove off the second he finds someone better," the microwave beeped and she turned to get the plate, "Stay outta my way and we won't have a problem," Imogen barked as she walked passed Kristen and headed to her own room.

It was a little while later when Imogen was kicked back, enjoying some TV, when she heard a soft knock at the door. She wanted to ignore it. Wanted the girl on the other side to go away, but instead she groaned and rolled out of the bed and slowly walked over to open the door.

"What?" Imogen grunted.

"Look, Imogen. I'm sorry about what I said. I get… Well, kind of jealous. I'm a little psycho," she admitted.

"Oh great, my brother really knows how to pick him a winner."

Kristen nodded and looked down at her feet, took a breath, and looked back up, "You have every right to hate me after what I said. It just messes me up a little that I've known Sam and Dean this long and neither one has ever mentioned you. I mean, they are Sam and Dean. They're brothers. Family is a huge part of who they are, so when you told me that you were their sister… Well, I kinda felt like Dean had been lying to me all of these years."

"Listen, Kris. Dean, Sam, and Me we were all a team for a while. I didn't leave their side. I was hunting with them by the time I was a teen and it was great. We were inseparable. But I fucked up. I'm not gonna go into what happened there, but I did. I was outta the picture for years. I've only recently come back into their lives."

"You were dead, weren't you?" Kristen inferred.

Imogen chuckled, "No, I wasn't dead. But Sam and Dean thought that I was up until about a year ago. For the last year I've been hunting with Castiel. You know him?"

"I know of him," she nodded, "Dean's told me about him."

"Okay," Imogen nodded, "It's not your fault they didn't tell you about me. It's mine. They're kind of ashamed of me."

Kristen nodded, "I really am sorry for lashing out at you like that. It was stupid. I'm kind of stupid sometimes."

Imogen shook her head, "Nah, if you were stupid Dean would've just screwed you and left," she sighed, "How did you meet my brother?"

"It's a long story actually," she paused, "Do you wanna hear it?"

"I guess," Imogen walked over and sat back on the bed, "Sit anywhere."

Kristen nodded and took a seat at the edge of the bed, "Well, I was working a case that he just so happened to be on. He, being Dean, told me to buzz off and that I was just going to get in his way. Me, being me, told him to stick it where the sun don't shine and I went on with my hunting. By the end of it we had both saved each other's asses countless times. We kept in touch after that, worked a couple more cases, and then it became more than just an occasional hunt. I mean, don't get me wrong. He still does his own thing most of the time and I still do mine, but we come together every few weeks or months and hang out."

"So you're not like exclusive?"

Kristen shook her head, "Like I said, he does his thing and I do mine. Dean can't be tamed, and well- neither can I."

"Why the fuck did you freak the hell out on me?"

"Just because he's not mine doesn't mean I wanna know about the other women in his life."

"But I'm his sister."

"Right," she nodded, "Sibling commitment probably means more to Dean than anything I'll ever get outta him. Like I said, I'm a little crazy."

"You can say that again," Imogen nodded.

Kristen sat there awkwardly for a few minutes, "So, do you wanna go out for a drink tonight?"

"Oh no thanks," Imogen turned down the offer without hesitation, "I drank so much last night that today has been hangover hell."

Kristen nodded, "I thought I heard you throwing up. I didn't wanna invade your privacy though."

That made Imogen actually laugh out loud, "Oh sure, the first interaction we ever had I was completely naked but you didn't want to invade my privacy."

A small smile tugged at Kristen's lips, "I give you credit girl, you're not ashamed of what you look like."

Imogen shook her head, "No I'm not. And hell, why should I be?" she grabbed her bottle of water off her bedside table and took a sip, "Dean's gonna love this story, I tell you what."

"He'll definitely get a kick out of it," she agreed.

"Listen, Kris. I'm probably about to try and get some sleep. I feel like I got hit by a truck. If the guys show up would you wake me up or have one of them do it?"

"You got it," Kristen nodded, getting up off the bed, "Sleep well," she said, walking out of the room and shutting the door behind her.

Imogen breathed a sigh of relief when Kristen was gone, "What a crazy bitch," she whispered to herself as she turned over and fell asleep.
