Chapter 1.
Season 4 Episode 19.

The ringing of a phone makes Dean and Sam pause their conversation as Dean pats his self down for the phone. He leans through the Impalas window and rummages through the glove compartment, grabbing the source of the ringing.

"Isn't that dad's phone?" Sam says, as Dean nods his head and answers the call.

"Hello?" he says leaning against the Impala.

"Uh, is this John?" a young mans voice come through the phone.

"He can't come to the phone. Can I help you?"

"No...I really...I need to talk to John. This is Adam Milligan. He knows me".

Dean lets out a sigh, "Well, sorry to be the one to break this to you, pal, but John died more then two years ago".

There's a slight pause from both ends as Sam and Dean turn and look at each other, before Dean decides to talk again.

"Who is this?"

The words that come from the phone make Dean freeze, "I'm his son".

Windom, Minnesota. Milligan House.

Dean stops and picks up a picture of Adam and John.

He looks up at Adam with disbelief and hurt, "He took you to a baseball game?"

"Yeah, when I turned 14. Dad was around for a few of my birthdays" Adam smiled.

Sam turns to Dean with the journal and turns a couple of pages, "September 29th 2004. One word. Minnesota".

Dean stumbles with his words till he bites out, "He took you to a freakin baseball game?"

"Yeah".

Dean narrows his eyes slightly as Adam takes the picture back.

"What'd dad with you on your birthday?" Adam asks.

Dean turns to Sam with wide eyes, and he decides to change the subject.

"Adam, you said you called dad because your mom is missing" asks Sam.

"Yeah".

"How long has she been gone?"

"3 days".

Dean slightly shakes his head to get his mind back on topic, "who was the last person to see her?"

"Mr. Abbinanti, our neighbor. He saw her come home Tuesday evening, but she never showed up for work on Wednesday.

Dean looks past Adam, and see a picture of John and Kate. He sighs and looks at the ground

"Did you call the police?" Sam asks

"Mom's supervisor at the hospital did. And then i drove down here as fast as i could", Adam pauses and swallows, "I should have been here".

Breaking the awkward pause Dean continues, "What'd the, uh, what'd the cops say?"

"They search the house. They didn't find anything...She wouldn't leave without telling me. It'd like she just dropped of the face of the earth, you know?" he sucks in a breath, as he trys not to cry.

"Can you show us your moms room" Sam asks.

"Errr, sure" confusion lacing Adams voice.

They start following Adam out the room when he stops and turns to them.

"Uh, I just had a thought. If dad didn't tell you about me, I'm guessing he didn't tell you about Emily".

Both brothers pause in their steps and look at each other. Sam in confusion and Dean in disbelief and annoyance.

Dean mutters, "This better not be going where I think this is going".

Sam take a small step, "Emily?"

"My sister...Well, I guess now she's your sister too".

There's a short silence before Dean explodes, throwing his hands in the air, "Oh for-"

Sam cuts Dean off, "Sister? Dad told you that we have a sister".

Sam pays no attention to Dean as he glares at him, instead he looks at Adam.

"Yeah ,uh, Emily Draper. She lives in Wisconsin...errrrr Janesville, Wisconsin, I think. She's like 14 years old. I actually met her once, dad brought her here for one of his visits. We email every now and then" Adam shoves his hands in his pocket, "I should probably call her or something and tell her about dad and about you guys".

"Great!" Dean gives a big sarcastically fake smile to Adam, before giving it to Sam, "Just great!"

Dean lets out a frustrated sigh before rubbing his face.

"Lets just find out what happened to your mom first, before you tell us about other brothers and sisters we have okay" Dean finished with his bitch face.

Adam shifts his feet, and looks uncomfortable "Um, as far as I know it's just Emily".

"Just show us to your mom's room" Dean huffs.

"You sure we should do this?" Sam asks looking at Adam's body wrapped in sheets. Dean grabs the bottle of lighter fluid for him.

"Ghouls didn't fake those pictures. They didn't fake dad's journal", he pours the lighter fluid over the body, "Adam was our brother. He died like a hunter. He deserves to go out like one".

"Maybe we can bring him back. Get a hold of Cas, call in a favor".

Dean gives Sam a look, "No, Adam's in a better place"

He lights a match and drops it on to Adam's body. Both brothers watch the flames rise.

Letting out a breathe Sam asks, "What are we going to do about Emily?"

Without missing a beat Dean responds, "Nothing".

"Dean-"

"No Sam!" Dean gives Sam a look between annoyed and angry. "Look what happened to Adam. She is safest far away from this life. Away from us".

Sam looks at Dean with his bitch face, "Yeah, cuz that did Adam any good. She's a Winchester and just like Adam, if any of the many supernatural creatures out there find out she's a Winchester, they will kill her. They will kill her slowly and painfully just because of me and you and dad. But, if she's with us, we can train her and keep her safe".

"Sam-"

"No Dean, you say Emily is safer away from us. But the truth is, she's safe with us. On her own shes vulnerable, an easy target... Then, she really will end up like Adam" Sam shakes his head, "Why are you so reluctant about this. You were reluctant about Adam, now Emily. You've said it yourself, family is important. So why are you being like this? Are you jealous?"

"No, I'm keeping her safe, like dad would have wanted".

"Dean!"

"We leave her alone, end of discussion" Dean gives Sam a final look, before watching Adam's burning body.

Season 5 Episode 18 (The ending).

Dean is driving the Impala with Sam sitting next to him, neither brother having said anything since Zachariah's death and losing Adam again.

Sam lets out a sigh, "You think Adam's okay?"

Dean glances at him, "Doubt it. Cas either. But we'll get them".

"So..."

Dean looks at Sam briefly when he doesn't continue, "So what?"

"I saw your eyes" Sam looks at him, "you were totally rockin' the 'yes' back there...So, what changed your mind?"

Dean gives Sam a quick look, "Honestly? The damnedest thing. I mean, the world's ending. The walls are coming down on us, and I look over to you and all I can think about is, 'this stupid son of a bitch brought me here'. I just didn't want to let you down".

"You didn't. You almost did. But you didn't".

"I owe you an apology"

"No, man. No, you don't" Sam shakes his head.

"Just...let me say this. I don't know if it's being a big brother or what, but to me, you've always been this snot-nosed kid that i've had to keep on the straight and narrow. I think we both know that's not you anymore. I mean, hell, if you're grown-up enough to find faith in me...the least I can do is return the favor. So screw destiny, right in the face. I say we take the fight to them, and do it our way".

"Sounds good"

Sioux Falls, South Dakota. Bobby's House.

Sam and Dean are sat around the table. Dean drink a beer, while Sam is helping Bobby with research. Dean rubs his face and puts his beer down, then looks at Sam.

"What?"

Sam looks up confused, "Huh?"

"Your making a face, a 'I-have-an-idea-but-your-not-gonna-like-it' face. So what is it"

Sam sighs and shuts his laptop, "It's not an idea, more of a thought".

"Get on with it".

Sam looks at Bobby, then back to Dean. Sighing again Sam says, "Emily-"

"No" Deans says without hesitation.

"Dean-"

"No Sam. We've been through this. We stay away from her".

"Excuse me for interrupting this conversation, but just who is 'Emily'" Bobby asks.

Neither Sam or Dean say anything or look at him. Bobby sighs before landing his gaze on Dean.

"Crap" Dean mutters.

"Well".

Sighing Dean looks at the kitchen wall, "Emily is our sister".

Bobby looks between the brothers, before shaking his head, "Idjts".

"Hey, it was dad that knock up some woman. Not me" Dean says.

"Yeah, but you knew and didn't think that telling me was important? Especially when we have the end of the world coming right up our asses, with Demons and Angels all wanting a Winchester meat suit!", Bobby stands up, "You also want to explain why you told me about Adam but forgot to inform me about this other Winchester?"

"Well, once we told you about Adam and found out that you didn't know about him. We figured that you wouldn't know about Emily, so I saw no point in bringing her up" Dean says

"You're a complete idjt".

"But Bobby makes the point that I was thinking" Sam says, "The Angels went so far as bringing Adam back from the dead and brainwashing him, just to try and make you say yes. What will they do to Emily? Or if the Demons get wind of her. I've said it before and i'll say it again. She will be safer with us".

"No Sam-"Dean growls.

"Your brothers got a point Dean" Bobby sighs, "Yer dad kept her and Adam a secret to protect them, but Adam's dead and being used like a pawn. You wanna keep this girl safe? Keep her by your side".

Dean lets out an angry huff of air, "Fine! You win. We'll go and ruin this girls life".

Sam rolls his eyes and opens his laptop, "Okay, so now we find her".

Dean stands up, "Nope, I...uh, I already know where she is".

Sam raises his eyebrows and looks at Bobby who only shrugs. Sam turns his head to Dean.

"What do you mean?"

Dean went over to his bag and rummaged around, before pulling out a slightly bent file. He walks back to Sam and Bobby, giving Sam the file and grabbing himself another beer.

"What is this?" Sam asks grabbing the file.

"After Adam's funeral, I did some research-"

"You?" Sam smirked.

"I can research. I just don't see the point when I have you to do it for me".

"Sure".

"Anyway, after Adam's funeral, I looked into Emily. I found her-".

"Hold on", Sam sits straight in the chair, "You were giving me crap about wanting to find Emily, but then you went and did it-".

"Only to check on her and make sure she was living in a normal, safe town. With no strange deaths and stuff. That's all. I didn't go and knock on her door and say 'Hi, i'm your brother. Nice to meet you'".

Sam glares at him for a moment, before sighing, "So whats with the file?"

"It's everything I found about Emily. She's 15, her birthday is July 11th. It turns out that her mom died about 2 years ago, drunk driver crashed into her, and she's be in foster care ever since. Been in 3 foster home in the last 2 years and last time I checked on her, she was in Neenah, Wisconsin. I managed to pull some of her school records. She's a mini you Sammy, hasn't got a grade lower the a B-, well aside from a few months after her mom died, but that was to be expected".

Sam and Bobby share a look as Dean talks. It's clear to both of them that Dean already cared about her.

"I've got her recent school picture in the file, so we know who to look for" Dean takes a long drink from his beer. He looks over to notice Sam smirking at him, "What?"

"Nothing, it just seems like you've put a lot of effort into this file" Sam says, finally opening it up.

Dean narrows his eyes at Sam, "Bitch".

"Jerk".

"Alright, so we know where you sister is. Now how to get her" Bobby says, "I mean, it's not like you can just go up to her and tell her your her brothers and expect her to just come with you".

Dean shrugs and takes another drink, "Dunno, it might work".

"Dean" Sam exasperates.

"You got a better plan? You both said we need to get her and quickly. So we can't really wait for her to get to know us and all that crap. We should just drive up to Neenah, grab her and come back".

"You realize that's kidnapping" Sam stares at him.

"Well, technically it's teen-napping. But like I said, you got a better idea?"

Bobby shakes his head and mutters, "Idjts".

This chapter didn't really involve Emily, I know, but I just wanted to sort of set the story of how Sam and Dean found out about Emily.
In the next chapter you will meet Emily.
After that it'll be Emily and the boys :)
