Starting with Season 13 episode 6,just pretend a bit of time has passed since Castiel got back with Sam, Dean and Jack a lot earlier. 

Sam had a lot to process after the night before, you were his daughter. Not only that but you were his daughter with Sarah, the woman he still thought about. Now he was met with a dilemma should he tell you the truth? Would you even believe him? How would he get your memories back?  You told him yourself that you had no knowledge of your parents. Well now he knew why, Sarah your mother was dead and he didn't know about you. If he had, he wasn't sure what he would have done.

Just like he was unsure what to do now, he couldn't help but love you dearly. But you were in so much danger with him, and he had done things that he never wanted you to know about. Since you had read the books, you knew about everything from Jessica's death to when he jumped into the cage with Lucifer. But you had no idea he had lost his soul, he left Dean in purgatory, almost died trying to close the gates of Hell, or that he was briefly possessed by an angel. You also didn't know about Dean becoming a demon, Castiel death or his involvement with Crowley, nor did you know about Jack being Lucifer's son. But most importantly you had no idea that he got your mother killed.

Sam planned to keep it that way, he explained everything to Dean before you woke up.
"Sam you can't be serious, " Dean said in disbelief. He couldn't believe that you were his niece, by some means he guessed it made some sense. But the hunter still couldn't rap his head around it.
"Do I look like I'm joking?" Sam asked making sure to keep his voice down. He didn't want you waking up and hearing everything.

"What are you going to do?" Dean asked his brother.
"I don't know, " Sam admitted. "I don't know how to be a father Dean and without trying I dragged her into hunting, "
"Hey don't be so hard on yourself, " Dean responded before Sam could rant any further. "I know you're scared Sammy but
Y/n loves you and like I said before right now she needs you, " he continued. "One last thing, " Dean said before slapping his brother on the head. "Why didn't you use protection?" He asked. Sam told Dean to get off his back since Sarah was the first girl he loved since Jessica died.

"Everything will be okay Sam, you'll see, " Dean promised. Sam let out a heavy sigh as they both heard your footsteps. Both of them pretended nothing happened as you entered the room. You were dressed in a f/c nightgown despite the fact that you found it very kiddish.
"Is it okay to come in?" You asked rubbing your eyes sleepily.
"Of course what are you doing up early?" Sam asked you.

"I couldn't sleep anymore, I felt something and I just had to wake up, " you told him. Sam asked what you felt but you couldn't describe it, so he decided to not dwell on it. After eating Breakfast and getting dressed into a pair of jeans and green shirt with a black jacket. You left to go find Jack sitting near a table with a pencil. Castiel was standing not far away from the table. You guessed he was helping Jack with his powers. Sam and Dean followed you, which you found a bit odd but you found it comforting.

"Watch this, " Jack said once he noticed you. He made the pencil levitate for a few seconds before it dropped and he chuckled.
"Wow, " Sam said obviously impressed. You were impressed as well, never had you seen a pencil float.
"I can move the pencil. And… I found a case. Hunter's case, " Jack said.
"What kind of case.. " Dean asked but was interrupted by Jack answering and your excitement.

"Zombies, " He whispers confidentially to Cas " I know what zombies are now, " Jack continued . He pulls the came info up on the computer "You see?" He asked showing everyone what he found.  Dean asked how he found out how to us the computer.
"I helped him a bit, " you admitted hoping that was okay.
"True but by watching you,  and Sam. Three days ago, a vintage pocket watch with a personal inscription was sold at a pawn shop. " Jack explained.  "But when they went to authenticate it, they found out that it'd been buried with its owner… 20 years ago. And when they checked out the grave, it was empty. Which means… the dead are rising in Dodge City, Kansas." Jack added on.

Dean looked very happy at those words. You took a guess and thought he loved cowboys. Castiel glanced up at Dean as if he heard music, Sam noticed how excited everyone became at this news especially you.
"Right. O-or maybe it's a-a grave robbery, but…" Sam commented. Jack let out a sad oh and you looked upset.
"Yeah but we should check it out, " Dean said giving you a wink.
"Wait really?" Castiel asked in surprise.

"Yeah, we've done more on less. Besides Dodge City's kind of, uh, kind of awesome. All right, well… , " Dean responded. "Two salty hunters, one half-angel kid, a young kid and a dude who just came back from the dead, again. Team Free Will 2.0. Here we go, " Dean continued. You became very happy at those words. It seemed like you were about to go on your hunt.
"Can I go?" You asked looking pleading at Sam
"I don't know... " Sam began worried about your safety. But your begging won him over plus it was better for you to be with him than here alone.

Before you knew it, you were on the road to Dodge City with the Winchesters. Jack mostly talked with you about what else he could do, and you listened wanting to know everything. Sam watched from the passagner seat and couldn't help but smile at the sight of you. He kept these thoughts to himself though even as they arrived at the motel. You had never seen a motel before so you over the moon as you walked in, everything about the place amazed you.

"Sam this place is very nice, " you said once he stopped you from wandering off. For a thirteen year old you had the curiousity of a five year old.
"You're right it is quite nice, " Sam said placing a hand on your shoulder. "Stay close to me though, okay?" Sam told you. Without a second thought you nodded, you wanted to see how Sam did everything so you could be just like him. The check in was a bit awkward as the lady at the desk thought that you were Sam and Dean's ward.

You disliked being called that but Dean went along with it, as annoyed as you were about it. What other thing could be said about you that sounded believeable. You said nothing until everyone came across the room.
"All right, this is supposed to be the best room in the joint." Dean said as he opened the door. He switched on the light and once you saw the room, you knew he was right.
"Which room is this?" You asked as you jumped onto one of the beds.

"Oh, ho! The Wild Bill suite, " Dean answered with pride. You could tell by his voice that he was happy to be here.
"Wow, " Sam said also impressed by the western style of the room. Dean then began ranting about what he know about the room and old west. You giggled and couldn't help but shake your head.
"He really likes cowboys, " Jack said to Castiel.
"Hey, big guy. How you doin'? That's… What's going on, Calamity Jane, " Dean said to a stuffed buffalo in the room. You laughed some more and the angel couldn't help but agree with Jack.

"Yes he does, " Castiel finally said. 
"Doc Holliday! Hey-oh!" Dean exclaimed.
"This is awesome,  all right, I say quick shower, steak dinner, and then tomorrow, we hit up the cemetery, " he continued.
"Sounds like a plan, " Sam responded taking a seat next to you. A few seconds later Dean walked through a set of saloon doors, and you could hear him call out. "Oh, yes! Stirrup hangers!"

"He is very happy, " you said to Sam.
"Yes and I am glad he had been quite the opposite for awhile, " Sam responded. You felt a pang of regret but also relief at Sam's words.
"Was he depressed because you were in the cage?" You asked. However after saying that you covered your mouth realizing that wasn't something Sam would want to talk about.
"Sam has been free from the cage for years," Castiel explained to you.
"What cage?" Jack asked not knowing what that was.

You were about to tell him but at the last second decided not to. Maybe it was because you could feel the pain Sam was feeling even mentioning that.
"Nothing important, " you said to Jack. The topic was dropped and you listened to Jack and Castiel discuss where they would sleep.
"You can have the couch if you want, " Jack said to Castiel. "I don't sleep much, "
"Well I don't sleep at all, " Castiel answered. You laughed and said you would just take the couch.
"I don't know how you can function on no sleep, " you commented.

"Its complicated, " Castiel said to you.
"Y/n could you come with me please?" Sam asked and you nodded. Sam walked through the doors with you and found Dean unpacking. "I can't believe you brought your own hat, " Sam said to his brother.
"I can't believe you didn't, " Dean responded placing the hat on your head. It was big but you liked it. "Keep it kid I've got another one, " he told you.
"Thank you, " you said with a smile. Sam asked his brother if he was feeling alright since he had hardly ever seen Dean be that affectionate with a kid.

"You're in a good mood, huh?" Sam commented.
"Yeah and?" Dean asked taking out his other hat. Sam smiled at the sight because he was glad that Dean was no longer feeling hopeless.
"Its just nice to see again, " Sam admitted.
"Hey I said we needed a win and we got one, plus I did tell you everything would be okay, " Dean responded.
"Fair enough, " Sam answered. The two seemed to have forgotten you were there so you spoke up.

"Now hug, " you said playfully. They both  looked at you with confusion. "What I love it when you guys hug, "
"That's not really our style, " Dean admitted.
"Jerk, " you said with your arms crossed.
"Bitch, " Dean said out of habit. You flipped your hair and left the two alone. "She definitely inherited your sass, " Dean whispered well Sam tried not to laugh. His brother was right, you definitely were more like him than he originally thought.
