Kind Of A Sister
As if it wasn’t weird enough that Sam and Dean suddenly had a teenaged half-brother, he had a little half-sister, so in some weird way, that meant Sam and Dean had a little half-sister.
“My head’s spinning,” Dean said. “I can’t wrap my mind around this. Dad had another kid… and he treated him the way any father should treat a son… and then the woman who he had a kid with had another kid with another guy?”
“I guess so,” Sam said. He watched as Adam crouched down next to you, talking to you about the two newcomers.
“So… she’s technically related to us…?”
“Kind of… not really by blood… I think.”
Adam took you by the hand and led you over to the elder Winchesters. “Y/N, this is Sam and Dean. They’re… friends of mine.”
You peered up at the men with large eyes. After a few moments, you gave them a small wave before stepping partially behind Adam.
“So,” Adam said. “Can we talk about John? I want to know more about him. And you two.”
Being Winchesters, it was no surprise that Sam and Dean’s life got way more complicated and began to almost spiral out of control. The family drama with Adam (and you? They still weren’t sure of the family tree logistics) was put on the backburner while the brothers dealt with ghouls.
Unfortunately, the backburner turned into the front burner when the Winchesters discovered that their new brother and his mother were the ghouls they were hunting.
They were able to kill them but that was only the beginning of their problems.
“Oh, shit,” Sam said, his eyes falling to the corner of the room.
Dean looked over, spotting you curled into a ball. “Dammit… did she see us…?”
“I think so,” Sam said. He took a few steps over to you, causing you to shrink into yourself with a slight whimper. “Hey, Y/N, it’s okay. It’s okay.”
You shook your head, your tears glistening on your cheeks.
“Sweetheart?” Dean said, stepping beside his brother. The two of them crouched down, getting closer to your eye level. “Remember us? Dean and Sam? Friends of your brother?”
“A-Adam,” you said with a slight hiccup, tears falling harder. “Y-you…”
Dean smacked Sam in the arm as he stood. The two crossed back over to the other side of the room. “This is not good,” Dean said, his voice low. “We’ve got to get her out of here.”
“I don’t think she’ll let us get near her,” Sam said. “She thinks we killed her brother.”
“Well, I mean, we kind of did.” Dean glanced back over at you. “What are we going to do?”
Sam shook his head, chewing on the inside of his lip.
“Wait,” Dean said. “What about Cas?”
“What about him?”
“Maybe he can like, wipe her memory or something.”
Sam shrugged. “Maybe. But it’s not like we have a lot of other options.”
Cas showed up at Dean’s call and the brothers explained the situation.
“Can you help us? Help her?” Dean asked.
“I can try.”
The brothers watched as Cas carefully approached you, crouching down near you.
“Y/N,” he said, his voice soft. “My name is Castiel.”
You said nothing, but your tears subsided slightly.
“I’m an angel of the Lord. I hear you’ve gone through something horrible.”
You nodded once.
“Can you tell me what happened?”
“M-my brother… Adam…”
“What happened to Adam?”
“His f-friends… th-they hurt him.”
Cas nodded. “I see. I’m very sorry that that happened.”
“I want him b-back.”
“I’m sure you do.” Cas was quiet for a moment. “Y/N, I would like to help you. Will you let me?”
You were still for a few moments before nodding once. Cas slowly reached forward, pressing two fingers to your forehead.
“Christ, I hope this works,” Dean said, watching from the hallway.
“No child should have to see what she did,” Sam agreed.
The brothers watched as Cas stood, picking you up and placing you on his hip. He walked over to Sam and Dean.
“See, Y/N,” Cas said gently. “I told you your brothers were looking for you.”
You peered at the Winchesters, your head resting on the angel’s shoulder. But at least you’d stopped crying.
“Y/N, will you go with Sam? I need to talk to Dean for a moment.”
You nodded and reached out for Sam. He took you from Cas, feeling you wrap around him, holding on tight. Dean handed him the keys to the Impala and Sam took you outside.
“So?” Dean asked when his brother’s footsteps had disappeared. “She good?”
“I have erased the memory of what truly happened here. But… she was still in distress. I couldn’t let her walk out of here with any memory of her brother.”
“So… what’d you do?”
“I took everything about Adam away from her. Because she’s at such a young age, it was easy to manipulate her mind to accept you and Sam as her true brothers.”
Dean’s first instinct was to be pissed, but he knew that he and Sam were literally the last things you had. Your brother was dead, your mother was dead, who knew where your father was. They were the closest thing to family for you.
“Thanks,” Dean said, clapping a hand on Cas’ shoulder. “You got us out of a tricky situation.”
“Take care of her. She needs it.”
Dean nodded and headed outside. He saw Sam sitting in the backseat next to you. When he noticed Dean approaching, he got out and carefully shut the door. Dean saw your eyes looking at him from behind Sam.
“Cas took away every memory of Adam.”
Sam nodded. “And… when he said that we were…”
“We’re all she’s got, Sam.”
The brothers looked at you, trying to give you reassuring smiles. You gave them a small smile; the tears from earlier seemed like a distant memory.
“Well,” Sam said, turning back to Dean. “It’s not the first time we’ve taken someone in, let them join our family.”
Dean nodded. “Having a sister can’t be all that bad, right?”
