Dean couldn't help but to stare after the little kid, not only had he been able to see and hear him, he wasn't terrified of him. He found himself grinning, rather excited at the thought of finally getting back to his little brother, just to see him one last time.
Cas would be able to get him out of this hell hole whether he knew it or not. No, he wasn't going to possess the child, he was just going to give him the thing keeping him here, the amulet. Now he knew he was able to touch and grab stuff so he finally grabbed his amulet under the old fridge.
"Man, it is good to hold this." Dean says quietly to himself, feeling the cord and wiping the dust clinging away from it. If he could just get this somewhere on Cas, he'd be set and on his way at least out of this room, it was getting extremely old.
Dean grins to himself as he tosses the amulet into the next room, walking into it rather cockily, a wide grin on his face. He continued throwing his amulet into different rooms until he made it into the kid's room. He wouldn't deny that he felt sort of like a monster in a cliché movie, ready to infect his victim.
He lets a small sigh out and slowly, and quietly slipped the cord onto Cas's neck, smiling when he finally got it on. "Thanks, Cas, you have no idea how much you're going to help me." Dean says smiling, not because he thought the child was cute or innocent, but because he'd be so easy to manipulate him to get him to find Sam.
Dean noticed Cas shiver slightly and smiled, of course he would be cold, a ghost was standing right by him. He hesitantly pulled the covers up onto the child whispering, "Good night." Before taking his place beside the bed, resting.
When Cas woke he really wasn't expecting the tall man to be in his room, right by his bed. "Ister…. what are oo oing?" He asks quietly, surprised when Dean just looked at him with a slight smile. "Hey, Cas." He says as if it was common to be found in a child's room.
"Don't you have kindergarten today?" Dean reminds Cas gently, the child nodding slowly. "Eah, ut... Ota m' going ow." Cas says sliding out of bed. He glanced at the ghost, then at the weird cord around his neck, then at the amulet. He decided not to question it and just grabbed clean clothes, then looked at Dean expectantly.
The ghost sighs and turns around so Cas could get dressed. "Is your Dad cooking your breakfast?" Dean asks, breaking the silence, "No, m' going to oo it." Cas says pulling his shirt over his head. He toddled over to the kitchen, Dean following, looking mildly confused. "What do you mean you do it?" He asks.
Cas looked at him as if it was common for a child to cook for him or herself, "M' oing to oo it." He says grabbing a chair and slowly dragging it over to the counter. He reached for the cereal box, scowling slightly when Dean set it on the counter.
"You looked like you needed help." He says with a slight shrug, "No elp!" Cas responses unhappily, he could do it himself thank you very much. He really didn't want any help, he knew he could do it himself, "Well sorry, I was trying to be nice." Dean says rolling his eyes.
He didn't help Cas for the rest of the time, just watched him grab a bowl and awkwardly pour the cereal into it, he didn't even put milk in it, he just ate it. "Don't you um, want milk?" the ghost asks slowly. "No, it's too ull." Cas says with a small shrug, he really didn't mind it.
He chose to ignore the weird look Dean gave him and continued with getting ready, such as putting shoes on, cleaning his bowl, making his bed, and grabbing his backpack. "Bye Dad." He calls out, locking the door behind him, hopefully keeping the tall man in the apartment.
"So, you walk alone to school?" Cas nearly jumped when Dean just walked through the door, "Why are oo ollowing me?" He squeaks out. He wasn't sure why Dean was here, why he was following him, and why he was trying to be friendly.
"Cause, you have my amulet." That answer really didn't satisfy the child so Dean tried again, "You have my amulet so I keep you safe." He says. Sure, a flimsy lie, but Cas seemed to take it. The child walked down the stairs in silence, down the sidewalk, and to a building that Dean guessed to be the school, so it wasn't that bad of a walk, just a 2 minute one.
"A new school?" Dean asks as they walked inside. He was a little annoyed that Cas just nodded at first, then realized the kid didn't want to talk to him in public, a smart move on his part. "You're pretty smart for a kindergartener Cas." He says with a small chuckle.
The child sighs and walks into the classroom, acting as if Dean wasn't beside him. Which proved harder than he thought. Comments such as: "Look at her legs." And "Wait, is she seriously wearing that in class?" were made as he hung his backpack up, and made his way to a seat.
Cas chose to stay quiet during the few minutes the kids could talk, and scream for their parents to stay. "Cas, you know you're going to be one of the creepy kids no one wants to hang out with if you keep sitting there quietly." Dean says standing next to his desk.
Cas didn't mind at all, he'd rather be left alone. He never knew when he was going move so he chose not to make friends right away. "Seriously Cas, get out there, make a friend, laugh for once." The child glares at Dean when he attempted to move him from his seat.
"Class, settle down!" Dean stopped pushing Cas, so the child could somewhat focus on the teacher. "Now we have a new student, why don't you introduce yourself to the class?" She says smiling brightly. Dean had to groan at the cliché 'new kid in class' theme going on, as he followed Cas up to the front.
"M' Castiel, m' five." Was all Cas said before he went back to his seat, to quickly for the teacher to ask him to tell the class something else about himself. "Yeah, like a boss Cas! You show her!" Dean cheers, grinning when he actually got a small smile and a slightly stifled giggle from him.
"Great you can smile, that's something." Dean teases as the teacher moved on to her introduction. "As you all know, I'm Ms. Rotenberg, and I'll be your teacher, yay!" She says in fake enthusiasm, before moving onto the lesson.
Cas wasn't too interested in it so he didn't pay any attention to it, mainly just listening to Dean's amusing answers. "Yellow, it's yellow… wait what do you mean that's orange, that is clearly a yellow!" The Winchester growls, not noticing Cas smiling yet again.
The rest of class was fun, but not because of the lesson or the teacher, mainly because Dean was so frustrated about the smallest things. He giggles slightly as he followed the group of children outside for recess.
"What's so funny?" Dean asks a scowl set on his face as he gazed down at Cas. "Oo are funny De." The child responses with a small smile. "Was my ranging at colors funny to you?" The Winchester says in a fake angered tone, smiling when Cas nodded with a small laugh.
"Go play you strange kid." Dean says as he gently pushed Cas, slightly surprised when the child just toddled off to the empty sandbox. The Winchester just rolls his eyes and follows Cas, hoping it would be relatively easy to convince the child to help him find his brother.
He sighs to himself as he felt the amulet tug him back to Cas, hopefully, it would be easy, he honestly didn't want to be dragged through school with this kid.
