A/N: This chapter is a little bit longer than the first one, and I hope I'd manage to keep the next that long as well. Sorry for any typos and mistakes. Feel free to correct me if you notice any.

Summary: Angels were watching him, that's what Mom always said before she put him to bed. He remembered that. Why, then, Dean believed angels did not exist for so long? He wasn't always like that.

I own nothing.

Chapter 2:

Mom was in the hospital again. This time, though, it was because she had to go and bring Sammy home. Daddy went with her, and one of the nice neighbors stayed with him at the house to wait. Dean was so excited.

He sat on the edge of the couch in the living-room, kicking his legs back and forth impatiently, chewing his lower lip. The nice neighbor – Missouri – said his parents won't be back home for at least five or six more hours, and Dean already had enough waiting. The sun was disappearing in the horizon, too late to go to the park, he thought sadly.

He missed Castiel.

He hadn't seen the older boy for more than a week now. That one meeting they had in the park was one Dean could not get out of his head. He told his mother all he knew about this mysterious Castiel, and when Daddy put him to bed that night, he made him promise to take him back to the park the next day, to meet him again.

But the next day, Castiel was nowhere to be seen.

He went with John to the park every day for the past week, hoping to see his friend again. And every day, he came back home with lowered face and big, sad green eyes. It broke Mary's heart.

Now, concerned with thoughts of his parents, his new brother and his missing friend, he couldn't just sit quietly. Dean's shoulders tensed for a second in hesitation, and then he nodded to himself and leaped off the couch, heading straight to the house's front door. Missouri looked up from the dinner she was cooking for him and eyed him suspiciously.

"Where are you going, young man?" she asked sharply. Dean jumped, then turned and gave her his brightest smile.

"Out." He said innocently. "To the yard, that's all, I promise." Missouri looked like she was considering the idea, narrowing her eyes for a second.

"Fine." She said at last, and Dean's chest was filled with relief. "But you are not going past the yard's gate, understood?"

"Yes, Ma'am!"

"Good. Come back inside in time for dinner."

And he was gone before she could change her mind.

It was chilly outside, but Dean didn't dare going back inside to take his jacket, in case Missouri would decide he should stay indoor. He walked towards the beaten swing his father made him last year from a piece of wood and an old rope tied to a tree, and sat in it, swinging his legs and kicking the short grass.

So quiet.

He heard a soft flutter of wings somewhere around him, and looked up at the tree curiously, trying to catch the bird with his eyes. He couldn't see a thing.

"Hello, Dean."

Dean jumped in his place on the swing, but his heart jumped even higher as he recognized the quiet, monotonous voice. He looked aside and smiled brightly as Castiel made his way towards him. If Dean wasn't so excited to see him, he would have wondered how could Castiel come from inside the thick bushes.

"Cass!" He called happily, leaping off the swing and hurrying toward his older friend. He hugged him tightly for a brief moment before letting go and staring up at the slightly taller boy. "Where have you been?" He asked, his lower lip curling for a second in a gentle scowl before switching back to a smile. Castiel looked at him blankly.

"I was... busy." He avoided the question, then lowered his head briefly. "I apologize."

Dean giggled. "You're talking real funny." He commented. "But I forgive you." Castiel shrugged, flashing him a small and shy smile. Dean smiled back and walked towards the swing, sitting on the grass next to the tall tree and crossing his legs. "Come here," He called, seeing Castiel kept standing motionless where he left him. The older boy nodded and approached Dean, gracefully sinking into a sitting position in front of him.

"Do you wanna play?" Dean asked after a few seconds of silence, realizing his friend was content with simply sitting there quietly and staring at Dean for hours. It made him slightly uncomfortable, but it was funny, too. Dean's voice tore the other boy out of his thoughts, and he blinked at Dean in confusion, as if he was in another world. He nodded, and Dean reached for a small ball that was behind the tree, not far from his swing.

"How?" Castiel asked curiously. Dean stared at him in surprise.

"You never played with someone?" He gaped at him. Castiel shook his head slowly.

"No."

"I'll teach you, then."

And they played. Dean started with rolling the ball towards Castiel, nodding in approval when the other boy rolled it hesitantly back, getting the idea. They started throwing it at each other, but Dean quickly got tired of the game alone. "Where are you from?" He suddenly asked. Castiel tensed, almost missing the ball Dean threw at him.

"Lawrence..." He said, and it sounded more like a question. Dean frowned.

"I don't understand."

"It's... complicated." Castiel avoided the answer awkwardly. Dean shrugged.

"Okay." He nodded, then smiled. "I'm having a little brother, you know?" He informed the older boy enthusiastically. Castiel watched him quietly for a few seconds, and a shy smile stretched his chapped lips.

"That's joyful." He said. Dean laughed. Castiel was weird, and he talked funny, but Dean liked him.

"It is." He smiled brightly. "Mom said his name is going to be Sam. She didn't say why, though."

"It's a nice name." Castiel replied, throwing the ball at Dean. The younger boy caught it, tapping on it twice with his palms.

"You have a nice name, too." He said, throwing it back at Castiel. "What does it mean?"

"It's an angel's name." Castiel said quietly, throwing the ball back and waiting for Dean to do the same. When he didn't, Castiel frowned a little, tilting his head at Dean's expression.

"Are you an angel...?" The little boy whispered in awe. Castiel swallowed hard, and nodded slowly, worridly. "Wow...!" Dean's green eyes lit in excitement. Castiel seemed surprised by his reaction.

"Aren't you scared?" He asked quietly. From his experience with the human kind, people didn't tend to accept that so easily. Dean shook his head passionately, leaving the ball and quickly crawling to sit closer to his friend, watching him in awe.

"Can you do magic?" He asked, huge green eyes shining. Castiel looked around him worriedly, but when he saw no one was around, he nodded again. He plucked a long blade of grass from the ground and held it between his fingers. Dean watched with his mouth slightly open, as a small blue flower started blooming in front of his eyes, spreading it's petals. He couldn't find words to tell Castiel how amazing he found this.

"That's so cool, Cass...!" He called at last, eyes shooting fire. "You're awesome!" Castiel smiled sheepishly, delicate blush tinting his ears at the compliments. He was happy to make Dean happy.

They didn't even get the chance to discuss it properly, before Missouri's firm and commanding voice called out for Dean to get his ass in the house in five seconds. Dean glanced at the front door and bit his lip, looking back at Castiel. He didn't want his friend to go so soon – not after so long without seeing him at all. A thought suddenly occurred to him, and he smiled brightly.

"Say," He asked Castiel. "Do you want to come in? My parents aren't at home, and Missouri is really nice if you keep your mouth shut." He giggled. "We could eat dinner and watch a movie or something." He offered, waiting anxiously for Castiel's answer. The older boy looked hesitant, but eventually he nodded, seeing Dean's expecting expression.

"Alright."

"Great!" Dean called happily, dragging his friend to the house by the hand.

"but, Dean- Dean, wait...!" He tried to say, attempting to get the other's attention. They stopped on the front porch, and Dean turned to look at Castiel, the smile still on his lips.

"What?"

"You must keep this in secret, okay?" Castiel stared at him seriously. Dean's smile flickered for a brief moment, but he nodded.

"Sure."

Inside, Missouri was already standing impatiently by the table, watching suspiciously as Dean dragged an older-looking boy inside the house. Something about this blue-eyed kid seemed strange to her, but she couldn't put her finger on it. What she knew for sure, he wasn't human. He was different from anything she'd ever seen... but she said nothing. The vibe she sensed was gentle and sincere. It was okay.

"Would you introduce me your little friend?" Missouri raised an eyebrow at Dean. The Winchester boy smiled brightly at her. She already knew, this boy will become one handsome man one day.

"This is Cass," Dean said, pushing his nervous friend forward.

"It's Castiel." He corrected him, offering his hand to shake Missouri's. She smirked.

"You're quite the gentleman." She commented appreciatively, glancing at Dean. "You should learn from him." Dean just shrugged.

They had a great evening. They watched a movie Missouri brought them, and she even was nice enough to bring them some chocolate from Mary's hidden box, where she kept all the candies for Dean. Mary Winchester knew her son too well to let him eat chocolate freely. It was Castiel's first time ever tasting chocolate, and the overwhelmed gasp he let out as the small piece melted on his tongue was priceless. Dean laughed until his stomach hurt. Castiel blushed.

The evening passed without them noticing, and Dean soon fell asleep on the couch a few hours later, with his head gently resting on Castiel's shoulder. The older boy did not move a muscle, and only smiled fondly down at him. Missouri watched the boys carefully for a while from her place next to the table.

"Do you want me to take you home, honey?" She asked Castiel quietly. He looked up at her in silence for a moment, and shook his head slowly.

"No, thank you." He said. "I know the way."

"Are you sure?" She insisted. "It's pretty late." Castiel sighed.

"It's alright. There is no need to pretend now." He said quietly, glancing down at Dean, who slept soundly on his shoulder. He moved him carefully to lean against the sofa's pillows, looking back at the woman. "I know you know."

Missouri tensed.

"And?" She asked. Castiel tilted his head in question. She frowned. "And, do I have a reason to worry?"

"No." The little boy answered quietly, his tone much more ancient than his looks.

"That's good." She smiled weakly, and he disappeared.

The next morning, Dean woke up in his bed to the sound of a thin cry of a newborn baby. His parents were home, and that meant that Sammy was, too. He jumped out of bed and ran to the nursery, an excited glint in his sleepy eyes. His mother was already there, picking a tiny baby up of the crib. When she noticed Dean, though, she turned and smiled at him tiredly.

"Good morning, sweetie." Mary whispered gently. "Come here, meet your new baby brother."

A/N: So. I'd really like to hear what you think, okay? So, review?
