"So, what do you want to know this time, Curious George?" He sighed, holding a cup of coffee since it was too early for him to even function properly. But then again, you found out something new and that meant explaining it to you.
You were a very curious angel — even more than Castiel. You had a thousand questions a second and sometimes, Dean found it difficult to keep up with you and your curiosity. But he tried his best to explain all these new and different things to you. He found it endearing how excited you could get over the things that for him were nothing special. You were his little ray of sunshine and felt the immense need to protect you, even though you were a literal celestial being, ten times stronger than he was.
"What's Halloween?" You asked, walking in circles around the bunker's kitchen.
Dean sighed and pointed at you with his finger and then at the chair in front of him. "Sit down, you're giving me headache with that walking," he muttered, taking a sip of his coffee. You nodded and quickly sat down, tilting your head to the side as you looked at him. "That's better," he hummed.
"So, what's Halloween?" You repeated, leaning forward.
"To put it simply for you, birdie, it's a day in the year when people dress up, watch scary movies, do spooky things and kids go trick or treating. Why do you want to know? You want to dress up?" He asked with a smile, scratching his cheek with faint stubble. "Or maybe carve a pumpkin?"
"What's that?" You asked with wide eyes and Dean chuckled.
"Nothing drastic. Just giving pumpkins scary faces. Or funny ones. Depends," he shrugged his arms. "You know what, I think we should do something. Let me show you what's the deal about, birdie" he said and smiled, seeing that you immediately got excited at his words.
