I'm extremely sorry (no I'm not) but I have a joke that I made with a friend in a role play once and I just had to do it. Excuse me. *wedges into the story*
As Dean pulled up to the house he took one glance at the black car with red interior. "Son of a- damn it. She could have called first."
"Who?" Castiel chased him to the front door.
Dean unlocked the door and threw it open, immediately getting a bucket of oatmeal dumped on his head. He blew some off of his lips and wiped it clear of his eyes. "Catherine! Show yourself." His voice was dangerously low.
A girl about Sam's age stepped out of the living room with and innocent smile. "Deany bean! What the hell happened to you?"
"Ask yourself." With crossed arms he continued forward. "Don't play innocent when you know that I know that this is your fault."
"What are you- no. Gods no, you wouldn't."
"But I would." He wrapped her in a large hug, rubbing his oatmeal covered head against her shoulder.
"Damn it Dean! This was a new jacket." She whimpered, struggling to get out of his grip.
"Maybe you shouldn't plant oatmeal traps above the front door for when I get home." Dean laughed an let her go.
"Who's this?" Castiel asked, crossing her arms.
"Ooh, someone's jelly." Catherine laughed.
"What? Why would I be a fruit spread?" Castiel's eyebrows furrowed in confusion.
"What? No it's an expression. You're thinking of jam. If someone's jelly they're jealous." Catherine laughed again. "I'm his cousin, and if anything I'd go after Sammy. He's cuter after all."
"Hey!" Dean frowned.
"You know it's true." Catherine laughed. "I'm Catherine."
"Castiel." Castiel shook Catherine's hand.
"Deans said a lot about you! I could've sworn he said you were a- oh shit."
"What? What the hell did you do?"
"Um... I may or may not... N-never mind."
"Catherine." Dean held her by her shoulders tightly, warning in his voice.
"You remember how you used to call me at midnight because you'd had a dream about Cas and you were afraid you were gay for him? Well, I may or may not be the reason why he is now a she. I found this book in the library, you know, one with spells and shit. I thought it was fake, I've read so many fakes it's not even funny."
"Get to the point."
"Well, I was inspired by your panicked called at three a.m. I decided to do some research on spells and stuff and I grabbed the spell book. While I was searching in it I found a spell that changes someone's gender. Like Cas here." She swallowed heavily. "I thought it was a load of bull crap and I found it funny. I said the incantation while thinking about Cas because you'd told me once that you wished he was a girl and I guess it worked."
"You..." Dean scowled. "Damn Cat, how do you reverse it?"
"I don't know." Catherine glanced at Castiel. "I'm so sorry."
"Cat! The next round is starting!" Sam yelled form the living room.
"Coming Sammy!" Catherine scampered back into the living room. "You're going down this time! I swear it."
Haha. I'm so evil. So guys, now you know the reason Cas is a girl. Or do you? Haha. Peace out! ~Cat.
