A/N: So, I just had this crazy idea and had to write it. That is my excuse for this. Enjoy! :) P.S. I wasn't sure about posting this story, but ImpassionedWriter said it was good, so here ya go. I dedicate this story to her :)

"So, you're here becau-" Dean stopped talking abruptly. He hoped he hadn't just seen what he thought he'd seen.

"Please tell me you didn't just pop some pills?!" Dean demanded angrily. He'd worked too hard to prevent this to be anything less than pissed.

Castiel stared at him blankly, tilting his head to the side. Dean sighed.

"Did you just take a pill of something?!" Dean clarified.

Castiel looked at the floor. He stuck out a hand toward Dean. In his hand was a bottle of pills.

Dean snatched them out of his hand. He was fully intent on giving Castiel a speech about how bad those things were, until he caught sight of the label. Tylenol, it read. Now Dean was confused.

As if Castiel was reading his thoughts, maybe he was, the fucker, Castiel said, "They help with the pain."

Alarm shot through Dean like a bullet. "Are you okay?" Dean asked.

"Yes, I'm perfectly fine, this happens every month." Castiel replied.

"Dude, what are you talking about? Did you get stabbed?!" Dean was freaking out.

"No, Dean, I did not 'get stabbed', it's merely something that happens. It happens to all seraphs."

"What happens to all seraphs?" Dean asked impatiently.

"I believe humans call it a 'menstrual cycle'. As I said, it is a normal occurrence for seraphs." Castiel said.

Dean's jaw dropped. "Dude, did you just say that you were on your period?"

"Dean, it is physically impossible for me to be on a punctuation mark. What I said was-"

"I know what you said. Period is just a different term for it. But, I thought only girls were supposed to have those. It means that you're not pregnant, and dudes can't get pregnant." Dean said.

"Dean, I am technically genderless. This body is merely a vessel. Seraphs can get pregnant, no matter what gender their vessel is." Castiel explained.

"So, it's just like when a human girl is on their period?" Dean asked.

"There are a few differences, but mostly, yes, they are the same." Castiel replied.

"Ok, but why are you here?" Dean asked.

"I merely wished to check on you and Sam. I am always concerned that Micheal or Lucifer will find a way to make you say yes. I cannot allow that to happen." Castiel said.

"We're good, for now. If we ever need help, we'll call you, don't worry." Dean replied.

"If you're sure, then I must attend to some other matters. Goodbye, Dean." Castiel said, and with a fluttering of invisible wings, he was gone.

Dean sighed in relief. Cas was awesome, but Dean was glad he was gone. Now, he could write in his journal. Yes, journal, because it definitely wasn't a diary. Ok, so, maybe it was a diary, but men can keep diaries. There was nothing wrong with writing down your feelings. It was a hell of a lot better than punching everything in your path.

July 16

Cas told me something today. He said that seraphs like him have periods and can get pregnant. He left after saying that he constantly worries about me and Sammy. He didn't call Sam 'Sammy' though. And, now all I can think of is how much I'd like to help him get rid of the whole period problem for a few months ;) I've got to take care of some boner issues now. I'll write later.

In hindsight, he really shouldn't have left his journal open to that page in plain sight. If he hadn't done that, he wouldn't've walked back into the room to see Castiel reading his journal.
