A/N: Hope you're liking the story so far. Here's the explanation. Please give me reviews, they're like Supernatural, they give me confidence and happiness.
"I am 4 billion and 5 years old, and have been alive to see the birth of this universe."
"What?!" Both Winchesters exclaimed at the same time. "So there are other universes?" Sam asked.
"Yes. Lots more. In them are vast amounts of species and races, and I have had the pleasure of exploring them. Well, most of them." Sam decided he needed to sit down on the bed, and Dean decided that he needed a beer to help him properly process all that was being said. "Okay." Sam continued. "So, who are you?" Clara gave a small smile. "I am Clarithrina Olivia Ozweld, quientenne, 4 billion and 5 years old. I am the wife of the Angel Castiel and I am older than most creations."
"How did you become Cas' wife?" Dean asked, leaning forward from the counter. Clara smiled at him, looking happy at his involvment. "I was on the run, as per usual." She chuckled. "Castiel saved me from some very nasty customers, and we became very good friends. But Castiel wanted something stable, something material to prove our friendship. Now, there isn't really anyway to prove friendship on paper, so we got married. But marrying your best friend is good if you want a healthy relationship." She winked at Dean, leaning back into Cas. "What else would you like to know?"
"Why are you here now?" Dean questioned. Clara smiled again. She seemed to do that a lot.
"To help you."
"Us?" Sam asked. Clara nodded, and got up to walk over to the fridge. He skirt swished as she walked.
"Can I have a beer? I'm really quite thirsty." She looked imploringly at Dean. He nodded, not seeing any harm in it. "Yes." She replied to Sam's question. "To help you. All of you. See, I've been looking and you really have got yourselves in a bit of a pickle haven't you? What with him-" she gestured to Cas with her beer bottle. " 'Betraying' Heaven, and Metatron, and all that shit going on, and this whole Darkness thing, you really need some help. So I'm here to offer it. Along with my family."
"The people in the diner?" Dean clarified. Clara nodded at him.
"We are here to help you fix the problems you have, not to cause more. We are on your side." She gave them a wide smile and put the bottle down on the side. "I'm off to check in. And bring my family up. Have fun while I'm gone." She walked to the door, then twisted her head back to look at Cas. "Behave." Cas gave her a sarcastic smile. "Don't I always?" Clara laughed at that and was gone.
"And lets welcome new Cas to town." Dean sighed and raised his beer.
