"Look, Dean. I've told you already!" Holy water and salt are tossed in the captive's face. There is no reaction at all.

"How the Hell do you even know my name?" Dean exclaims. The room is dark and musty. The walls are covered in planks of polished cedar, no paint or wallpaper in sight. A young girl in her late teens is slouched in a single-seat leather couch, blood dripping from the right side of her head and left cheek.

"Cas." She muttered the single word. The name causes Dean's expression to change from rage to confusion. "Castiel. I know you know him."

"Why do you know who I am? Why do you know Cas? Or how?" With every question Dean's voice became louder and louder, such a high volume that the window panes rattle in their frames. There is something too strange about this girl showing up in the middle of the case, too strange to be just a coincidence, Deans thinks.

Frustrated, Dean paces back and forth, grabbing a beer bottle and taking a quick swig.

"Dean, a word with you?" Sam asks patiently. The worried and just as confused little brother confronts Dean about the whole confusing situation."Look, I know this sounds really crazy, but maybe she can help us. We have had no new leads and she says she knows Cas."

"I'm really sick of all this Cas nonsense. Mr. Disappear has left me in the dust too many times. I've almost died every time! Cas so far is no friend of mine," Dean elaborates.

From the other room, there's a sudden flash of light and gust of wind. Almost immediately Dean and Sam rush in, only to find the angel in question standing in front of their mystery guest.

"Cas! I found them!" the girl exclaims.

"So, now that you're here, care to explain what the hell is going on?" Dean asks with urgency.

"Elise is here to help you. She is also, in a way, my student. I guided her and she is a very special person who you may find useful in your cases… and for the grand scheme of things," Cas explains in monotone.

"Wait, Elise? Student? Grand scheme of things?" Sam stares confused.

"My name is Elise Renard. My name tells my story," she pauses. Sam and Dean stare blankly at her, feeling out of the loop. "Cas has already explained a while ago the whole St. Michael and Lucifer prophecy to you. In a way, you two represent Heaven and Hell in coexistence. Dean was going to be the vessel of St. Michael and Sam, the vessel or replacement of Lucifer."

"Hold on," Sam interjects, "replacement?"

"Well," Elise begins, "things in Hell are a little more violent, as pop culture has led everyone to believe. And you having demon blood in you but being human, makes you have stronger abilities than any demon can even imagine of manifesting. Some want to say that being human is a weakness, but it has been a strength now hasn't it?"

Sam shows a puzzled yet understanding look. Reading the realization, Dean interrupts, "So what does all of this have to do with you."

"First name: God's oath. Last name: fox, in nature perceived as a trickster with a touch of loyalty. That's what my name means. I represent you both in one unit."

"But I thought we stopped the Apocalypse?" Dean asks suspiciously and hastily to Cas.

"That was the old world order. Ever since you two stopped it all and prevented eternal chaos, I took it upon myself to preserve that balance. Elise has power and is under my guidance. She has been disconnected for so long from her family, that she came to realize and obtain her true ability." Dean and Sam look at Cas in searching manner.

"You care about her," Dean chuckled. "The angel found human emotion."

"If you think about it, he's always had emotions. How else would he have realized he needed to help you stop the Apocalypse and Zachariah? Without an angel's powers to support your escape, this place would be a whole lot different," Elise elaborates.

"Thank you Elise. Anyway," Cas continues relieving his smile, "there's danger ahead for you two. There's battles I will partake in along your sides but there's something I have to take care of first. I'm leaving Elise here with you. You will figure out why soon enough."

"Why can't you just tell us?!" Dean exclaims just as Cas disappears.
