Sam and Dean both leaned in attentively while Castiel looked perplexed.

"Well? Let's have it." Dean urged.

Rowena picked up the book and handed it to him. The book Crowley had found was in fact a spell book, stolen from a coven of witches in the mid eighteenth century. The bindings were old and the pages faded and yellowed, but it was still legible. Some of the ink on the pages was a bit smudged, as if someone had written things down in a hurry and had been unable to wait for the ink to dry. This page, however, remained pristine, as if it knew it was someday going to be a help to someone.

Dean glanced at it. His face went from curious to skeptical in about three seconds.

"An immobility spell? How is that going to help?"

Rowena sighed and rolled her eyes. Once again, the Winchester boys were oblivious.

"Did you even bother to read through any of it?" She asked. Dean scowled at her and kept reading. At the end, he quirked an eyebrow.

"It's a potion?" He asked, completely thrown off.

"Aye, that it is."

Dean was stumped. "How is this going to help keep him in the cage?"

Rowena shook her head. "Don't you see? If we coat the bars of the cage with the potion it could stop him from escaping. That spell is impervious to the powers of Demons and Angels. Neither of them could bring him back, and anybody who got in the cage to try and free him-"

"Would be unable to move." Finished Sam. Dean and Cas finally caught up to where they were already.

Rowena nodded, smiling proudly at her clever boy.

"That's brilliant." Sam remarked in surprise. Rowena smiled smugly at him.

"What else is new?" She asked, laughing. Then, she kissed her son's temple, making him giggle slightly. It made her smile grow even wider. When he started to try and wiggle against her grasp again, she put him down, enjoying the sound of his consistent babbling as a background noise to her conversation. She tuned back in to hear Sam and Dean arguing.

"There's one problem with your plan- how the hell are we supposed to get out once everything is coated?"

That stopped Sam in his tracks. He tried to find a good reply, but none came. His brother had him cornered there. What could help with that?

Rowena decided to chime in. "I know a levitation spell that might come in handy."

Sam shot dean a knowing look, as if to say "I told you so".

Dean just looked at him, smiling a little. "Bitch."

"Jerk." The two of them shared a grin.

"How long does this potion take to make?" Asked Castiel.

"Not long. An hour and a half tops."

"And the levitation spell?"

"Piece of cake. Nothing I can't do in a pinch."

"Guys, I think we're missing one vital question here." Said Sam. The three of them looked at him curiously.

"How are we getting Lucifer back in there?"

Cas and Dean considered this for a moment, but Rowena wasted no time in charging ahead of them.

"I'll be glad to do the honors on that one."

Six pairs of eyes turned to look at her. There was no doubt that she meant what she said, but they were skeptical as to wether or not her motives were pure and her loyalty was entirely on their side. She sighed.

"Lucifer snapped my neck, partnered with my abusive bampot ex, and terrorized my son and drove us away from our homes. He has been toying with my family for far too long. It's high time he paid the price for what he's done. I won't stop until I have his head on a platter. I won't let him get away with it. Not this time. When I'm through with him, he'll wish he'd never been created."

Silence met the statement, and Castiel shifted uncomfortably in his seat. Dean took a too-long drink of beer, and Sam appeared to be the only one listening to her. He nodded.

Dean, now slightly intoxicated, asked the question they were all thinking.

"How do we know You'll stay on our side and not switch at the last minute like you have for pretty much every major fight we've been in?"

Rowena had opened her mouth and was about to protest his accusation when she heard it. The lack of sound. More specifically, the lack of sound from her son. It wasn't uncommon for Fergus to get tired and fall asleep after playing a while, but considering that he had just woken up from his not-quite-a-nap-but-still-not-a-sleep, she knew that wasn't likely. The silence settled over the room, and it didn't take more than a half second for Rowena to become incredibly suspicious. She got up from her seat so quickly that it rattled her teacup against the china.

"Fergus?" She called. There was no answer. It took less than the space of a heartbeat for her anxiety to skyrocket. "Fergus, where are you?" She tried again. She walked around the corner, and was met with a sight that melted her heart.

There sat her little boy, with a look of concentration on his face. He had somehow managed to find a small bowl, and had found some type of seemingly sticky substance and filled the bowl with it. He was currently staring at his hands, which were coated with it, like they were the most fascinating things he'd ever scene. Rowena laughed delightedly and scooped up her inquisitive child, just in time to stop him from putting his fingers in his mouth.

"Now Fergus, don't do that! Your fingers are dirty!" She scolded gently as she took him to the sink to clean his hands. When he looked at her, obviously angry about his fingers being taken away, she quickly replaced it with a pacifier and took him back to the table in her lap. She looked each of them in the face and paused a long moment before speaking again.

"This is why I'm fighting." She said solemnly.

Slowly, approvingly, they all nodded. She was serious this time. They formed a pact together.

This time, they were taking Lucifer out for good
