Hello everyone! I know that I wanted to post it before the next Tuesday, and it's been almost 2 months. I really apologize. I had the worst case of writer's block. I won't make any promises as to when the next chapter will be coming, but I will try really hard not to put it off for so long. Thank you for being patient with me :)

Dean's heart almost lurched out of his chest. For a moment, he was completely speechless.

"No," he exclaimed when he regained his voice.

Lucifer's eyes widened as he scoffed at what he had just heard.

"No?" Lucifer questioned. "Are you sure about that?"

Dean held his ground. "Yes," he replied, "I am definitely sure. We put you back in this hellhole for a reason, and I'm not about to undo that."

Lucifer was silent for a few moments, a look on his face that was unreadable.

"Hey, you piece of shit!" Dean cried, annoyed with the lack of response. "I am NOT going to help you, and you are going to send me back up top now!"

Lucifer smirked, and look of amusement crossing his face. "Now Dean," he said smugly, "Don't you think if I could get out, I would have by now? What makes you think I can get you out?"

A sense of deep fear set inside Dean. That was a valid point.

"If you have no idea of how to get out," Dean began tentatively, "Then how was your master plan supposed to work in the first place?" His voice was slowly increasing in volume, and he was almost shouting at this point.

"I said I don't know how to get out. But you do."

Now the terror was replaced by confusion. Why the hell did Lucifer think that? He had no clue what to do. There was nothing he could do.

Lucifer sighed with impatience and began pacing around the cell. "Wasn't Sam stuck down here at one point?"

"Well yeah, but shouldn't you know that considering your ass was down here with him?"

"Oh good," Sarcasm was oozing in Lucifer's voice, "You remember. And when his soul was stuck here? What happened then?"

"Castiel came down here and..." Dean's voice trailed off and realisation hit him.

"Exactly," The malicious grin on Lucifer's face was unbearable. "That's what I'm depending on. There's no way your brother and clingy angel friend are going to leave you down here."

"If you think Cas is going to take you along for the ride, you are seriously screwed up, "Dean muttered.

"Well obviously not. I'm not an idiot, Dean. But he will be taking you, and that's where you help me."

"I already gave you my answer. NO."

"This is how it's going to work," Lucifer continued, ignoring Dean's response. "Castiel isn't going to know he's bringing me with you."

Dean was practically fuming at this point. "Already Luci, cut the open-answers crap. Just tell me this dumbass plan already."

"Well," Lucifer said with fake offence in his voice. "Fine then, take the fun out of it then, why don't you? Let's take a trip back in time then. Remember Purgatory?"

Dean' attention immediately snapped back to the man standing across from him. "Should I even ask how you know about that? Or should I just assume it was your demon lackeys?"

"Let's go with the latter. Now," Lucifer stopped his pacing and faced Dean once again. "Remember your little friend, Benny?"

Dean took a defensive step forward. "Don't even start, Luci. Not with my friend."

Lucifer let out a small chuckle that rang around the enclosed cell. "I will take that as a 'yes'. Now do you remember how you got him out?"

Now it was Dean's eyes that widened as he slowly began piecing together what Lucifer was thinking. "No. No, there is no fucking way that's happening. Not to mention that it was a hard enough strain to bring a vampire back to life, let alone the King of Hell. It's impossible!"

"Not with that," Lucifer gestured towards Dean's arm.

The poker face was gone. Dean's face had a look of realisation and disgust over it. "You think that this... this thing," He held out his arm and pulled his sleeve up over the Mark, "is going to be able to handle your entire being inside my arm?"

Lucifer shrugged. "Not entirely sure, actually. That Mark has an immense amount of power. Might as well think optimistically and give it a try."

Dean opened his mouth to give a snarky retort, but Lucifer cut him off.

"Before you go ahead and say no, again, I should probably mention what happens if you do refuse."

Dean wanted to object, but stayed silent.

"If you don't help me, I still have my connections with my 'demon lackeys', as you so eloquently put it. I can order them to kill Castiel and your little bro Sammy in a heartbeat. Then it's just you and me, stuck here for the rest of time."

"But," Lucifer continued, "I can make you a small promise. If you help me get out of here, I won't lay a hand on your brother or your little angel. I will leave them alone."

That took Dean by surprise. "Don't you need Sam as a vessel?"

Lucifer shrugged again. "I'll figure something out. At this point I just want to get out of here."

There was a long pause. Neither Lucifer nor Dean spoke. The silence was nerving and filled with tension.

After what seemed like hours, Dean spoke. He spoke, almost at a whisper, one sole word.

"Alright."
