Sam didn't want to lose his brother once again, especially not after he finally admitted that he was proud of them. This was something the younger Winchester always wanted to hear from his older brother, which he looked up to since the very beginning of his life. So while his hands were shaking, he prepared everything to summon Crowley to him, his entire hope laying on the demon – who called himself the King of Hell – wishing, that he could bring his brother from the dead. After all, they had been through so much that this was not acceptable anymore to let go, like he did last time. Even know he regretted that he moved on, while Dean had been in Purgatory by himself. This time he would save him, no matter what it would cost.
Meanwhile Crowley already appeared in front of the room, where Dean was laying there, silently like a dead corpse. Slowly he walked inside and sat down, knowing that it would be hard for him to say the words, which he was about to speak out loud. After all he was quite fond of Dean by now, because he could tease him way too easy and while the Winchester was stuck with the mark of Cain, Crowley and Dean got a bit closer – almost like friends, even if the hunter would never admit such a fact. So while he watched him, he started to speak what was on his mind:
"Your brother, bless his soul, is summoning me as I speak. Make a deal, bring you back. It's exactly what I was talking about, isn't it? It's all become so expected. You have to believe me, when I suggested you take on the mark of Cain I didn't know this was going to happen. Not really. I mean, I might not have told you the entire truth, but I never lied. I never lied Dean! That's important. It's fundamental. But there is one story about Cain that I might have forgotten to tell you. Apparently he too was willing to accept death rather than becoming the killer the mark wanted him to be. So he took his own life with the blade. He died. Except, as rumors has it, the mark never quite let go. You can understand why I never spoke of this. Why set hearts a flutter at mere speculation? It wasn't until you summoned me, no, it wasn't truly until you left that cheeseburger uneaten, that I began to let myself believe maybe miracles do come true. Listen to me Dean Winchester, what you're feeling right now it's not death. It's life - a new kind of life. Open your eyes Dean see what I see, feel what I feel. Let's take a howl at that moon."
While he was still speaking, Crowley placed the blade into Dean's hands. He knew too well, that Dean thought of himself being dead, but even though no single muscle was moving underneath the hunter's skin, the demon felt the presence of a new star rising upon Hell. And when he told him to open up his eyes and experience the things he himself experienced before, Dean Winchester opened his new gained black eyes of a demon. A pressure of Crowley's shoulder was lifted away, as he saw him being alive and one of his own kind. It was a wish, the King had since quite a longer time already. Dean was a sassy guy, who was not suited into this life of a hero – not at all. He was supposed to be in Hell, since he sold his soul to save his younger brother. And it was just a matter of time, until this change would happen. And now it finally happened for real. A half smile crossed Crowley's right side, as he kept looking down onto his new fellow. Before he could feel the tickling on his skin from disappearing, he told Dean a place to meet each other, as he disappeared to reappear directly in front of Sam.
The younger Winchester was being all torn apart from the emotions he went through, while Crowley seemed to be too coldhearted, even now. After some brief seconds of silence, Sam opened his mouth to ask him for help. He would do anything to get his brother back. But before he was even able to speak on word, the demon raised his right index-finger and shut him up in surprise. Then he just explained: "He's alive and already gone – go and check it yourself, if you don't believe me."
Sam frowned in irritation, since those words made not much sense. He himself saw Dean dying before and beside that, a demon would never help a hunter just out of friendship without any profit on his own. But he couldn't wait any second to discuss this. The tall human ran over into his brother's room just to find it empty. There was a small note on the bed, which said: "Sammy let me go". His mind was spinning and he was not able to believe this truth, even though he could tell that those words were written by his brother Dean. What just happened while he was summoning the King? Wanting to know the truth, he ran back to the place where he left Crowley before, but of course he was gone already. So now he was in the bunker all by himself, while his brother apparently was alive and leaving him behind. Nothing made sense anymore for the moment, as Sam Winchester just rested his body against the closest wall and slowly moving down onto the ground, not able to understand the whole situation.
Meanwhile Crowley snapped himself to the meeting point, waiting for Dean to arrive. As he drove by with the Impala, the King smirked amused of how rough he stepped onto the brakes. "I thought this is your beloved baby?" he asked almost teasingly, as he watched Dean getting out of the car. The new demon shrugged totally bored by this question, as he answered: "I don't really care anymore." And to prove his words, he threw the keys to his new boss and walked over to the passenger's seat, while saying: "You can enjoy yourself while having a ride."
Seeing Dean like this surely impressed Crowley, so he smirked once more, as he got into the car to drive to them away – as far as possible, so they would have some peace from Sam, who probably suffered enough to run after them. But Crowley just wanted to enjoy some time with Dean, knowing that the younger Winchester would do everything possible to bring his brother back to his normal life - with a soul and being a hunter, no matter how painful this would become.
