Cas woke to the soft sound of a guitar and someone singing Hey Jude. The Demon. He stumbled out of bed, holding his head in his hands. His arm was fully bandaged though his head hurt like hell and the sun hung low over the horizon. When he made it into the piano room he was greeted by the Demon's deep voice singing softly; "Hey Jude, don't let me down, you have found her now go and get her, remember to let her into your heart, then you can start to make it better." The voice stopped when Cas entered the room and the Demon looked up, setting the guitar aside.
"Sorry. I found your guitar, I couldn't resist." He was still in his light black clothes and red mask, but his weapons were gone and he seemed more at ease.
"I thought I said I didn't need your help. I don't make friends with criminals."
"I'm not a criminal. And you did need my help, or you'd still be in the cold, dark alley."
Cas sighed and frowned, "How long was I out?"
"About a day." The Demon replied casually, as if being unconscious for a day was no big deal.
"A day?! What about my recording session?" Cas shouted, panic creeping into his voice.
The Demon smiled, "Calm down, I rescheduled. You'll be going in tomorrow at 10 AM."
"Y-you rescheduled?" He felt his knees start to give out under him and he steadied himself on a nearby chair, "How? How long have you been here?" Cas demanded as the Demon slid from where he was sitting over to where Cas stood and wrapped an arm around him, supporting the majority of his weight.
"I've been here since I brought you. Didn't want to leave you alone in case something else happened. Oh and I called your recording studio and informed them that you were to stay in bed, Doctor's- my- orders."
"You impersonated my doctor?"
"Wouldn't say impersonated... more borrowed his identity.
"You disgust me." Cas struggled to get out of The Demon's grip to no avail.
"I'm not a criminal!" The Demon protested.
"Not a criminal?!" Cas cried, "How can you even say that? I know how many places you've robbed! How many people you've killed when they get in your way!"
"You don't understand." The Demon protested quietly, sadly, "No one does. No one gives me a chance to explain."
Cas opened his mouth to reply but the deep sadness in the Demon's eyes made him hesitate. Instead he let himself be led to his bed and carefully laid down.
"Tell me." Cas whispered, "Tell me what I don't understand."
The Demon pause, considering the offer, "I can't, not now, there's too much risk."
"So first you get my sympathy and then you tell me that you can't actually tell me anything about you? Not even your name?" Cas scoffed.
"No, I mean there's too much risk of people watching, for example the guy who attack you earlier. What did he say to you?"
"Whatever." Cas rolled his eyes, "He said I was working for you, he knew that I wrote a song about you, he knew you've been following me and he asked…" He trailed off, cursing himself for bringing that up.
"He asked you what? Castiel, this could be important!"
Cas blushed and looked away, "He asked me if we were lovers."
"Oh." Heat flooded the Demon's cheeks, matching their color to Cas', "Oh, that's not… relevant."
Cas laughed, "Why would he think we're lovers? I don't even know your name."
"Dean." The Demon replied barely audibly after a short pause and he cleared his throat to compose himself, "The name's Dean"
Cas looked back at the Demon- Dean- and furrowed his brow, "Dean? Like the name of my piece? Is that why you sounded scared when you saw the new name?"
"Yes." Dean said quietly.
"Dean." Cas said the name, trying it out, "But if you don't rob, and you're not a criminal, then why do you let yourself be called the Demon?"
"Because I'm no hero either. Maybe some good things come from my efforts, but in the eyes of everyone else and myself, I am just as much of a bad guy as the people who do rob those banks." Dean looked down, closing his eyes, "If I were to tell everyone what I was doing, no one would believe me. And if they did, I'd be called a hero and turned into something I'm not. I'm no better than the criminals."
"But you're not a criminal."
Dean gave a small smile, "You don't know that Cas, I haven't told you my story yet."
Cas tilted his head to the side, "Did you just call me Cas?"
"I… uh, yeah. Sorry." Dean apologized, slightly embarrassed.
"No, it's okay." Cas smiled and noticed for the first time the luminous green eyes hidden behind the Demon's black mask, "I like it."
"Well, Cas, I think you should get some more rest. And don't forget you have that recording session." Dean replied with a grin as he turned to walk to the window. He pushed it open and climbed onto the frame, perched like a bird, "Until next time, Cas." He pushed away from the window and disappeared from view.
Cas bolted to the window with a gasp just in time to see the outline of a dark figure against the pale sky. "Goodbye…Dean."
A chill washed over Cas, waking him from his sleep and shaking him from his dreams of jumping over rooftops and black masks. He rolled out of bed and walked over to the window to close it. He hesitated, hands hovering over the frame and turned away instead to sit at the piano. Once again he played the strange melody if Dean's Theme as let the notes ring out into the night and up over the city. He played for a long time, improvising new parts, trying different things. Eventually, he got back up and returned to the window, this time pushing it back into place.
"So you're just gonna shut me out now, Cas?" A deep voice came from outside, "And I thought we were friends."
