I've recently been reading this amazing fic called How to Keep a Happy Marital Home (While Sleeping With Your Husband's Brother) by @xev3n and @cheesecakekiss.
The title is pretty self explanatory. Dean is unhappily married to Jimmy, but keeping it together, when ex-con Cas shows up and starts being a menace. I have a weakness for Evil Cas, especially if tattooed (let's not analyze this further, please).
There's a scene where Cas creeps on Dean and Jimmy in bed that stood out to me as Something I Have To Draw. So I did, and here is the result! I had so much fun with the tattoos – they're not described in detail in the text (yet, perhaps, it's on chapter 4 of 9), so I took some liberties in interpreting how they'd look. Doesn't Cas look very trustworthy and not the slightest bit manipulative? It even says so on the chest!
Anyway, go read the fic, bask in dark!Cas goodness, it'll be worth it.
Spn where it's really shown how Castiel is not human
Cas choosing not to come to the Winchesters prayers when he was mad at them
Killing animals he found that were sick and/or dying, thinking that it was "best" for them
Not understanding empathy or social cues at all, but not in the 'funny quirky way'. in the way of him being horribly insensitive and rude
Cas never stopping thinking of Sam as an abomination due to the demon blood he can always smell running through Sam's veins
Cas once calling Sam a "half-blood demon" when introducing Sam and Dean to another angel
Killing demons ruthlessly, not even trying to spare vessels because all he can see is the smoke and evil of the demon and he forgets that there may be a human inside crying for help
He doesn't breathe or blink, and will sit perfectly still staring into nothing (which is very creepy)
Bringing up both Sam and Dean's horrible trauma without thinking or even really caring about how much it might affect them (ex: the Cage and Lucifer, Hell and Alistair)
Talking with pride about the thousands of beings he has slaughtered in past wars he had been in hundreds/ thousands of years ago

Cas had been human for a few weeks, and it was still unnerving not to run into him somewhere in the bunker early in the morning. The ex-angel had his own room that seemed to spend more time untouched, but Sam and Jack never mention it. And Sam definitely didn’t mention the questionable sounds from his brother’s room.
Sam’s eyes were still gritty with sleep as he stumbled into the kitchen, nearly jumping out of his skin at Jack’s cheery greeting. “Mornin’ Jack.” Sam blinked a few times, his vision clearing the longer he focused on the Nephilim leaning on the table.
“Cereal?” Jack gently shook the box of sugary cereal at Sam, smiling around his mouthful.
“No, thanks,” Sam hummed, smiling sleepily. He staggered over to the coffee pot, fumbling around until he successfully got the coffee brewing. “Why are you up?” Sam dropped into the chair opposite Jack, opening his eyes wider than needed in hopes of chasing off the last lingering wisps of sleep.
“I couldn’t sleep anymore,” Jack sighed, resting his cheek on his fist.
“How long have you been up?”
“A few hours,” Jack confessed, pushing a stray piece of cereal around his bowl. “I figured you’d be up around now, so I came looking for breakfast.”
“Is that what you usually do?” Sam asked as he slid off his chair towards the beeping coffee pot.
“No,” Jack mumbled. “But there’s no one else up now.” Sam’s heart ached when he realized the issue.
“Cas isn’t up anymore,” Sam breathed.
“I’m so happy he’s adjusting so well,” Jack rushed out, snapping his eyes up to meet Sam’s.
“Jack,” Sam started, dropping onto his chair again and reaching for Jack’s hand. “It’s okay to miss Cas being an angel, and it doesn’t make you a bad person for being upset about it.”
“I know,” Jack sighed, dropping his eyes to his bowl of milk. Sam’s ears perked at the sound of footsteps moving down the hall, and he pulled his phone out, checking the time.
“Who the hell’s moving around at 6 am?” Sam mumbled to himself. Jack squinted at him, following his line of sight to the kitchen door. Dean and Cas appear in the doorway, but Sam instantly knew something was wrong. His brother and the ex-angel were both sporting a hollow, haunted look in their eyes, and they both look more exhausted than they did the night before. Dean’s lips were slightly parted, his green eyes looked dull and sunken in; Cas stepped around him, looking paler than Sam had ever seen him, his jaw clenching and unclenching.
“Hello!” Jack chirped, bouncing slightly in his chair. Instead of Dean’s usual grunt and scowl, he jumped but nodded at the table before shuffling towards the coffee pot. The pair took the empty seats, immediately sipping the coffee Dean got them and ignored the worried glances between Sam and Jack.
“Hey guys,” Sam tried gently. “Is everything alright?”
“Never better,” Dean mumbled, busying his mouth with coffee again.
“Cas?” Jack whispered, his blue eyes huge and pleading.
“Hello Jack,” Cas hummed, giving Jack a tight smile. Cas dropped his head again, absently scratching at the stubble on his cheek. The kitchen fell into a tense silence as both Dean and Cas avoided eye contact, even with each other; Dean caved first, throwing back the rest of his coffee and standing abruptly.
“Who wants breakfast?” Dean’s movements were jerky and tense as he searched the fridge for something to make for breakfast. Sam turned to Cas, hoping his friend noticed his brother’s odd behavior, but his blood ran cold; Cas had a faraway look in his eyes, staring at the wall behind Jack’s head, ignoring his son’s attempts at grabbing his attention.
Whatever was wrong with his brother and his best friend was more nerve racking than anything he’d ever faced, and Sam had no idea how to fix it.
After the first incident, Sam noticed Dean and Cas still waking up earlier than he thought possible for either of them, but neither looked that shaken up again. Despite their attempts to stomp down whatever was bothering them, Sam knew his brother and his best friend well enough to recognize the haunted look in their eyes each morning.
The first few times it happened, Dean and Cas would disappear somewhere deep in the bunker for a few hours, and when they surfaced again, they would seem mostly back to normal. Well, until the sun started to set. Sam ached to press the topic when he noticed the pattern- the sun would set, then Dean and Cas steadily grew more fidgety. He couldn’t bite his tongue anymore when Jack started to notice. Roughly a week into their strained dance around the hunter and ex-angel, Jack and Sam decided enough was enough.
The keys of Sam’s laptop clicked loudly in the silent library as Jack flicked through a lore book next to him. Lunch had come and gone without any sightings of Dean or Cas since breakfast and Sam’s anxiety was vibrating through every muscle in his body. Footsteps thumped against the floor, drawing Jack and Sam’s attention to the door at the back of the library. Dean appeared with Cas not far behind, both of their eyes downcast as they shuffled into the room, dropping into chairs a table away.
“Hey guys,” Sam greeted, pointedly keeping his eyes on his computer screen.
“Hello,” Jack chirped, his eyes crinkling with the stretch of his smile. Dean grunted in acknowledgment, and Cas gave them a barely-there smile before dropping his head again. Sam’s eyes flickered across his brother’s face first, his stomach clenching at his haggard state. Dean’s cheeks were missing the natural pink tint, making his face look longer and thinner; dark bags outlined the curve of his dull, unfocused eyes. Sam shifted his gaze to Cas, who didn’t look much better; Cas’ beard had grown in thick, and he looked drawn, somehow paler than Dean.
Jack shifted in his seat, drawing Sam’s attention away from the stretching silence; he wanted to hurl when he caught the film of tears pooling in Jack’s eyes. He looked so helpless and lost that Sam could barely contain his own despair that surged up.
“Okay, enough,” Sam barked, slamming his hands down on the table. Dean and Cas jumped in their chair, immediately snapping to attention, sitting up straighter in their seats. “What the fuck is going on with you two?”
“Nothing,” Dean grumbled, tightly crossing his arms over his chest.
“That’s bullshit, and you know it,” Sam challenged. “Have you looked in a mirror recently, Dean? If I didn’t know any better, I’d think you and Cas were on your death beds.” Jack sucked in a pained breath, muffling a broken whimper with his hand. “You’re scaring Jack and, frankly, me too.”
“I’m sorry,” Cas spoke up, flickering his eyes between Jack and Sam.
“What the hell is going,” Sam repeated, sighing heavily, wiping a hand over his face. Dean sucked in a deep breath, ducking his head to force Cas to meet his eyes; the pair held eye contact for nearly a minute before Dean buckled, his face falling. Cas pushed himself to his feet, brushing nervous hands down the front of his t-shirt before reaching for Dean. Sam’s brows shot up to his hairline when Dean gently took Cas’ hand, threading their fingers together before standing. Cas led Dean to the empty chairs across from Sam and Jack, giving the hunter a tight smile before gracefully sliding into an empty chair; Dean forced air through his nose, staring down at Cas with a pained look before dropping into his chair.
Cas folded his hand on the table, more to comforting himself than to appear formal. “It appears that Dean and I have been suffering from incessant nightmares.”
“Nightmares?” Sam blurted, blinking at the ex-angel.
“Yeah, Sammy, nightmares,” Dean snapped, narrowing his eyes at his brother.
“What kind of nightmares?” Jack cut in, tilting his head. Dean and Cas shared another forlorn look before Cas jerked his head once, wiggling in his chair before he spoke.
“It’s been happening every night….”
The long corridors, splashed with red emergency lights, reminded Castiel of the bunker, but he could tell he was nowhere near his found home. Something seemed different.
Wrong.
It was so quiet that his pulse was deafening, adding to the agonizing throb at the back of his mind. Castiel could feel something like a presence poking at his brain. A tugging and twisting at his thoughts, molding them into something ominous. He gritted his teeth, fighting tooth and nail to keep control over whatever was trying to use him as a puppet.
Then the footsteps started.
Castiel snapped to attention, squaring his shoulders, rising to his full height, ready to face down anything. He quickly recognized the cool metal of a gun as his fingers brushed past what he assumed was a holster on his right thigh. A weight settled in his left, his fingers flexing around the knife. Castiel brought the knife closer, inspecting the way the metal twinkled in the red light blanketing it, a dark smirk spreading across his face.
He snapped into action when thundering footsteps rounded the corner, moving with the grace of a perfected dance. Castiel didn’t see faces as he sliced at whatever flesh he could reach; he had no idea who these people were or why they were there. And the worst part was, he didn’t care. His thoughts and actions grew more crazed, and to his own dismay, he was thriving off it. Unhinged laughter burst from his lips, the sound echoing off the walls, making him sound far beyond insane. Castiel spun to a smooth stop, tilting his head as he studied the dark pools at his feet with interest.
Castiel sensed his presence before he saw him. Lifting his head slowly, Castiel’s eyes raked over the figure at the mouth of the hall. A wild, carnal feeling bloomed low in his stomach. The figure strolled closer, unbothered by the bodies littering the floor. He stopped less than a foot in front of Castiel, blood encasing the soles of his boots. The crimson light made his cheekbones look sharper and his jawline more pronounced despite the days of stubble.
Dean’s green eyes blazed under the light as something deliciously wicked danced behind them, drawing Castiel closer. A twisted smile stretched Dean’s face in a way that should’ve terrified Castiel, but instead, he mirrored it. He could feel himself spiraling out of control, teetering on the edge of insanity, slowly being nudged forward by the voices bouncing off the inside of his skull.
“Look at you,” Dean purred, swaying closer. Now Castiel could see the congealing blood splattered across Dean’s face and in his hair. A tiny, almost buried, part of his brain knew he should’ve been disgusted, but the overwhelming urge to swipe his fingers through it won.
“Beautiful,” Castiel whispered, dragging his thumb through the blood, spreading it along Dean’s cheekbone. His wide eyes followed the movement, his tongue involuntarily swiping hungrily across his lips.
A scream tore through the still air, but neither man flinched; Dean’s devilish smile only grew. “We aren’t done yet.”
“Lead the way,” Castiel chuckled darkly, giddy at the idea of more bloodshed.
The library felt empty without the loll of Cas’ voice filling the air. Sam, Jack, and Dean sported various looks while Cas ducked his head, curling in on himself. Sam and Jack shifted between worry and revulsion, avoiding Cas’ eyes. Dean, on the other hand, somehow looked paler than he did a few minutes ago and he stared horrified at Cas.
“I-I’m…” -Cas shivered violently, wrapping his arms around himself- “mortified. It’s been haunting me for days.”
“That’s your nightmare,” Dean gasped, his hands trembling on the table.
“…yes,” Cas whispered. “Please don’t-“
“That’s my nightmare,” Dean cut in. Cas’ head snapped up, his face falling and his eyes growing wider as he stared into Dean’s eyes.
“What,” Cas breathed.
“I’ve been having a similar nightmare,” Dean whispered, swallowing thickly. “The only difference is my nightmares from my point of view.”
“We’re…how,” Cas faltered, his breath hitching, his shoulders shaking around sobs.
Dean twisted his and Cas’ chairs, so they were facing each other before pulling Cas onto his lap. “Shh, relax.” Cas collapsed onto Dean, burying his face into Dean’s shoulder, hiding his tear-stained face as the older Winchester tried to soothe him and hold back his own tears.
“Dean,” Sam whispered, drawing his brother’s attention. Dean’s eyes were huge, red-rimmed, and bulging with terror.
“Help,” is all Dean croaked, hiding his face in Cas’ shaking shoulders.
Jack wasn’t Lucifer’s first kid. He was a backup plan. Lucifer knocked someone else up and this kid? Well, she’s much more inclined to her father, until someone else entered the picture.
Nephilim In Love (Ongoing) - Sequel to T.O.N
After what happened with Lucifer, Y/N is no longer the person she once was. She doesn’t want to use her powers. But she’s forced to when her only family is threatened, leaving a certain angel to slowly fall in love.
What if there is a world where there’s a bad Dean Winchester and all Dean has to do is to get Michael into the other Dean and then kill them both? It wouldn’t be difficult, because our Dean puts up a fight and that’s something Michael doesn’t like, so I guess he could eventually jump into his other “perfect vessel” who’s not only HIS vessel, but is also dark and evil. It would make things much easier, in Michael’s eyes.
I mean, in 14x10 Michael said:
God – Chuck – is a writer, and like all writers, He churns out draft after draft. My world? This world? Nothing but failed drafts. And when He realizes that they’re flawed, He moves on and tries again
We know there are other universes. AU!Michael comes from a world where Dean Winchester doesn’t exist only to posses his “perfect vessel” and destroy Dean’s world. He will then move on to other worlds to try and catch God - or at least get his attention.
We know there are alter egos, like AU!Castiel and Dark!Kaia, who killed her “original” self and still stayed alive, so there’s no tricks like “if you kill your alter ago, you’ll die yourself”. As far as I recall, dark!Kaia doesn’t come from the same world AU!Michael does, so there must be at least one world in which Dark!Dean exists. They never dismissed the idea.
What if the book Billie gave Dean says “Kill yourself”, and of course they won’t reveal the solution because we have to suffer in drama first, but it would eventually turn out it doesn’t have to be your original self - aka loophole.
It would make beautiful sense on the meta level - Dean killing his bad self, everything he despises and doesn’t want to be. It would also make sense why they show Michael in Dean’s vessel even in Dean’s mind, whereas they showed Mark inside Cas’ mind and Tahmoh in Sam’s mind AND why Dean talked to the mirror - one, to make sure it’s just him and not Michael, but what if it’s also some kind of foreshadowing in which Sam and Dean will have to guess which Dean is which?
