Two steps into the library Dean was tackled by Jack. It hurt and he groaned, feeling every bruise he'd acquired.

"Dean!" Jack yelled, he was all blond hair and enthusiasm. Like the whole kidnapping thing was a random, unfortunate misadventure and he was over it already.

"You're going to have to be more specific Jack. We have two of those now." Cas laughed.

Jack grinned at him over Dean's shoulder as they embraced. The hug lasted longer than was comfortable but he let it slide, just so relieved they had him back. Pulling away he walked to Cas and embraced him. It was hard and desperate.

Grasping the angels' shoulders he resisted the urge to shake him. "What were you thinking? You could have been killed" Dean scolded. He felt sick, dizzy with relief. They were all back in one piece, now they just had to get home.
Cas looked into his eyes and was relieved, this was something normal for them both.

"I'm sorry Dean. I had to go. I felt Jack hurting... Then they caught me as soon as I appeared and I couldn't get out."

"Just don't do it again, okay? Jesus Cas... anything could have…" He stepped back with a deep huff, "...just take me with you next time?"

"Here." Cas nodded then reached out, a cool hand cupping Dean's jaw. The touch fixed all of the fight injuries.

"Thanks, Cas." He felt better and rolled his shoulders.

Dean turned to Jack. "Jack, you okay?" He asked checking for damage one last time. The penetrating gaze examined his neck looking for marks. The Nephilim wore a blue shirt and jeans and Dean felt the rage rising at the smattering of blood on his collar.

"I'm fine Dean, a little weak from the grace thing but that will come back." Jack frowned, "Why do people keep taking my grace?"

Dean smiled tightly at Jack's innocent question, "You scare them." Dean leaned against the wall arms folded. "You'll be invincible one day and it freaks them out."

Jack seemed sad but thoughtful and whispered, "Do I freak you out, Dean?"

Dean's brow raised, "Your power is kinda... crazy, but no Jack you don't scare me." He winked to reassure him further.

Jack grinned but it faltered, "That's good Dean, but sometimes I scare me."

Dean changed the subject, not liking the worry on Jack's face, "How did you know it was me when I came in?"

"I can see you." Jack squinted then shrugged. That explained everything...Angels.

D2 and Sam entered while they were talking, then Cas-two flashed in. Everyone looked healthier than on the drive home.

"Guy's, this is Jack." The introduction was followed by a round of 'Hey' and 'Hi's'.

"So you have superpowers?" D2 asked and Cas-two and Sam rolled their eyes.

"He's pretty much indestructible at full power." Dean touched Jack's shoulder, radiating pride. Jack stood taller with it, grinning.

"Awesome," D2 replied as Cas two wrapped his arm around his waist.

Jack's eyes went wide, "What's happening?"

Dean looked at the direction Jack was staring. Shit. "Err…" and Dean realised he'd become used to it...when had that happened?

"We're married." D2 laughed and Jack grinned.

"Married…" he had his quizzical face on, "A party? Was there cake?"

Trust Jack, straight to good questions.

"Yes, there was cake. Would you like to see the pictures?" Cas-two added, taking an instant shine to the young man. Jack just had that effect on people. Jack nodded it was a touch too fast and he became dizzy.

Dean reached out to steady him. "Jack why don't you sit down for a bit, look at those pictures?" he prompted and gave Cas-two glance and he nodded in understanding, Jack should take it easy.

Cas moved over to Dean as Cas-two sat with their charge.

"I'm so glad to have him back." Cas smiled and Dean returned it then replied,

"I know, I feel like I can breathe again."

"You know he's going to tell Sam when we get back?" Cas added and Dean paled. Jesus, he'd never hear the end of it. Though Sam's face would be a picture, yeah it might just be worth it.

"Dean, are you okay?" Cas assaulted him with that look. The 'I see you're broken and I am making you acknowledge it' look.

"I'm good Cas," Dean replied softly and with so much care, it made Cas blush. If there was one thing this reality was teaching Dean it was to be grateful for the Angel at his side. It was okay to be loved and love in return. ...as friends. ...Stupid universe.

They stood in silence looking at each other. It should have been weird, but it wasn't. Cas searched his face for a lie but seem satisfied Dean was being honest.

"Good. I have to tell you something…" Cas started, "I was trying to find the right time but I don't know if there is one…"

"Spit it out Cas," Dean whispered it and smiled. "Whatever it is, I'll deal."

Cas nodded and took a breath, "I've been watching you sleep...I couldn't leave you alone."

Dean grinned and met Cas gaze, "I know Cas. You're not as subtle as you think you are."

Cas looked sheepish and decided the floor was very interesting. "I didn't want you to have the nightmares."

Placing his hand on the Angel's shoulder he smiled again, "I know, it helps." he swallowed hard, "Thank you."

Cas looked up at him then, the tone catching his attention. The look was full of love and surprise. Dean continued, "For everything."

Dean didn't think that he'd said that before now and he could have kicked himself. Cas did everything for him.

"It's okay Dean. You're my friend."

"I am Cas."

They stood and watched Jack's face light up, he asked who everyone was in the pictures. The random knowledge thing happened again when Cas-two explained weddings and customs. Jack was both wise and so innocent; it was a wonder to watch.

They smiled and laughed at him as he asked inane things that excited him.

Dean's favorite was "Why is the food so small?" and Cas-two laughed, "They're Canapés Jack."

It didn't clarify anything for him and he frowned in confusion. Dean laughed, "They like to starve people at weddings." he joked and Jack whipped his head to stare at Cas-two who scowled at Dean as he chuckled.

"Dean's joking. It's things for people to eat while everything is settling down and then you have a meal later."

Jack smiled, relieved "Oh good."

The joke was on Dean a few seconds later when Jack turned, asking, "So are you and Castiel getting married, Dean? Can I come?"

Dean's laugh turned into a cough and he was choking. Cas-two became hysterical. It was side-splitting laughter that had tears running down his face. Cas was staring at his son with wide eyes and an open mouth.

"What? Did I say something wrong? Jack asked, worried. None of them could speak to reassure the Nephilim. When D2 walked over to see what as happening it made things worse when Jack recounted the story. Cas-two laughed harder and then D2 joined him. Dean face-palmed as the coughing ebbed and Cas stared.

Eventually, Cas found his words, "Jack, Dean and I we... that's, no. It's not the same." he smiled.

Jack had his thoughtful face on like his brain was processing. He got this wrinkle between his eyes and a confused squint as he considered what to say next.

"...but, Dean, you love Castiel." he looked at Dean with wide eyes, "I don't understand."

Dean wanted the world to swallow him up, why were these questions aimed at him and not Cas?

"Well, it's different." Cas-two started, and Cas picked it up, "Dean and I are friends."

"I...what's the difference?" Jack asked, "Are you, two friends?" He addressed Cas-two and D2.

"Yeah but it's more than that," D2 replied with kindness in his tone.

"More? How?" Jack asked and Dean gave Cas-two and D2 a warning glare, a let's 'keep it clean' glare.

"Well we sleep in the same bed, we share everything…" Cas-two added looking at Cas and he nodded. That was an acceptable compromise.

Jack thought again, "Share what?"

"Things, feelings...we kiss and stuff." Cas-two looked at Jack. "Your Dean and Cas don't do that."

Jack mulled it over, "So, to be more than friends, you have to kiss each other?"

Cas-two nodded and then thought about it, "Well, no actually...this is complicated."

Jack frowned, "I'm confused."

"Romantic love is different from friend love Jack," Cas added.

"How?" Jack asked again seeking clarification. "The only thing that seems different, that you and Dean don't do, is kiss…"

"And sleep together," Cas-two added reminding the Nephilim.

Jack shook his head, "No. They do that." He corrected himself, "...did, until Dean got better, now Cas just stands in his room."

D2 and Cas-two turned their heads comically slow to peer at their doppelgangers.

Dean cringed, this conversation needed to end, like now.

"For the nightmares…" he growled but it had no bite.

"Right..." D2 snorted suppressing a laugh.

Jack smiled, still confused.

"There's no difference." Sam interrupted. Having stood on the fringes giggling to himself at the level of awkward brewing in the room.

Everyone went slack-jawed.

"Love is love. Friendship is love. You choose to commit romantically to one or more people but you start as friends. That means building a life together. Some people have a physical closeness like kissing and some don't. Some just love each other, some people marry and others don't. It depends on what people want to do. Dean and Cas got married because they wanted too, they wanted to add that commitment. They made it more than friends"

Jack considered and then smiled, "I understand now, thank you, Sam." He thought again and added, "So Dad and Dean might stay friends forever?"

Sam grinned and nodded, "Yeah, would you be okay with that?"

Jack smiled and nodded, "Yeah, Dean and Sam are my family. Castiel is my dad. Dean acts like him so that like having two Dads… and Sam treats me like he treats Dean so that like having a brother."

Dean's heart fluttered in his chest. When did the kid get so perceptive? Jack had basically called him his dad, something twisted behind his ribs. Lost for words he glanced at Cas who smiled. Relief flooded Dean now that the conversation was over.

Then Jack added, "I would like being a Best-man though, you know just in case…"

They all laughed. Jack sat smiling, not understanding why everyone was so happy but enjoying it anyway.

Dean turned to Cas once it fizzled out and asked casually, "When can we get out of here?"

Cas looked at him and frowned, "Not until tomorrow. Sam will be placing the sigil here on the wall at 12:00." The Angel pointed to emphasise.

"So, we have what, a day to kill?" Dean sighed, "Great, just great."

Dean was starting to feel exhausted and sagged against the wall.

Both of the Cas' tilted their heads at the same time and Jack's eyes glowed gold.

"We have a problem." Jack hissed.

Something like a bomb hit the bunker, they all ducked.

"What the hell was that?" The Dean's yelled together.

"Angels." The Cas' replied together.

It was starting to feel like there was a perpetual echo in here. No dust fell so they hadn't been physically hit.

They all stood and looked at the Cas', "Will someone explain what the hell is happening, please?" Dean shouted first, unable to hear over the ringing in his ears.

"They're coming for Jack." Cas-two started, "but we have-"

"- a spell surrounding the bunker protecting it from anyone who intends harm?" Cas finished.

"We need that…" Dean added, surprised and impressed. "How long will it hold?"

"Indefinitely," replied Sam.

"Cool, so we're good then?"

"Except we can't go anywhere because murderous Angels are surrounding us but yeah, we're good." Rolling his eyes, Sam moved to Cas-two and asked, "Can Anna help?"

"She'll try I'm sure, but it'll take time. Angel politics can be complex to negate. We should treat it like we're stuck here for the foreseeable future."

Their conversation was punctuated by loud bangs.

"That's fine right? We have food, water and we'll be leaving in less than twenty-four hours…"

"Yeah, we can wait it out and hope they don't find a way through."

There was a whoosh and Anna appeared.

The red-haired angel walked briskly to Cas-two. "Castiel."

"Anna, what is happening?"

"You must ward this place Castiel. Raziel is on the warpath. He seeks witches to destroy your protection. I pray he won't succeed or find a way to circumnavigate it, however-"

"- we should take precautions." He finished.

Nodding she turned to the rest of them, her tight fitting blue suit glinting under the lights.

"Ward and set up banishments. It will affect your angels but they can always return later."

"I can stop that," Jack added. They all turned to stare at him.

Cas-two spoke first, "You can prevent our banishment?"

"I think so." He turned to Cas who nodded and touched his chest. The trust was absolute. The Angel hissed as Jack pressed his hand over Cas's heart and both Dean's flinched.

"Jack are you sure…" as his eyes lit up like spotlights, Dean stopped, retreating back a few steps. That's still creepy, he thought. It was also badass.

Cas twitched and glowed gold as if the sun was trying to escape through his skin.

"Well, that's creepy," D2 commented, verbalising his thought. They both smiled together.

Cas' coughing fit interrupted their sniggers, "I feel, different."

Jack moved towards Cas-two and he took several steps backwards, wary.

"I won't harm you. You're my father, in any universe."

Cas-two face baulked in surprise and looked at his double who nodded. There was no difference to Jack, he had such an enormous capacity for love.

"Does it hurt?" he asked.

His counterpart considered the question, then replied, "a little, but it's like the atoms are being stretched to facilitate, more…"

"More?" D2 asked.

"I can't explain it. Just more..."

"Cas…" The noise which escaped his doppelganger was as close to a whine as Dean had ever heard.

"I'll be okay Dean." His tone held such depth and love that both Dean's felt it all the way to their toes. He frowned at the accompanying full body shudder. It was unexpected with a dollop of uncomfortable,

His Cas stared like he'd just done something interesting. 'Don't look at me like that Cas', the thought crept in as Dean took a hard look at the ceiling.

Another sun-like glow filled the room and Dean watched his double in curious side glances.

D2 looked, well... terrified. It was all in the eyes, that's where the emotions showed. The man's face was stoic but his eyes were freaking the fuck out. A few shudders later and Cas slumped a little into his husbands' arms.

"You were right, I feel...full."

"Anna, Is it? You too?" Jack offered, glancing at the Cas-two for confirmation that she was an ally.

"May I?" She queried with him at the same time and Cas-two nodded. Stepping forward Jack touched her and repeated the process.

"Awesome, all angels in the room are banish-proof. Let's get to work huh?" Dean turned, cut his palm and started drawing sigils on the wall.

They all followed, repeating the process throughout the bunker.

Once complete they were all exhausted and Sam decided to make dinner.

Anna went back to heaven and Dean went to his room for a nap, the emotional toll of the day was nipping at his heels. D2 and Cas-two agreed it would be a good time to get some rest and ventured off into their rooms. Jack and Cas stayed in the kitchen with Sam.

It seemed weird to remain so calm but there was literally nothing else to do.

Lying on a bed that wasn't as comfortable as his, Dean drifted into a fitful, light sleep.

The dream came in a flash, hard and fast. The Canadian Rockies, surrounded by snow and two naked, writhing bodies. He watched himself being taken by Castiel. The steaming, bubbling water of the hot tub lapped at his legs.

Cas sat in the water and it swirled around his waist, caressing his cock. Dean was in his lap, lowering his slick ass onto all that hard length. Suddenly, he was pulled into his body, no longer watching from the outside. Dean could feel every inch as it opened him wide, each stretch, and each warm push into his tight hole. Holy shit... His cock was so hard; it throbbed as the bubbles teased that delicate skin between his legs.

One hand was gripping the side, the other braced on Cas' muscular thigh. The feeling of hands on his skin had him panting. The angels' lips caressed the tender skin between his shoulder blades; it was pure ecstasy. His ass clenched as he took another inch. Oh god... the pressure was all-consuming as his taught sphincter consumed the impressive length. His hips met Cas' lap, he felt so full, fuck.

Dean's cock throbbed with need and Cas took it in his hand and squeezed. Oh my god, he growled wordlessly into the cold, dark night. He wasn't in control as he moved, fucking himself until he was nothing but pure sexual need.

The angel moaned and relaxed, leaning into him, skin on skin. It made everything twitch and shudder. His skin was on fire, so sensitive and overwhelmed with feeling it hurt.

"Fuck." He moaned into the damp air as sweat rolled from his skin to the water below.

Dean was so close, it felt so good. The panting and gasping increased as Cas' hands moved and dug into his hips. Holy fuck... he loved the strength in those gorgeous hands. Loved knowing that Cas could make him do anything he wanted because he was just that strong. Though he wouldn't, Dean was safe, always. The rhythm, the angle were both perfect and hit all those sensitive, exquisite places deep inside his ass.

Cas' grip got firmer and Dean twitched again. Oh... so close. He took his cock and squeezed until the throbbing was all consuming. The ecstasy flowed through him as his heart raced and Cas moaned, it drowned everything out. The orgasm landed in a tsunami of rapture. Hot cum flowed over his fingers he bucked and writhed on Cas' lap.

Cas twitched, then moaned and throbbed his load into Dean's tight ass. The warmth rolled through him, wave after wave; he came harder. The euphoria flooded his body, drowning his thoughts. For what felt like ever, he let himself feel it all. The man at his back, the warm wet satisfaction spreading through him and the love radiating from Cas. He just rested and breathed, completely at peace.

Once the feeling returned to his legs he slid from Cas's lap into a heap in the water.

The pulsing aftershocks shook him as the foam caressed his sensitive cock. Yeah, Dean could get used to this. Cas lent into his shoulder and Dean held him. There was a small difference in height but the fit was perfect.

Dean looked up at the clear, cold night sky that was full of stars and felt safe. He felt whole. The hot water caressed his legs and the cold winter air wrapped around everything else. The contrast was amazing. The night air smelled of pine and chlorine. Nothing moved and the only sound was of breathing and bubbles.

Then Jack's voice pierced his bliss.
