So, apparently I've gone over some copy and paste limit or something? Woops! I have uploaded a lot recently, I guess. I just wrote this chapter and it's nearly 1am so apologies for any typos. I have a feeling when people have read this chapter, they're not going to like me very much. I didn't split this chapter either, so there's just an epilogue left, until the final story.

Dean woke up feeling stiff and groggy, and slightly sweaty where another naked body was pressed against his. It took a few moments for him to remember that he'd spent the entire evening with Castiel, flashing between different countries, culminating in them sleeping together - for the third time that evening - when they got home.

And like every other damn time, Dean felt a deep sense of shame. Not for sleeping with Castiel per ce, but for getting together with a dude. For corrupting his friend. For - oh, God - for actually giving the angel a blow job. Castiel hadn't complained, he seemed to be okay with it, and at the time Dean was game for it, but now? Now he couldn't believe he'd been so brazen, so unafraid to go there with Castiel.

It was the same fight he had with himself all the time. Yes, he cared about Castiel, and he was proud that they seemed to be raising their kid together okay. Castiel was confiding in him a lot more, but at the same time, the whole situation still felt weird.

'Dean? Are you awake?' Castiel asked softly, running his fingernails through Dean's hair. Dean closed his eyes, enjoying the sensation. He was glad he'd taught the angel to do that. He moved his head backwards slightly, into Castiel's touch. Maybe he was being a total girl and over thinking it. Maybe he just had to put his doubts in a little box in his head and never go there again. Because Castiel seemed to really want him.

'Mmm, I'm up.'

'Your eyes are closed.'

'Yeah. Keep doing that.'

Castiel kissed him, just by his ear, still scratching along his head. Dean opened his eyes lazily, grabbing Castiel's chin and pulling him closer, kissing him softly. Maybe it wasn't so bad, being in … a relationship with your best friend. Especially when he did that thing with his tongue. Like he was rolling an r in Dean's mouth. Castiel might be an angel, but he definitely took tips from the Pizza Man.

'Cas,' Dean breathed as Castiel started kissing along his neck this time. 'We should go check on Siobhan. Sam probably wants a break from her, by now. We can do this later.'

Castiel placed a final kiss on Dean's chest.

'That's fine,' he announced, and climbed out of the bed, pausing at the edge of the mattress. 'Dean? What do I do about clothes? I don't think Sam would want to see me like this, and I left my suit in the room Sam said I should change in.'

Dean sat up, and climbed out of the bed wordlessly, heading to his dresser and pulling out two pairs of boxers, one he threw to Castiel and one he slipped on himself.

'I'll get you a shirt too, but your jeans are fine,' Dean nodded to the pile of clothes they'd removed in haste the night before. Castiel nodded, and dug through the pile until he located his jeans, not seeing Dean wincing as he surveyed the mess. Did he really leave their clothes like that the night before? Did Castiel? Neither of them were messy. He guessed they must have just been really into each other the night before. He grabbed a black tee and a plaid shirt and passed them to Castiel, who smiled gratefully before pulling them on, while Dean grabbed some clothes for himself. When they were both dressed, Dean walked passed Castiel, kissing him briefly on the shoulder, and headed out of the room, knocking on Siobhan's bedroom door. Castiel waved a hand at the remaining clothes on Dean's bedroom floor, and they jumped into his laundry basket. Once he was satisfied, he joined Dean as he pushed Siobhan's bedroom door open. Her bed was empty, and the cushions and blanket were back on her little sofa. She and Sam were obviously already up and about.

Dean and Castiel found them sitting opposite each other at the table in the kitchen, bent over a jigsaw puzzle and chewing on slices of toast. They barely looked up as Dean headed for the coffee pot and Castiel sat beside Siobhan, picking up a piece of sky and putting it in place as Siobhan frowned at two pieces of sun. Sam broke the silence.

'So, how was the date?'

'Fine.' Dean grunted, and slurped a big mouthful of coffee, relishing the flavour and swallowing with a sigh.

'What did you do, get drunk at a bar?' Sam smirked. Castiel looked up from the skyline in the picture that he had nearly completed already.

'No, Sam, we didn't go to a bar.'

'Leave it, Sammy.' Dean grunted, pouring another coffee and walking over to join them all, kissing Siobhan on the top of her head as he walked passed to sit beside Sam.

'Did you go park the Impala in a field and talk?'

'Sammy, you wouldn't believe me if I-'

'Dean and I enjoyed a trip around Europe.' Castiel interrupted, handing Siobhan an easy piece to add to the puzzle as Sam choked on a half-chewed mouthful of toast.

'Europe? You were only gone for a few hours.'

'Angel travel. And angel time,' Dean spoke into his coffee cup.

'Huh. Did you get me anything?'

'It was a date,' Dean reminded him as he finished his second cup of coffee.

'Dean, you specifically took me into those tourist shops to get small gifts for Siobhan and Sam.' Castiel reminded him, slipping an arm around Siobhan as she reached up and kissed his cheek. Dean smirked up at him.

'Yeah, but I wanted him to squirm.'

Castiel frowned, obviously not understanding Dean's desire to tease his brother.

'I'll go get them,' Castiel announced, standing up from his seat, and then pausing, not moving an inch, as Siobhan grabbed her head and started making a pitiful mewing sound. Dean was up and around the table in seconds, crouching by his daughter and asking her what was wrong.

'The angels are talking,' Castiel said through gritted teeth.

'What're they saying?' Sam asked, feeling bad that he couldn't approach Siobhan and comfort her the way Dean was.

'They're shouting! They're hurting my head!' Siobhan sobbed, burying her face into Dean's chest, still clutching her ears.

'Balthazar has told other angels about her. They're threatening to come here by whatever means they can, and remove the threat.' Castiel said with distaste.

'The bunker's the safest place to be,' Sam pointed out.

'And you don't think those dicks wouldn't try whatever they could to get to her?' Dean shot back, oblivious to Castiel's brief look of disappointment as Dean once again referred to angels as dicks.

'So what do you suggest?' Sam asked.

'We make sure the bunker's shut down, as much as possible. I'll watch the front door, you check the garage. There isn't anywhere else they could get in, is there? We'll get Bear to watch over Siobhan while we make sure they can't get in. We've got enough angel blades, right?'

Dean, as ever, took charge without considering the issue. Siobhan's eyes grew large and round at the mention of blades, and Castiel left the room, only to return a few moments later with a handful of blades and Bear tucked under his armpit.

'Bear understands the seriousness of the situation. She'll make sure Siobhan stays in the kitchen fixing the broken picture while we ensure this place is protected. Here,' Castiel handed two blades each to Sam and Dean, and keeping two for himself, he eased Bear out of his armpit and placed her on the table, patting her head. He bestowed a small kiss on Siobhan's cheek, and Dean did the same soon after, before they left the kitchen, closing the door behind them. Sam headed off to the garage, as Dean strode through the meeting room, climbing the metal stairs three at a time and testing the door.

'Cas? Is this door angel-proof?' Dean growled. Castiel shook his head. 'Think we got enough time to write some sigils?'

If we do it quickly. If we need to, we can always prepare the blood spell.'

'Okay, you do the sigils.' Dean slit his hand open with one of his angel blades and started daubing the walls as Castiel grabbed a nearby spray can and started painting on the walls, across the door. It was trapping Castiel in, but it was keeping their daughter safe.

'Do you think Sam is doing this as well? Dean asked as he deepened the cut, adding more blood.

'It's Sam, he's a very intelligent, practical person. I'm sure he'd take whichever precautions necessary.' Castiel stood back and admired his handiwork. 'We'll be fully protected now.'

'Good. Think you could heal my hand?' Dean asked, holding out the one he'd cut. Castiel took it gently in his own and lifted it to his lips, kissing the wound gently, feeling Dean's hand heal under his mouth. He looked up and saw Dean staring at him, his Adam's apple quivering and lips slightly parted. After a few prolonged moments of eye contact, Dean cleared his throat, and looked around, withdrawing his hand.

'Huh, um, we should get ready.' He breathed out deeply and turned to look at the door, critiquing Castiel's handiwork. A few tense minutes passed with nothing occurring, and then the ground started shaking, and plaster dust began falling from the ceiling. Dean ducked, and found his head tucked next to Castiel's, and Castiel's wings an invisible barrier above them.

'Are you okay?' Castiel asked breathlessly.

'I'm fine, but what about Siobhan? Bear can't know what to do in an earthquake! I'll stay here in case the angels manage to break through, you go make them hide under the table, okay?'

Castiel nodded, and gave Dean the briefest peck on the lips before running down the trembling staircase, and practically flying through the bunker to the kitchen. Dean readied himself in front of the front door, as the shaking stopped. He listened intently, in case something was happening outside, some new plan of the angels. He clearly heard it, a minute later, when Castiel shouted his name, the panic in his voice evident. Dean gave up his defensive position and ran down the stairs himself, following the sound of Castiel's voice. He met Sam in the passageway, who looked just as freaked out.

'I wrote angel-proofing sigils on the walls-' Sam forced out as they hurried along.

'Cas did the same upstairs, there's a blood spell up there too, just in case.'

'Where's Cas gone?'

'Kitchen.'

They pounded the hallways together, until they reached the kitchen, where Castiel was peering into the cupboards.

'Cas?' Dean asked, his eyes scanning the room. The puzzle, half-completed. A slice of toast with three small bite marks in it. And absolutely no sign of their daughter. 'Where's Siobhan?'

'I thought she might be hiding in one of these, but it doesn't seem to be the case.'

'Shit. Okay, spread out, I'll check her room, Sam, you check mine, Cas, TV room. We'll work through until we find her, okay?'

They spent hours overturning the bunker, and still couldn't find Siobhan or Bear. Eventually, they all walked back into the meeting room, feeling defeated.

'We need a new plan,' Sam greeted his increasingly angry brother and the frustrated angel. 'She can't have gone far, but we can't do anything until we go out there and lie to anyone gathered. Tell them there's no nephilim here, play dumb, act like Balthazar was starting his usual crap. As soon as they leave, we can be more thorough, coax her out with promises, whatever we need to.'

Castiel looked at Dean expectantly, and Dean shrugged back at him.

'It's the best plan we've got. She might come out from wherever she's gone if she knows there's no threat. Maybe she's gone invisible.'

A muscle tensed in Castiel's jaw, but he didn't respond. Dean led the way to the front door, and Sam stepped out first, walking into the weak sunlight that dappled through the trees. He paused a few steps away from the front of the bunker, holding a hand out to stop Dean from going further. They both scanned the area in front of them as Castiel caught up, taking in the newly made crater and the blast marks from the soot that cut through it. And in the centre of the crater, in the hollowest part, there was a small, slightly charred lump.

Sam turned around, holding his brother's chest as Castiel crouched at the edge of the crater.

'Sam,' Dean's voice was murderous.

'It's Bear's arm.' Castiel said quietly. Dean began trying to walk forwards, into the crater, and Sam fought to keep him back.

'What the fuck happened? How did Bear get out here? Siobhan? SIOBHAN!'
