Sam and Dean hastily "excuse me-ed" and "sorry-ed" their way to the front of the crowd. Both ground floor windows on the front of the little house had been smashed and the front door torn from its hinges. Frank was in the front garden in a faded blue dressing gown, slippers and striped pyjamas, leaning on a wooden walking stick and wagging a finger in the face of some poor police officer. He's face was slowly turning an impressive shade of purple as he yelled about "terrible service" and "couldn't protect a bloody ferret" along with "what if it had been in my bedroom? I could have met the same fate as my poor mantelpiece…"

Sure enough, the demolished ex-mantelpiece and two separate halves of an armchair could clearly be seen through the broken living room window. Deep gouge marks (which may or may not have been inflicted by claws) that severely defaced the wallpaper could also be seen.

"I suppose FBI badges won't work here?" Dean said.

Sam looked at him.

"Right…stupid question. Think the doctor knows about this?"

"Oh I'm sure of it," Sam said. He was looking past Dean at something behind him. "I'm also sure that we have a situation."

Dean turned round and his stomach plummeted at the sight a few feet before him. The doctor was there, deep in conversation with none other than Cas.

"Ok…" Dean said softly, taking Sam by the arm and slowly turning his back to the pair. "They haven't seen us yet, if we just quietly head for the-"

"Oi! Winchesters! Over here!"

Sam and Dean simultaneously groaned quietly then put on the most sincere smiles they could muster, turned round and approached the doctor and the suspicious looking angel.

"Sam and Dean Winchester, this is Castiel the angel. I assume you're familiar with angels?"

"You could say that," Dean said, avoiding eye contact with Cas.

"Well he's been helping me out. Kept the creatures away as I did various scans of the egg to find out what's taken up residence on the beach. They're Parums, swamp dwelling reptilian creatures from the planet Saturnyne."

Dean looked at Sam. "I told you it was aliens!"

Sam rolled his eyes and turned to the doctor. "What are they doing on Earth?"

"Their planet fell through a crack in space and time."

"Of course it did," Sam muttered. The doctor ignored him.

"The crack consumed the planet's skies, causing its dominant species to flee. The Parums must have remained, able to survive in the remaining swamps. I can only assume these ones fell through the crack, landed here and now want to get home."

"So that planet in the sky…"

"Saturnyne," the doctor nodded. "Also brought here by the huge amount of power emanating from the crack. It can't stay here though. As soon as we get those creatures home, I'm gonna have to move it."

Dean looked at him in shock. "You can move whole planets?!"

"Of course I can," the doctor said dismissively. "Anyway, I'm off to do some more poking around, see if I can find out where the Parums are hiding. Coming anyone?"

"If it's all the same to you doctor," Cas said, before either of the brothers could say anything. "I would rather like to spend some time with these two…you know, get to know them…"

"An excellent idea!" the doctor said brightly, unaware of the cold glare Cas was giving the increasingly uncomfortable looking Dean and Sam. "Always good to get to know your co-workers. I'll see you all around then, cheery bye!" He strolled off, leaving an awkward silence behind him. After a moment, Dean spoke.

"Cas-"

"Not here," Cas said in a monotone. "Inside."

He strode off, Sam and Dean following like two scolded children.

They were soon back in Sam and Dean's room and Cas closed the door behind them before turning to look at them. Sam spoke first.

"Cas look-"

"You lied to me," Cas said softly, ignoring Sam and looking at Dean. "I was trying to do something nice for you and you repay me like this? Why, Dean?"

"Cas I'm sorry," Dean said. "But I need to be working. It's the only thing stopping me from going insane."

"But look at you!" Cas said angrily. "You look terrible! You work yourself too hard. Why can't you just take my advice and look after yourself for once?"

"Maybe my way of looking after myself is working a job!" Dean said, his anger rising to match Cas's. "And not taking orders from you like a foot soldier! Why do you even care what I get up to?"

"Because I care about you Dean! I worry about you all the time! Worry that one day I'm gonna come down to Earth and see that you've had a heart attack from all the stress you've put yourself under. But you're right, I don't know why I bother because you're clearly too selfish to think about how you're actions affect others."

There was an awkward silence after this outburst during which Dean tried his best to think up a smart reply but he couldn't. Instead, he felt his insides twist with guilt and sadness at what he'd put Cas through. There was no way he could admit that though.

Eventually, Sam broke the silence. "Cas I'm so sorry, we-"

"Forget it," Cas said, still glaring at Dean. "I can tell when I'm not wanted. I'll leave you alone now." There was a flutter of wings and he disappeared.

Late that night, Dean lay awake, unable to sleep. He hated to admit it, but Cas's words had had a profound effect on him, leaving him with overwhelming feelings of guilt and sadness at how hurt Cas had seemed. He'd been so busy trying to go behind Cas's back and do what he wanted to do that he hadn't given a single thought to Cas's reasoning behind his pushy nature. That day had made him realise that Cas really did care for him, a fact which made him feel happy and deeply ashamed of himself at the same time.

His thoughts were interrupted by a strange noise. It was a soft keening coming from outside. Maybe an animal was trapped somewhere? Frowning, he got out of bed and headed over to the window as quietly as possible so as not to wake Sam. Pushing the curtains open he was greeted by the sight of the beach lit up by moonlight. But it was what was on the beach that made him stare. Two huge lizards stood with their backs to him gazing at the strange planet in the sky, Saturnyne the doctor had called it. They reminded him of Komodo dragons except for a very significant difference – they had six legs instead of four.

"They often come out onto the beach at around this time of night."

Dean spun round to see Cas standing behind him, his expression unreadable. He swallowed back the emotional outburst that was waiting to happen.

"Why are they making that noise?" He asked instead.

Cas moved to stand beside him. "It's likely that it's an expression of distress and a desire to return home," he replied. "The doctor says that the Parums are sociable creatures that form strong bonds with other members of their species."

"So they're missing their friends," Dean said. "That's kinda sad."

"Mmm."

Dean looked sideways at Cas and was transfixed for a moment by his moonlit profile and deep blue eyes. He cleared his throat.

"Look, Cas, I'm really sorry I lied to you."

"It's fine Dean. I understand."

"You do?"

"Yes. I'm sorry I got so mad, I just wish you would let me help you."

Dean nodded. "I see that now. And I do need your help Cas. I need you to help me get by while I work and I…" he swallowed. Cas looked at him expectantly. "I just…need you."

Cas smiled and cupped Dean's face with one hand, stroking the bags under his eyes. "I need you too Dean," he said softly.

Dean's heart fluttered as Cas smiled at him and let his hand drop. "Get some sleep," Cas said.

Dean nodded. "What will you do?"

"I'll be watching over you, like I always am." He disappeared with a flutter of wings, leaving Dean feeling a lot more relaxed and happy than he was five minutes ago.

That's right bitches, Destiel is virtually canon in my stories.
