I'm back! I had a few requests about this relating to my Doctiel fic 'Four Times Castiel Visits The Doctor, And One Time Castiel Visits Him', and it was a cool idea, so I thought: Hey, why not? So, without further ado, I bring you 'Four Times Castiel Visits The Doctor, And One Time Castiel Visits Him: Revisit', being the same story but from the Doctor's point of view. Please drop me a review, and thank you!

Disclaimer: Doctor Who is not mine, Supernatural is not mine (though not for lack of wishing), any planet names are completely made up by me, and any resemblance they have to something else is entirely coincidental.

The first time the Doctor visits Castiel, it's more than a little bit odd, and the Doctor is intrigued.

The Doctor was busy. He was powering the TARDIS swiftly – and clumsily – through the Vortex, trying desperately to reach Kallapillia in time (when he'd left, the president was arguing fretfully with his parrot, a shoe was being thrown around, and absolutely none of it was his fault. Really.)

But then a distraction came along, as it always does, and the Doctor had to follow it, as he always does, and come on, he had a time machine, he could give himself this. Besides, it wasn't often his scanners picked up a celestial disturbance, who knows what it could be?

Mere seconds later, he arrived at his new destination. Forgetting to check the scanners for his location – he could just see River rolling her eyes – the Doctor stepped out of his TARDIS and looked around the grungy hotel room.

Three men were the only occupants, all reading thick, dusty tomes and looking bored out of their minds.

Well, two looked bored. The lone standing man seemed to have no expression at all. For some reason, something about him was intriguing. Though the tan trench coat and business suit implied 'simple human tax accountant', he exuded a quiet power, just not quite on the side of plain to let him fit in with his surroundings. It was… Interesting, to say the least.

Blinking himself out of his thoughts, the Doctor grinned at the two sitting humans staring at him in shock.

"Hello! Who might you be?" He asked, with a quick tweak to his bowtie.

'Bowties are cool.'

In a flash, the two men – 'brothers?' – were standing, and pointing polished guns – 'oh dear' – in his direction.

Grimacing, he put his hands up in surrender.

"Oh, not guns, I really hate guns."

"Who are you?" The shorter one demanded.

Ignoring the – loaded – weapons, the Doctor beamed again and skipped forward, outstretching a hand.

"I'm the Doctor! Hello!"

'Ooh, new people, I love new people! Exciting!'

The taller one spoke up, considerably calmer than the shorter with a raised eyebrow.

"Doctor… Who?"

"Just the Doctor! Do you mind lowering those guns? They," The Doctor coughed slightly and leaned forward, "They make me uncomfortable."

A gravelly voice spoke out in the room, immediately capturing the Doctor's attention and reminding him why he was here.

"You are not human."

'Perceptive! Ooh, interesting!'

"Nope!" The Doctor replied, bouncing over to him. "Time Lord actually, the last… But what are you?" Whipping out the sonic, the Doctor set the controls quickly and buzzed.

"What is that device?" The mysterious being questioned, sounding adorably confused.

"Sonic Screwdriver." The Time Lord smiled. "It scans things." Flicking up his trusty tool – 'Ooh, trusty tool, must use that more often' – he checked the results with interest. What he saw made him positively beam.

"Oh… You! You are amazing! An Angel! Really! Never thought I'd see the day! MUCH better than the Weeping Angels, I didn't want to blink for weeks!" Another scan brought back the same results, making the Doctor grin.

"What's your name?"

"Castiel." The creature – Angel – replied with a frown.

'I'm not being rude, am I? Where's Amy when I need her? Ooh, handshake! Humans do handshakes don't they? Do Angels do handshakes?' Deciding to just go with it, the Doctor stepped back and offered one hand.

"Pleasure to meet you, Castiel."

The Angel seemed hesitant in taking the offer – 'Handshake not a good idea?' – but eventually did. "Likewise."

'His eyes are really blue.' The Doctor marvelled. 'Angel thing perhaps? Interesting.'

"Will someone please tell me what the HELL is going on here?" It was the shorter one speaking that time. With a whirl and a bound, the Doctor was back at their side.

"Right, sorry! I'm the Doctor, alien, Time Lord, two hearts, time traveller, brilliant at cards," 'sometimes', he pointed at the TARDIS, "and that, is my TARDIS, Time And Relative Dimension In Space, a BEAUTY, if I may say so myself." He stroked the wood happily. "I saw a disturbance on the scanners, decided to pop in and check it out. I assume that was your celestial friend over there. Now, I didn't get either of your names, and could I also perhaps have the date, location, and the nearest store that will sell me a fez?" 'Fezzes are cool.'

After a while of expectant waiting, the taller man muttered, "What the Hell?"

Castiel stepped in swiftly to answer his questions, making the Doctor smile at him as he spoke.

"This is Sam and Dean Winchester; they are hunters of evil supernatural beings." 'Brothers, I knew it.' "It is the 6th of April, 2010, and we are in Massachusetts, America. I do not know where you may acquire a… Fez."

'Damn.'

"I can buy one somewhere else." 'Oh dear, didn't I have something to do? Oh! Kallapillia!'

"Well, wonderful meeting you, I really should be off. Got a dreadful problem concerning a parrot, a shoe, and the President. See you again Castiel, Sam, Dean." He nodded at them with a smile before jumping back in the TARDIS, setting the controls in a whiz of movement before he was on his way.

'I think I'll definitely be seeing you again, Castiel. You are a mystery.'

Buzzing lightly at having met an Angel, the Doctor ran off to save the world – again, with a glint in his eye and a smile on his lips.

The second time the Doctor visits, it's because he knew he would eventually, and come on, he really couldn't resist a mystery.

The Doctor had just finished dropping off his Ponds when he decided it was time. Sure, there was a case of giant hamsters that could potentially start eating flesh at any time, but they could wait a little longer, surely?

Castiel was reading at an old wooden desk when the Doctor found him. His presence wasn't hard to pick up, but it still took him a while.

'Hmm. I should find a way past that.'

"Castiel!" He smiled in greeting.

The Angel appeared not to have heard him, absorbed as he was in his book, as he startled at the Doctor's chirp.

"Doctor." Castiel replied, not unpleasantly.

Silence.

The Doctor didn't like silence.

Glancing at the books, the Time Lord hopped over to him with another smile playing on his lips.

"So, I see you've been looking me up."

'How amusing. He could have just asked.'

Castiel seemed to know that, as he quickly began, "I would have asked, but-"

The Doctor cut him off. "It's fine. Though next time, just call. I'll set the TARDIS to hear you." 'I can do that, can't I? Yes, I can do that. Speaking of my TARDIS…'

Talking about his old girl was something the Doctor loved to do, and that quickly lead onto things the books didn't mention about Time Lords, which, pleasantly, was another thing the Doctor liked to speak of, so winnings all around.

But eventually, the Time War came up.

The Doctor skipped over a few of the more grisly details, trying to stick to the facts.

His mind was wandering, back and back and back, to the horrors, the madness of the Time Lords, the terrible Nightmare Child…

And then there was a hand on his shoulder, and The Doctor looked up into caring blue eyes, and for some reason, somehow, that helped.

Eventually, he had to go however. Explaining quickly of the hamster situation – possibly at critical danger by now, oops – the Doctor stood to say goodbye.

They were awkward for a few seconds, but the Doctor never liked awkwardness.

So with a great grin, the Time Lord leaned forward and pulled Castiel into a hug.

'Wow, he's warm – Angel thing?'

"It was a pleasure talking to you again, Castiel. And don't forget to call if you ever need anything." While most people called him 'Cas', the Angel had said he was fine with Castiel is well, something the Doctor was pleased with.

'I like saying it. Castiel. Castiel. Cassssstiiiiieeeeelll. Cas, tiel. Castiel.'

"Likewise Doctor." 'Oops, bad Doctor, pay attention!' "I shall remember that."

The feeling of Castiel's arms around him was one the Doctor loved, but he really should sort out those hamsters, so with another exchanged smile and a leap into the TARDIS, the Time Lord left the Angel standing alone, while his old girl hummed and whirled him away.

The third time the Doctor 'pops in', it's because he hears Castiel's call, and the rest of it's a bit of a white blur, actually.

The Doctor was on his way to pick up the Ponds – there was a lovely new clothing garden on Phinkya 111 he thought they'd like – when he heard it.

Doctor.

Then stronger, again:

Doctor.

'Castiel.'

In a flash, he was off, powering the TARDIS as fast as he could through the Vortex, only one thought on his mind:

'Castiel. Castiel is calling for me. Castiel could be in danger. Castiel, Castiel, Castiel.'

It didn't take him long, and soon he felt the TARDIS settle down.

Flicking over the scanners with a concerned tilt to his brow, the Doctor studied what was happening outside.

What he saw made his face shut down in anger, and white hot rage cloud through his brain.

'Castiel.'

Immediately, he was at the doors, pushing them open and stepping through to glare at the demon who dared to hold Castiel hostage.

She – her 'meat suit' anyway – was young and pretty, with large dark eyes and dark hair, and skin just shy of 'too tanned'.

All this the Doctor noticed, but didn't notice either, because none of that mattered right now, not when a demon held his friend in a circle of Holy Fire, and for her sake she'd better not have touched him.

The demon seemed to have recovered enough of her wits to look frightened and speak as she backed away.

"Who-who are you?"

'Unimportant.'

"Did you lay a hand on him?" At any other time, the Doctor may have been shocked at the darkness running through his voice, the danger. But that didn't matter now. Castiel was the only thing that mattered now.

"Wha-what-"

"Did you touch him?"

He had to know!

"I-I was under orders. He was- He was not to be harmed." She flinched away, and he realised somewhere in his mind he had stepped forward, closer, just enough to seem threatening.

"Then you are lucky."

'Lucky I don't kill you now.'

"Who are you?" The demon whimpered.

The Doctor felt his lips tug up into a smirk.

"I'm the Doctor. Basically… Run."

That was all it took it seemed, as immediately the cowering demon straightened and black smoke poured from her vessels mouth, leaving the poor girl to collapse on the floor.

A tiny part of the Doctor's mind assessed her situation briefly.

'Dead.'

His uncaringness at that thought shook him slightly out of the furious fog shadowing his mind and he took a deep breath.

'Castiel.'

The Time Lord turned slowly to the Angel in question, still standing – slightly shocked – in the Holy Fire.

"Are you alright?" The Doctor asked. There was nothing else more important that needed to be said. If he wasn't…

"Yes." Castiel nodded, and swallowed almost imperceptibly. "However, the demon will tell others of this. Word will spread quickly through the ranks."

'Good.'

"Let it." The Doctor dismissed aloud. "Let all the demons of Hell know that you. Are. Protected." He looked down, shocked to see his feet had moved him forward on the last three words.

'Castiel. Holy Fire.'

Whipping out his sonic, the Doctor aimed it up at the sprinkler, sending water raining down upon them. The fire was extinguished quickly.

'If they had hurt him… I have to protect him.'

"Demons run." The Doctor looked up into unreadable blue eyes, confused.

"Demons run when a good man goes to war. That was the poem." Castiel elaborated.

The Time Lord looked down.

'What have I done? But they had Castiel…No. It was justified.'

A hand on his shoulder pulled the Doctor out of his thoughts and his green eyes caught the Angel's own.

And then the Doctor was pulling him into a hug, and it was extraordinary, because nobody's hugs could compare to Castiel's, not really, and the Doctor wanted to stay like this forever.

Castiel flew them and the TARDIS to a room of his then – a new experience the Doctor knew he would have thoroughly enjoyed under any other circumstances, and they sat and talked until the Doctor felt like he could breathe again, because Castiel was safe, with him, and that meant everything was okay.

They hugged again before the Time Lord had to leave, a soft hug, a warm hug, and the Doctor must make sure to get more of these, they were addictive, Castiel was addictive, and he really didn't want to leave.

But he had to, so he did. With a wave goodbye, the Doctor was off in his TARDIS. The Ponds were waiting for him, and at least for now, Castiel was safe.

The fourth time the Doctor visits, he's ready to brag of what his sexy – ahem, the TARDIS – can do, and he never thought he'd see the day. (Also known as the Doctor decides there is something a little more sexy than his TARDIS, and the old girl becomes matchmaker.)

The Doctor was thinking of Castiel. Again. The Angel hadn't, as of yet, seen inside his TARDIS. Now, that simply wouldn't do. His old girl was a thing of beauty, a thing of wonder, and it wasn't fair to keep Castiel from seeing such – alright, alright, he wanted to brag. Happy?

However, there was something else about his Angel that simply refused to leave his mind. And there he went again!

Possessiveness wasn't usually a trait of his, but the Doctor couldn't to stop calling Castiel 'his'.

It was a worrying thought, truly.

So the Doctor did what he was best at when he came to these things.

He ran away.

Well, not really ran away, because – completely without his permission – his traitorous hands set the destination for Castiel's current position, locking onto him a while after the last time he'd left (for his Angel, anyway. The Angel. Oh dear.)

The Doctor starts their latest adventure with a grin and 6 simple words.

"Want to see something truly amazing?"

Castiel smiles, and stands, and his expression when he comes into the console room for the first time is one the Doctor would give almost anything to see again.

Castiel's gravelly voice pulls him from his thoughts, and it's filled with wonder and awe and it makes the Doctor practically overflow with pride that he and his old girl put it there.

"Just how much bigger is the inside than the outside?"

The Doctor smirked. "You don't want to know. How big are your wings?"

Castiel copied the smirk perfectly, and the Doctor almost missed his next words because suddenly his knees were very, very weak. "You don't want to know."

'Oh, Rassilon. That is quite possibly the sexiest thing I've ever seen. Sorry sexy.'

He patted the console in comfort, but the TARDIS just hummed, amused.

'Amused? Why are you amused?'

"She is… Sentient." Castiel wondered, blue eyes wide as he continued with his slow sweep of the room.

The Doctor smiled. "Yeah. We've been through a lot together, this old girl and I." He touched the console again tenderly, making the TARDIS whir happily in response.

"Now!" The Time Lord spun to face his dark haired Angel again, and waggled his eyebrows. "What do you say we take her for a run? We'll be back in a flash, and I'll put her on random – she can pick anywhere in the Universe, anytime."

Castiel smiled at him, wider than the Doctor had ever seen him smile before.

'Wow…'

"That sounds great." The Angel was saying, and the alien grinned in return.

"Brilliant!" He ran around the console, setting the destination for random, clicking the de-fribrilator, pushing the autonomater, getting his old girl ready for flight.

"You might want to hold on." He advised Castiel with a smile.

Snapping the hand brake, the Doctor laughed in delight.

"GERONIMO!"

Immediately the TARDIS was off, jolting its way through the Vortex, throwing its two laughing occupants around the room, until finally, not long after, the ship gave one last heave – 'Was that on purpose, sexy?' – sending Castiel colliding into the Doctor as she landed, and went silent.

Panting and grinning, their position went unnoticed for a time, but all it took was one slight shift and it all became startlingly clear.

The Doctor was lying with his back against the cold metal floor of the TARDIS, and Castiel was directly above him – hands on either side of the alien's head, knees on either side of his legs, and lips – 'Oh, pink lips' – very, very close to the Doctor's own.

'Just a little closer…'

The Doctor could feel hot breath on his lips, and his eyes… His eyes were so blue!

And then there was a crash, and a jolt, and the TARDIS grumbled – 'grumbled?' – as the two were thrown away from each other.

Breathing in quickly, the Doctor leapt up, turning to see Castiel doing the same.

'Thoughts later. Right now… Wow-ing time.'

"Right! Ready to see what's out there?" The Doctor grinned in excitement. Castiel nodded with a smile, and the Time Lord ran down the ramp, placing one hand on the handle.

"Coming?" He asked.

Castiel followed him down, flashed him another smile, and then the Doctor opened the door.

Twin gasps rang out at the view, and rightly so.

'Sexy, have I ever told you you're amazing?'

The TARDIS was floating in deep space – if he thought on it more, the Doctor could probably recognise where, but this wasn't the time – and directly in front of them, surrounding a massive rock was a flame so white, so bright it seemed to put every other light to shame. A comet, just starting to burn.

"Beautiful…" The alien heard Castiel breathe out, and turned to him. The sight took his breath away.

Castiel's extraordinary blue eyes captured the light of the comet, reflecting and absorbing all at the same time. His face was bathed in it as well, making his pale skin seem to glow. He had never looked more like an Angel in that moment.

'Yeah...' He agreed to Castiel's thoughts earlier, but this time he wasn't looking at the comet.

Carefully, the Doctor settled himself down until he was sitting on the TARDIS' edge, tugging on the Angel's trench coat until he sat down too.

For a while they sat in beautiful, perfect silence, before Castiel looked up at the Doctor and smiled with a content sigh. "Thank you, Doctor."

The alien returned his smile, feeling calmer than he had in a while. "It's my pleasure." He replied.

Suddenly, the TARDIS tilted – 'What are you doing today, old girl?' – making Castiel lean automatically into the Doctor.

Shoulder to shoulder they sat in content silence, smiling softly and watching the comet pass by.

The next time Castiel is the one who 'drops in', feelings are exposed, the TARDIS is happy, and the Doctor experiences bliss (the good kind.)

The Doctor was fixing – well, "fixing" – underneath the TARDIS console when Castiel fluttered in. Not that he noticed. He was too busy thinking.

Of whom, you may ask?

Why, who else but his Castiel?

The Angel had wriggled his way into the Doctor's hearts, and though at first he was worried, now he wanted to take it further. But of course, he had doubts.

'He's an Angel. That changes the rules. Do Angels feel that sort of thing? Even if they do, how should I know if Castiel does? Oh, I'm acting like some silly 90 year old!'

Suddenly, the Doctor spotted the pair of shiny black shoes by his feet, and pulled himself out from under the console, standing to grin at his Angelic friend waiting for him.

Friends, was what they were. Both had some messed up pasts, both had made some pretty bad choices, but when it came down to it, they were different and the same, wrapped into a bundle of tan trench coat flashy bow tie.

"Hey, Castiel!" The Doctor greeted with a smile.

"I've been thinking, Doctor." Castiel's tone was grave, and the alien's smile fell immediately.

"What is it?" He asked, concerned.

'How can I help? I'll always help you. I don't even think I could say no to you.'

"There is something I have been meaning to do for a long time now, I think," Castiel continued, "I simply did not realise it until a mere day ago."

The Doctor frowned and furrowed his brow more in concern. "Castiel, what's wro-"

And then there were soft pink lips on his own, and blue eyes were closed, so the Doctor closed his own, and those lips were moving, and everything was just Castiel, and damn it if an Angel should be allowed to be such a good kisser.

Finally overcoming his surprise, the Doctor slowly lowered his own eyelids and leant into the kiss, lifting his hands to twine long fingers into Castiel's dark hair, pulling him closer, and all he could think was:

'Castiel, Castiel, Castiel.'

When they eventually pulled apart, they were breathless and both smiling widely.

"So…" The Doctor began. "This is…?" And Castiel nodded, and words failed both of them so they just kissed again.

The world shrunk to just them, just now, and in the background the TARDIS hummed and made a little sigh that sounded just a tiny bit like 'finally'. Because in her personal opinion, her pilot deserved this Angel, and this had been far too long in the coming really, and for a long time the Time Lord and his Angel stood in a sweet embrace.

EXTRA

When the Ponds find out, the Doctor is worried, and someone wants a wedding.

There was a large cockroach/squid/elephant thing coming at them, they were running for their lives, and the Doctor deemed this the perfect time to tell the Ponds of his new relationship status.

"Amy, Rory, could I have your attention please?" He yelled at them, dodging a bit of slime the monstrous creature threw in his direction. "I have something important to tell you!"

"Does it have to be now?" Amy called in reply, her accent as thick as ever.

The Doctor thought briefly on her question. Castiel had already told the Winchesters – or rather, the demon Crowley they were working with had revealed it, but still. It was only fair the alien did the same.

"Yes!" He finally replied.

"I really think it can wait Doctor!" Rory spoke up, ducking his own slime-ball.

"I am in a relationship!"

Amy stopped and stared at him. Rory, slowed to look. The monster behind them faltered in confusion. That was its downfall – literally. One long, trunk-like purple tentacle slipped, catching one huge foot and sending it tumbling to the ground, sliding until it stopped at the Doctor's feet.

"Wait, wait, wait, you're in a relationship?" Amy jumped over one tentacle as she made her way to him. "With who?"

"Not going to try and get away from it while it's down then?" Rory asked, glancing at the creature in worry.

"Hush Rory." Amy's eyes were fixed on the Doctor, and he grinned.

"With an Angel of the Lord!"

"Wait, what?" Rory turned to him. "You're in a relationship… With an Angel?"

"Oh!" Amy's brow cleared in realisation. "That celestial disturbance or whatever that you told us about! So what's his name?" She leaned forward eagerly.

"Castiel." The Doctor replied with a grin.

"Is he cute? Can we meet him?"

The Time Lord blushed slightly and fidgeted.

"Well, yeah, he is, I guess. I want you to meet him!"

Amy's smile was widening and a glint appeared in her eyes.

"So… How far have you gotten?"

"Amy!"

"Hush Rory."

"How… Far? What do you mean how far? How far where?" The Doctor's brow furrowed in confusion and Rory groaned.

Amy rolled her eyes. "Have you kissed?"

The Doctor blushed again. "Yes."

"Have you used your hands, you know, 'down there'?" The alien flushed immediately as he understood what she was getting at.

"Amy!" He and Rory exclaimed at the same time.

"Ooh! Is there going to be a wedding? Can I come? Can I design it?"

Spluttering, the Doctor stalked off, leaving Rory to deal with the whirlwind of plans that was his wife.

The Doctor muttered to himself under his breath and changed direction for the TARDIS. They still had to catch the crazy woman behind this.

He sighed.

"Ponds."

Everything does work out eventually. The Ponds are more than happy for the Doctor, though they – meaning Amy – insist on meeting Castiel. The alien even says he can meet Craig, one day.

The Doctor gets to properly meet the Winchesters and Crowley (who promptly tries to get him to drink scotch and perhaps drunk).

So time went on, as it always did, and the Doctor and Castiel were happy. No doubt there were problems, of course. The Apocalypse still had to be dealt with, and there was the whole mess with River that the Doctor really had to get sorted out, but every relationship has problems, doesn't it?

They weren't perfect, but they were beautiful.

And if the TARDIS had any hand in the two finding love? Well, the old girl would never tell.

THE END
