"The Blue Light"
Superwho;Castiel meets the Doctor.
(Spoilers for Supernatural 7x01)
Castiel sees the world through a thick haze, barely able to make out the faces of his friends who stand before him. “Go!” He’s screaming at Bobby and Dean, but they don’t move, not an inch, and their faces don’t change from their terrified expressions. The just watch as Castiel begins to convulse, his head and neck snapping every which way as the Leviathan tries to take control of Castiel’s vessel. Castiel’s vision blurs black around the edges and he crouches to the floor, hoping to focus on something and be pulled by his mind from the depths he’s sinking into in his vessel, to no avail. Staring at the stone floor and concentrating on the specks of dirt and discoloration, he thinks, might, just maybe help him draw his mind back to the world, so he stares, focuses on a single tile and then a single speck, though the black edges are closing in on his vision even as he struggles with all his might to hold them back.
He hears a voice then, but maybe he’s heard it all along. All he knows is that it’s only now reaching his eardrums, and even with how muted and blurred the voice sounds, Castiel can tell it’s a man screaming at him with all the power of his lungs and an obvious English accent, “Hey! Get in the box!”
Castiel looks up, barely holding onto the control of his body by a thread, and if any part of his mind was free to think, he’s be astounded by the blurry sight of the blue box that most certainly had not been in the room all along. He doesn’t think about it, though, he doesn’t have time to care, and the man is still yelling and he has nothing to lose, so he uses all his strength to climb through the box’s door.
He stumbles and trips the few steps it takes, before climbing into the box, still staring at the ground because lifting his head would be much too strenuous and every inch of him already aches horribly. Soon, the only vision he has is a small blurred dot in the center. It takes all his strength to croak out a weak “What-“
Castiel sees blue- an electric blue glow that, even as he tries to look around, doesn’t diminish in the least. There’s something pulling at him from every direction and Castiel feels like it’s trying to tear his insides out. It only pulls harder as the light gets stronger, and Castiel’s eyes ache but even as he closes them the vibrant blue doesn’t falter. And suddenly, the light is gone and Castiel falls to the floor in a crumpled heap.
He’s exhausted, something he’s never once felt in his time on Earth, and when his mind properly comes to, he realizes that it’s his mind only, that the Leviathan is gone. He can rest, and so he does, letting his eyes slip closed without a single thought of what may be happening around him.
Suddenly, Castiel hears the man again, and he can tell that the man’s face is quite close to his. His brow furrows for a moment, because didn’t Dean say that people valued personal space? “Well,” the man says, and Castiel’s eyes blink open and he turns his head, now face to face with the stranger.
“Hello,” Castiel says, and the man jumps up to his feet.
“You’re up! Excellent!” The man’s hair is askew and he wears a bow tie, an odd little accessory that Castiel doesn’t see many of, though decides he likes.
“Who are you?” Castiel asks weakly, coughing as the words leave his throat. He props himself up on his elbows and looks around- in no way is he still in that blue box. He seems to have been transported to a console room of sorts. He blinks, confused, as he’s sure he would have noticed being transported, and it feels nothing at all like the strange episode with the blue light.
“I’m The Doctor,” replies the man, a smug, proud look on his face.
“Doctor,” Castiel repeats, perplexed. “Do I need a doctor? Do I have any open wounds?” He searches his body frantically for any blood or breaks that he hasn’t healed, though finds none.
“I’m not a doctor,” the man says, a glimmer in his murky green eyes. “I’m the Doctor.”
Castiel decides to leave matters alone on that, instead prompting for a much more obvious question: “Did you kill the Leviathan?”
“Sure did,” said the man- the Doctor- matter-of-factly as he tapped the air with some sort of metal stick.
“How?” Castiel asks, utterly bewildered and intrigued.
The Doctor tossed the stick up into the air, watched it flip, and caught it again with the slender, nimble fingers of the same hand. “With this. A sonic screwdriver, Angel.”
Castiel blinks. “What?” He forgets to ask about the sonic screwdriver.
“Angel? Angel of the Lord? Prefer a different term?”
“I… no… I…” Castiel sits up and scratches his head, absolutely baffled. “How do you know that?”
“I can see your wings,” says the Doctor, a mile wide grin plastered on his face. “Quite beautiful wings they are by the way.”
“But that’s impossible,” Castiel says blankly, eyeing the Doctor with wonder. “No human can see my wings.”
“Oh, but I’m not human. Thought you’d have figured.” The Doctor smirks.
Castiel knows the Doctor isn’t an angel, but what else could he be? “You’re not a demon,” Castiel muses aloud.
“Well I certainly hope not,” the Doctor says, chuckling. “I’m a Time Lord.”
Castiel raises an eyebrow and tilting his head. “What’s a Time Lord?”
“I’m an alien. From outer space,” he said, waving the sonic screwdriver in the air, Castiel guesses, to symbolize outer space. “The planet Gallifrey, more particularly.”
“Aliens aren’t real,” Castiel mumbles as he continues to look around the room, trying to process what he’d just heard. “Are they?”
And the Doctor only chuckles again. “Oh, Angel, it really is a shame how you know so very much of your world and so very little of the others. Yes, they are real. Very real.”
“Oh,” Castiel mouths, and he’s still so confused. He figures he should gain information while he still can, so he asks, “What does your screwdriver do?”
“Lots of things. Kills Leviathans. Lots and lots of other things too,” chatters the Doctor. “In fact, if I tried to make a list of all those things, it probably would never stop. Now tell me, Angel, have you got a name?”
“Castiel.”
“Hello Castiel, very nice to meet you,” the Doctor says, the greeting very long overdue, and leans down to shake Castiel’s hand and then help him up off the floor.
“It’s nice to meet you too...” Castiel says awkwardly. “…Doctor?”
And the Doctor grins again. “Castiel, it may be a bit soon to propose this, but seeing as I just saved your life, you wouldn’t by any chance be interested in traveling the universes with a lonely old man, would you?”
But he isn’t old, Castiel thinks, not at all. Though, he decides to leave that matter alone as well. “I need to go back to my friends.”
The Doctor’s face falls and Castiel feels sorry at once. “Alright.”
“I’ll find you if I change my mind,” Castiel offers as an afterthought, and the Doctor’s moss eyes light up like a flashlight as his joyful expression returns.
“Will you really?”
Castiel decides, since the Doctor seems to know very well what he’s talking about, when the Earth is at peace and the Winchesters no longer need him, he will.
