Supernatural.
After a familer flap of wings were heard, a younger version of the trench coated angel appeared. "How do I know this isn't a demon?" John asks looking over the angel. "Because this sure as hell doesn't look like an angel."
"I can assure you that I am indeed an angel of the lord." Cas says still confused on why the hell he was here. "Where's your halo and wings, then?" John asks raising an eyebrow. Cas sighs, then with the flash of light, his wings appeared in his shadow with his eyes glowing bright blue.
Young Sam and Dean were looking very confused, a little afraid, and a lot amazed. "Okay, so angels are real." John says nodding slightly. "And you told this one to 'get your feathery ass down here?'" John asks a little scared.
"Don't worry, I do that a lot-" Dean starts but is cut off by Cas. "You are not from this time, nor have I ever gotten a prayer like that." Cas says squinting and tilting his head a little at Dean. "Yeah, we're trying to get back to our time, 2015." Dean says.
"Yes, the spell you cast is unreverseable, it can only become undone with time." Cas says, then looks slightly confused. "But how could you cast the back in time spell not knowing it wasn't a spell to find an angels grace?"
"Can you not do the mind reading thing? It kinda freaks me out and I get a headache after." Dean says to the angel. Cas nods then looks around. "You brought the key from the future." Cas says tilting his head.
"Yeah. We got lazy." Sam says. "So we just have to wait until the spell wears out?" Sam asks the younger trench coat angel. "Yes, I believe so." Cas says nodding.
"So our future selves are stuck in our own time? This is kind of confusing..." Young Sam says still totally confused at the situation. "Yeah, basically. That is confusing." Young Dean says. There was another flap of wings and there was no trench coated angel, of course.
"... Does this happen all the time?" John asks after realizing Cas zapped out. "Yeah, he zaps out a lot." Sam says crossing his arms. "How did you boys even get caught up with angels?" John asks sighing.
"Uh... Well... Its a long story." Dean says shifting a little. "We have the time." John says taking a seat at the table. "So basically... Uh... We get into a car accident and I almost die, but you sell your soul and the colt to save me." Dean starts.
"Whats the colt?" John asks, cutting in. "Its the only thing that could kill the demon at the time." Sam says. "Then you die and then I get kidnapped and stabbed and Dean sells his soul to get me back." Sam says.
"Then I die and Cas pulls me from hell, then we start the apoculasp-" Dean starts but gets cut off by his father. "You boys start the apculasp? Wow." John says not sure whether to be impressed or angry.
"Yeah. Then Lucifer comes out of the cage and we shove him back in, along with Sam, then he comes back soulless. Then we get his soul back and Cas becomes God after eating all the souls from purgatory." Dean says.
John blinks in surprise but lets Dean continue. "Then Cas puts the souls back and unleashes the leviathans. Then Sam starts seeing Lucifer and we run into a prophet of the lord. Then I kill the leader of the leviathans and go to purgatory. Sam gives up looking for me and I come back, we have a fight. Then we have the chance to close the gates of hell forever but it would cost Sams life so we don't take it." Dean says. "But Sam gets hospitalized and the only way to save him was to have an angel possess him."
"So Dean lets an angel called 'Ezekiel' into me. And the angel was actually Gadreel. So Ezekiel was Gadreel pretending to be Ezekiel pretending to be me." Sam says. "And then I-Gadreel- kill the prophet of the Lord, Cas looses his grace and here we are."
"... Wow. My boys have been through a lot." John says not sure what to say. "Yeah. Its been crazy." Dean says."Yeah, I can tell." John says rubbing his face. "I need a beer." He says. "You'll need something stronger if you have to deal with angels now." Dean says sighing. "They are giant dicks."
"... Don't you hang out with one, though?" John asks looking up to Dean. "Well, Cas is an exception." Sam shrugs. "He's still a dick sometimes, even then." Sam says. Dean reaches into his pocket and takes out the impala keys. "I think you'll need these." Dean says tossing it to his father.
"If you have the key to whatever this is, don't you have the keys to the car?" John asks catching the keys Dean threw to him. "Yeah, but its a different engine. I had to rebuild her a ton of times." Dean says.
"Oh. Good to know you took care of her." John says then stands. "I'm going to get some beer. I'll be back in a bit." John says then leaves the bunker. So now it was an awkward silence between Sam, Dean, Sam, and Dean.
"So, uh, the future is pretty messed up it sounds." Young Sam says trying to start up conversation. "It is. Without us there wouldn't be a world." Sam says leaning against a wall. "So we save the frigging world?" Young Dean asks a little suprised."Yeah, kind of." Dean says answering his question. So they just talk for a while. "Do you think Dad's taking a little long?" Young Sam asks checking his watch. "Its been a few hours since he left."
"Yeah, but he probily just-" Dean starts but gets cut off by Young Dean's phone going off. Young Dean answers it and goes pale at what the person on the other side said.
