Because the TARDIS was parked in the middle of your living room, the Doctor didn't do any actual flying. He just teleported from your dorm to outside Crowley's hideout in Scotland.
Amy was the first out, "Ah, Scotland. It's good to be back. Now, where are we off to?"
"According to this, just a few feet in front of us." As everyone stepped out after Amy, they looked around, confused, because there was nothing that screamed 'Evil lair right here!' There wasn't any buildings, shacks, ruins, caves or openings in the hills.
"Uh, yeah, I don't know if its obvious or anything, but thERE ISN'T ANYTHING!" Dean looked ready to blow someone's head off, when the Doctor took a step forward and vanished.
"OH SHit!" Dean and Sam jumped back, Amy screamed, "DOCTOR!" and ran towards were he'd vanished.
"No, Amy!" You reached out to grab her, but she was too fast, darting past you and vanishing. "Ah, shit." you ran after her and when you reached the point were they had vanished, the air shimmered for a moment and a tall castle appeared in front of you, as well as the Doctor and Amy. You heard screaming and saw Dean and Sam running towards the shimmer. The moment they passed through, a laughter rang through the air. Sam and Dean raised their guns and dropped into their fight stance. Where the fuck had they gotten guns from? Did they pull it outta their asses?
"Crowley! Show your stupid ass face!" Dean yelled towards the building.
"Well, well, well. It looks like you brought some company, boys. Can't take me on by yourselves, can you?"
"Well why don't you come out and we can test that."
With a burst of smoke, Crowley appeared at the foot of the castle entrance. Dean and Sam rushed for him, but Crowley moved and they stumbled, almost falling. The Doctor had pulled out his screwdriver and looked like he was trying to shut down the 'device' allowing Crowley to teleport. Dean and Sam kept trying to rush him, trying different strategies, like Dean being bait, while Sam snuck up on Crowley. None of them worked, Crowley just kept teleporting at the last second, often resulting in the brothers crashing into each other.
"Why can't I stop him?" the Doctor was banging his screwdriver against his hand and kept pointing it at Crowley.
You stepped closer to the Doctor and said, "That's because he isn't using any electronics to teleport. It's something he can do naturally. Instead of jamming electronic signals, try dampening any bio energy he's giving off."
He nodded and tried it, just as Dean and Sam were lining up to rush Crowley from the front and back. Crowley had a smug look on his face, but as the boys drew closer, it quickly grew to a look of panic as he wasn't being teleported. The boys reached him just before he could react, tackling him to the ground.
"Now listen here, you son of a bitch, you are going to send me and my brother back to our world or so help me, I will blow your head off!"
"Now, now, Dean, I won't be much good to you dead, will I?"
"Oh, quite whining. You won't die, you just won't be able to have your old body back."
Crowley look horrified at that, and relented.
"Alright, fine. I'll zap all your bloody arses back. Just don't touch the face."
Crowley started casting the spell, but you clamped a hand over his mouth before he could say anything else. Everyone looked at you funny, Dean once again ready to rip your head off.
"Look, we are in Scotland right now. I live in New York. I don't have anything with me that will let me get back home by myself. Once you get me back to my college, Crowley can finish his spell, but not before."
Dean muttered and grumbled, but agreed, as did everyone else. Once everyone was in the TARDIS and Crowley restrained, the Doctor zipped back to your college and dropped you off. You waved goodbye to everyone as they vanished in a flash of bright light.
"No one's going to believe me." you thought as you walked off, back to your dorm, "Ah, well. Whatever."
