A/N: This was written for the "Delight In Dean Comment Fic Meme" on spngenlove, in response to the prompt: "Going happily along with Dean's fear of flying: the boys find themselves investigating a haunted roller coaster. Bonus points for Dean freaking out while stuck in the front car as it slooooooooowly climbs the first giant hill." Thanks to Wave Obscura for beta'ing.

"You gotta relax," Sam says for what must be the hundredth time.

"I know," Dean growls through clenched teeth.

"It's gonna be okay," Sam says, and he uses this fucking soothing voice, like he's talking to some spooked mouse.

"Would you please shut the fuck up? I'm trying to... concentrate."

Actually, he's wondering whether he can jump from the train before it leaves. This ghost hasn't hurt anyone, right? They just need to take a good look at him so they can identify him, and stop him from scaring roller coaster riders with his howls. And Sam can do that perfectly on his own.

But too late, because they're already moving. Dean closes his eyes, then opens them again because feeling the train move without being able to see anything just makes him nauseous.

He just has to find something he can focus on, something that will make him forget where he is. He also has to avoid looking down... and of course, that's what he does. Jesus Christ people look so tiny down there that he has to refrain from screaming.

He swallows. His heart is in his throat, or feels like it. Is he going to throw up? Oh god, please no. Sam would never let him hear the end of it. He tries to think about music, because music always calms him down, but the only music he can hear in his head is annoying and whiny. It takes a minute for him to identify it.

"Why am I thinking about the music in Vertigo?"

He catches Sam's smirk.

"Is this funny to you?"

"No, Dean, it's just, it's kinda appropriate, don't you think?"

Dean breathes in deeply and decides to ignore his brother. Okay, he can do it. If only the train wasn't so fucking slow.

It feels like they've been on it for days, now. Long, slow, agonizing days.

"Remind me why we have to ride on the front car, again?" he asks Sam, forgetting his decision to ignore his brother.

"We'll be able to see the ghost better that way. He's gonna appear in front of us on the track when we get to the top of the first hill."

"Any hope of getting there before the end of the week?"

"Come on, Dean, it'll be over soon."

"I hate you."

"I know, Dean."

Dean tries to look at the sky, as it is the only not moving thing right now, but it proves to be a baaaad idea, because the sky is so fucking huge, empty, endless, and... He closes his eyes, feeling so dizzy his head hurts.

"Dean, you okay?"

He feels the comforting weight of his brother's hand on his shoulder.

"Ye... yeah."

He would raise a hand to reassure his brother, if his hands weren't gripping the lapbar so tightly.

"Are we there yet?" he squeaks.

"Almost." Then, seconds or minutes later. "Dean, we're reaching the top."

Dean forces his eyes to open. He looks at the track in front of their car, and does not make the mistake of looking down again. He doesn't see any ghosts, though.

"Sam, where..."

"Oh. Fuck."

"What? What? No, Sam, you don't get to say "oh" like that when we're at the top of a fucking..."

"Uh, Dean. I... I'm sorry, I think... I think we got the wrong roller coaster?"

"The wrong... You better not be saying what I think you're saying!"

"What I'm saying is... We're not on the right roller coaster. There... there's no ghost on this one."

"You mean we're gonna have to do that again, is that what you mean?"

"Yes? I'm sorry, I don't... Ow."

Dean has to admit that his fist feels pretty damn good on his brother's mouth. And for one whole minute, he's not even scared anymore.
