Sam phones Bobby, Dean packs up shop.

"He says he'll try, but he doesn't know if there's anything on people just... popping out of Hell," Sam says, huffing disappointedly. "But he did find a hunter to take the case."

"I don't believe it..." Dean says, dropping his flashlight in his hasty frustration. He cursed and picked it back up. The room was still dark. "Of all the friggin' ghosts..."

"Well, I mean, it's better than him being tortured in Hell, Dean...!"

"I don't trust it, Sam!" Dean shouted, hitting his shin on a table he knew was against the wall a second ago. Adam was just fucking with them now... "He was in Hell! He can't just be BACK!"

"Stranger things have happened!"

"No, Sammy, they haven't!"

The younger Winchester was stumped. Dean had a point this time.

They packed up in total darkness and almost total silence. Their half-brother must be getting a kick out of watching them trip over whatever furniture he moved in the dark. The miniature motel room suddenly became a maze of bruised shins and anguished screaming. Eventually, the two managed to file out into the impala and get on the road. They weren't even down the block yet before the radio flickered to life.

"No, no, no, no, no, no, NO," Dean said, as some saccharine bubblegum pop song blasted through the speakers.

Sam turned off the radio, hoping against hope Adam would keep it off this time.

Of course not. This time, some alternative rock wannabes with unintelligible lyrics. Dean and Sam collided heads in an effort to turn it off as quickly as possible. While they were cursing and rubbing their heads, Avril Lavigne made an appearance on Adam's "Hits From The Pit" playlist.

You say that I'm messing with your head, yeah yeah, yeah, yeah...

"You've got some shitty taste in music, Milligan!" Dean growled, turning back to the road. While Sam fiddled with the radio, trying to make it stop. He kept shooting dirty looks at the backseat.

"I remember him being a bit-"

"Less of a bitch!?"

Adam turned it up.

All my life I've been good, but now,

I'm thinking, what the hell?

All I want is to mess around!

And I don't really about,

If you love me,

If you hate me,

You can't save me, baby, baby...

"Why is he following us?!" Dean shrieked, pounding his fist on the steering wheel as the radio changed again. It was by Ellie Goulding, but neither brother knew the name of the artist. They didn't even know the song.

And so I tell myself that I'll be strong

And dreaming when they're gone

'Cause they're calling, calling, calling me home

Calling, calling, calling home

He could trip them until they bled, but if he thought he was going to blow out Baby's speakers without some kind of punishment, he was very, very wrong.

"We are not your goddamn home, Adam!"

"We're the only family he has left, Dean..." Sam desperately tried to calm his brother, despite his own temper rising.

"Then why is he doing..." Dean angrily searched for words. "T-this?!"

The radio changed again, this time to... Taylor Swift? Disgusting. Dean was beginning to question if Adam was really related to their father.

And I know you wouldn't have told nobody if I died, DIED, for you...

Died for you...

Sam pulled out his cellphone. No texts from Adam, no strange backgrounds. Well, while it was out he might as well try it...

He opened the phone's camera and pointed it around the impala.

Just as he thought.

Adam was sitting in the backseat, the stupidest grin on his bratty little face. At the sight of Sam's camera, he clicked his tongue and winked, pointing two "pistols" at his half-brother.

"Oh, that's very cute, Adam," Sam growled. His family had some experience with Hell changing a person, but he'd never seen it take a pre-med student and turn it into a snot-nosed kid in dire need of a spanking.

"What is it?" Dean asked, glaring at the road ahead.

"He's in the backseat..." Sam said, watching Adam make a variety of silly faces and obscene gestures at him. "Yeah, that's real mature..."

"What's he doing?"

Sam turned off the camera. "Being a brat."

"Great... Just great..." Dean muttered. "We're roadtripping with the eight-year-old from the great beyond..."

Adam responded with a new song.

I'll weigh you down, I'll watch you choke...

The Winchesters exchanged glances. This was going to be an awfully long trip.

"Well, look on brightsi-" Sam was cut off by a small thud.

Dean chuckled, despite the situation. "Did he just...?"

"Kick... my..." Sam said slowly. "...Chair..."

Dean tried to laugh at his brother's misery, but he was quickly shut up. Adam was having way too much fun.

"Aren't you nineteen?"

The radio was turned up yet again.

Say it ain't so, I will not go,
Turn the lights off, carry me home...
