"SAM!"

Sam suddenly woke up from his bed, alert and winced slightly at the uncomfortable feeling that he felt. As he looked around, the feeling grew in the pit of his stomach and he felt as if he was looking at his room from somebody else's eyes.

He jumped off his bed and was a little confused at the fact that the bed seemed a little bigger than he remembered. But he had more important things to take care of.

"Dean!"

Sam crept out into the corridor and got ready to strike as he opened Dean's door. He waited with anticipation as the door slowly opened to reveal….himself!

"Well, this is weird," Sam commented, scratching his head a little confused.

"No dude, you're not staring into a mirror," his reflection said to him, "It's me….Dean!"

"Wha…but…how?!" Sam stopped talking as he saw his own reflection in the mirror-an actual mirror this time. He stared stunned at who he saw in the mirror.

'No, this can't be happening,' he thought, 'Not right now. Not to me.'

He raised one arm, then the other and then he waved them around.

"Dude, stop flailing your arms around like a monkey!" Reflection Sam-or Dean-said to him, looking a little annoyed, "You're making me look bad!"

"Dean," Sam called out to him, as he sank onto Dean's bed with his head in his hands, "Am I you?"

Even before Sam asked that question, he knew that what he was going to say wouldn't make sense but his brother would understand exactly what he meant.

"I dunno Sam," Dean sighed as he put his arms up questioningly. He was at a complete loss of what to do, "How is it fair that you get to be the handsomer brother this time?"

Sam just rolled his eyes and shook his head, or technically Dean's head, since he was in Dean's body.

"So is this like Freaky Friday?" Sam asked suddenly horrified. He wondered what he'd have to do to get back into his own body. Thankfully they didn't get a lot of guests here at the bunker, so explaining the situation wouldn't be a big problem.

Also they'd been in weirder situations than this, so none of the people who visited would be freaked out or anything. But Sam felt really uncomfortable to move around in his brother's body, sort of vulnerable. Plus now that he was actually shorter than his brother, he had to look up at Dean rather than look down at him like he used to.

"Yeah seems like it," Dean shrugged, "Except I don't get swapped into the body of a hot, young teenager. I'm just stuck with your gigantor ass."

"Yeah, and I'm stuck with…," Sam tried to think of a better retort, "this!" Sam pointed to himself-in Dean's body.

"Yeah well at least I eat plenty and I'm not gassy like you!" Dean accused, the sides of his mouth curling up into a smirk.

"And at least I have a shower every day and don't smell like…," Sam tried to smell himself-or Dean's body-and almost threw up, "….shit!"

Just as Dean opened his mouth to give Sam a snappy reply…

They both heard the doorbell ring.

"Oh crap," Sam mumbled, his worst thoughts having turned real. Whoever this visitor was couldn't have come at a worse time but if he/she was here then it must be pretty urgent.

Sam and Dean went over to open the door, and standing right in front of the door, was Castiel.

"Hello Dean. Hello Sam," Castiel gave them both a curt nod.

"Hey Cas," Sam and Dean said together and then narrowed their eyes at each other.

Castiel, having been with the boys for a long time now, didn't even blink at it. He knew that the boys liked to pretend like it had never happened, even though it happened pretty often.

"Why are you here?" Sam-who was in Dean's body-asked him, "Is everything alright?"

Castiel looked a little embarrassed as he said, "Yes and no."

"What do you mean?" Dean-who was in Sam's body-asked him.

"I mean this," he said angrily as he pulled up his sleeves to reveal a tattoo on his arm. As both the boys took a close look at it, they saw the trickster's familiar face gazing up at them and below that it said 'Cas loves Gabriel'.

"Whoa, Cas," Dean said, "I never knew that you swung that way." Castiel gave him a face that said that he would punch Dean in the face anytime now-Sam's face-which was exactly what Dean wanted. Sam deserved a punch to his face.

"Hey Sam," Sam said to Dean, giving his brother his famous bitch face, "Why don't you just shut your mouth!" And as much as Sam felt like Dean deserved that punch to his face, it would be Sam's handsome face that would get damaged in the process and that was a risk that Sam wasn't willing to take.

"Hey Dean, stop being such a jerk to me man," Dean gave Sam a smirk in return. Since he was 'Sam' now, he figured that he would have to call 'Dean' a jerk.

"I'm always a jerk, bitch," Sam smiled at the statement, "you should know that by now." Sam's smile widened with the knowledge that he was clearly playing Dean's part too well. And it felt sort of satisfying to say the 'b'-word to his brother, even though he was indirectly just saying it to himself.

Castiel glared at both angry and confused but got straight to the point as he said, "I think that my brother Gabriel might still be alive."
