I eventually got up from my seat in the diner and took a bathroom break.  As I washed my hands in the bathroom, I made eye contact with my reflection in the mirror.

Behind me, I saw a flyer for the Enchantment Under the Sea Dance.

So, this is cinematic 1955.

I dried my hands, then headed out of the bathroom.  When I came out, I was in a hallway of what appeared to be a high school.  I followed it into a library.

"...Say it one more time but just a little bit more Arnold," said a voice.  "Ya know, like 'It's not a Tulpa.'"  The man mimicked Arnold Schwarzenegger's voice.  And that man was Dean Winchester, almost seven years older than when I'd last seen him.  He was speaking to Sam, and two young girls were with them.

I heard Arnold's voice not too long ago.  Much more intimidating. 

"Dude, come on."

"Hey!" I said, trying to get their attention.  They continued to talk. "Hey!"  I waved my arms.  No reply.

"...the goddess of epic poetry--the muse."

I bit my lip in frustration.  "Sam? Dean?"

"...So...the scarecrow is still alive, and we burned my prop for nothing?" one girl, Marie, said.

"Oh, that thing needed to burn," Dean told her.

My frustration doubled.  If anyone could help me, in all of these fictional worlds, it was Sam and Dean.  After all, it was Dean's amulet that had the mojo.  And it's connected to angels, so maybe we could find Cas...

I placed my hand on Sam's shoulder.  He didn't react.

"...Then she eats the author."

"Okay, that's bad." Marie had a look of fear in her eyes.  I didn't blame her, although, she was going to be okay.  Which I would tell her if someone would pay attention to me.

I screamed in more frustration, shaking Sam.  Although, Sam didn't exactly move as I yanked his shoulder.  The same happened with Dean, and the girls.  I could touch them, but I couldn't change what they were doing.

Why?  It's not like characters haven't noticed me so far. I ordered food in Broward County, Florida.  I spoke to Goldie when I chose not to order food in Hill Valley, California.

I looked down at bump under my shirt, the amulet around my neck.

"Bastard," I said.  I reached to remove it, but it wouldn't come off.  I gasped, seeing the skin on my neck.

Black swirls, resembling tattoo ink, had formed on my skin around the amulet and the string.  I scratched at it with my fingers, but it wouldn't come off.

It felt...permanent.

What if I could not prevent it, and I was to go from one fictional world to the next until I died?

My heart raced.  I began to hyperventilate.  This was a life dream, a wish that everyone has made at some point in their life, gone wrong.

My perfect dream was rapidly turning into a nightmare.

I followed Sam and Dean around for awhile, constantly trying to get their attention, but I concluded that I was invisible somehow.  When I went to the bathroom and stared into the mirror, this time I saw nothing; there was no reflection of myself.

Sam and Dean had been running around all night chasing Calliope, and now she was dead.  I stood beside them, to their right, watching the play.

"Out on the road...just the two of us."

"The two of us against the world."

"What she said," Sam told Dean.

The cast stood in a line facing the audience, and the piano began to play.

"Carry on, my wayward son," they sang.  I smiled.  Supernatural had made it one of my favorite songs. "There'll be peace when you are done."  I began to sing along, since no one could hear me, anyway.  "Lay your weary head to rest / Don't you cry no more / Once I rose above the noise and confusion / Just to get a glimpse beyond this illusion / I was soaring ever higher..."

"Who's that?" My singing was interrupted by a question to my left.

"Oh, that's Adam, John Winchester's other kid."  I looked at one of the girls standing and singing.  "He's still trapped in a cage in Hell with Lucifer."  I watched their singing with a frown, feeling awful for Adam.  Boy, I'm sure he's pissed.

I eventually rejoined the song, closing my eyes and allowing myself to fade out of reality, or ficitionality (that's not a word, but I'm going to pretend it is), that is, for a moment.

"...And if I claim to be a wise man / It surely means I don't know / Carry on, my wayward son / There'll be peace when you are done / Lay your weary head to rest / Don't you cry no more."

The singers created a beautiful harmony, "Carry on..."

There was an applause.  I clapped, too.

I followed Sam and Dean to the Impala.  As they climbed in, I reached for the back door, pulling the handle.  It wouldn't budge.

Of course not.

Dean started the engine.

No!  I had to go with them!

The car began to drive away, and I was shouting.  Suddenly, I was in the backseat.  I was confused, yet relieved.

-

Sam and Dean drove for an hour, stopping at a hotel not far from Detroit.  They climbed out of the car and went inside.  I tried the door again, but it still wouldn't budge.  I closed my eyes and pictured myself outside of the car, hoping I would teleport, or whatever had happened back there.

Nothing.  I was still in the backseat.

I groaned.

Still, though.  This was a pretty cool car.  It was the Impala.  The Impala. Baby.

Well, looks like I'm not going to get out of here any time soon.  So, what next? Maybe Cas would know what was going on.  But where was he?  I closed my eyes again, thinking hard. Hannah.  He was with Hannah searching for angels.

I kept my eyes closed, deciding to try something.

"Cas," I prayed.  "I don't know if you're getting this, with your borrowed grace and everything, plus whatever weirdness I'm going through, but I hope you do.  And this is for Hannah, too, so surely this message is getting to you somehow.  Look, I...I...uh.  I know where your grace is...roughly.  Maybe...maybe I can help you find it.  But, I need help, too.  I have Dean's amulet, and it has some kind of angelic power...You're the only one that I think can help, or would be willing to, anyway.

"But, yeah.  I need help.  Um, I'm trapped in the Impala?  And I don't have those carvings on my ribcage, so angels can still track me, right?  I understand that you'll probably have to drive here, too, since you lost your wings, but, I hope you come.  Because I need you, no matter how long it takes to get here.  And no one else seems to be able to see me or hear me.  Heck, I don't even know if you can.  Just, please.  Please help me.  You don't even know who I am.  But, uh, the reason why I know who you are and all, well, it's a long story, and it's all because of this amulet.  So, yeah.  Please."

I opened my eyes awkwardly.  Maybe that worked.

I drifted off to sleep after about fifteen minutes.  I didn't wake until I felt the car shake and the doors slam closed.  Light streamed on my face.  I squinted from the sudden brightness.

"Dude, I can get breakfast," Sam said.

"Every time I send you, you always forget the pie, so, no, I'm coming with you," Dean said.  Sam sighed with a smirk on his face, shaking his head.

"Okay, fine."

"Besides, you can pick up your rabbit food yourself."

Instead of getting breakfast groceries at the gas 'n sip, they climbed out and decided to eat at a neighboring restaurant.  My stomach growled, but, once again, I was trapped in the car.

I growled in frustration.

This was happening again when they got out for lunch as they headed south, and they were heading that direction for no apparent reason.  At least one I didn't know.

All that I could do as my stomach constantly begged for food, and my bladder pleaded with me to relieve it, was listen to their conversations.  This is what happened before they went for lunch:

"So what are we eating this time?" Sam asked.  As Sam asked this question, Dean applied the brakes and turned right into a parking lot.  He stopped the car.  "Hooters?"

Dean grinned.  "Hell yes."

This time, when they opened the doors, I tumbled over the seat into Sam's lap and rolled out onto the asphalt.

It was a bumpy ride to get there, but it was so nice to be free again!

When they opened the restaurant door, I made sure I slipped inside before it swung back shut.

A waitress walked by.  Dean grinned again, his eyes going up and down her body.  She smiled back at him as she passed, and once her back was to him, Dean stared at her butt until Sam nudged him.

Dean closed his mouth, nodding and biting his lower lip.  "Right, we should sit down now."

I searched for a restroom sign.

Once Sam and Dean were seated, Dean continued to check out all of the waitresses.  "Dude, this place is awesome.  We should come here more often."

Sam stuck his chin out, rolling his eyes.  "Okay..."  He picked up his menu.

I finally found the sign, and then I began sprinting to the bathrooms.  And, well, let's just say I definitely relieved myself.  I flushed the toilet, which was full of my luscious yellows, then washed my hands.  I still could not see myself in a mirror.

When I was finished, I found Sam and Dean and sat at their table without their knowledge.  My stomach screamed for food.  Eventually, Sam and Dean received their orders, steaming hot and looking delicious. I reached for a fry off of Dean's plate, then placed it in my mouth.

I practically screamed in pleasure as I finally had food.

I took a lot of Dean's fries.

"Dude, stop taking my fries, would you?" Dean said to Sam.

"What?" Sam said.  "I'm not taking your fries."

Dean motioned to his plate, which only had a few left.  "Well, then where else did they go?"

"Maybe you ate them," said Sam.

"No, I didn't."  I stopped chewing, thinking about all of the fries I'd eaten.  But I was still hungry...And it wasn't like I could order anything myself, given that no one could hear, see, or feel me.  Interesting how I could move objects but not people.  What was I, some kind of ghost?

I stole a chicken tender, from Sam's plate this time, to be fair.  That one chicken tender turned into three.

"Dean, if stealing my chicken is payback for your fries..."

"I didn't take your damn chicken tenders!"

Maybe I should stop.

I wasn't hungry anymore, so why take more of their food?

"...you sure we should be here?  This isn't exactly the place for an angel..."  A female voice caught my attention.

"She is here, isn't she?" said another, this one a male voice.

"Well, yes.  I'm just not sure if we should."  I searched for the sources of the voices.

"She needs our help, and--"

"If helping this girl is a way for you to somehow fix your mistakes, you--"

"I'm not trying to fix my mistakes, Hannah.  I know what I did."

I finally found them.  Hannah and Castiel were standing near the doorway.  Relief washed over me.  They heard me.

Castiel and I made eye contact.  Eye contact.  That meant that he could see me, too.

Thank God.

Castiel hurried to where I was sitting, Hannah trailing behind.

"Cas?" Dean said, spotting him and pointing at his chest.  Sam whipped around.  "You were stealing our food."

"I...your food?  I didn't steal your food," Cas said, confused.

"What is going on?  Why are you here?  How did you find us?" Sam asked.  They spotted Hannah.

"I heard a prayer," Cas said.

Dean scrunched his eyebrows.  "I didn't pray... Sam?  Did you...?"

"No."

Cas and Hannah looked at me.

"What are you looking at?" Dean asked.

"Who am I looking at, actually," Cas said.

"What?  There's nobody there."

Cas reached out to me and touched my forehead.  I felt a surge of energy flow through me, and then Sam and Dean both widened their eyes, which had finally landed on me.

"Wha--who are you?" said Dean.  Sam shook his head side to side rapidly in confusion.

"I, uh," I said.  "I'm Nicole?"
