I had completely run out of fan-fiction ideas, and was looking around my room for inspiration when my eyes stopped upon a photo-mosaic of Legolas, and I decided that a person seeing their own poster if they aren't supposed to even exist, would be very odd. I hope this is enjoyable!
"It looks all pixilated." Sam said.
"Nah, it's made up of little pictures." Dean replied, leaning in closer.
"You're right! Is that me drinking Ruby's blood?" Sam gaped in awe.
"Don't remind me of that." Dean answered flatly. "Holy shit! That's you killing Lilith!"
"And starting the apocalypse. And that's when I first met Cas. Wow, THAT was painfully awkward."
"Hey, boys, are you looking to buy or are you time wasters?" The Winchester brothers turned to see a large man looking at them with a rather displeased expression and folded arms. He must work here in the bookstore.
"Yeah, uh, we were wondering... who is this?" He pointed to the poster.
"That's Sam, drawn from his descriptions in the Supernatural series by Chuck Shirley. The poster is made up of little pictures of Sam's deeds."
"Ah, I see." Sam looked very uncomfortable.
"Oh. Right. Is there, uh, one of Dean?" Dean asked.
"Not here." Was the reply.
"Oh, very good, very good. So uh, yeah. We'll just be off now." Dean and Sam left in a hurry.
"Oh no, people BUY posters of me?" Sam groaned once they were away from the bookstore.
"Nah, it barely even looked like you." Dean said, biting his lip to keep from laughing. Of course, there was some of him floating around too...
"What? Were we looking at the same poster? It looked EXACTLY like me! Oh no. I'm famous and people don't even know that I really exist!" He moaned again.
"When we find Chuck again I am so gonna kill him." Dean sighed. "And how come MY poster wasn't on display?"
"I'm hotter." Sam laughed.
"Are not!" Dean answered.
"Jerk."
"Bitch."
