Dean Winchester's Worst Fear

A/N: Hi, everyone! This is my first Supernatural fanfic… so please read and review with what you think. I am open to any constructive criticism that you want to give me as a writer. This takes place soon after John's death in Season 2 so there are no spoilers for any recent seasons, but I would not recommend reading this if you haven't seen Season 2. This also changes some details in the Season, just so you know. I hope you enjoy!

Disclaimer: I do not own Sam, Dean, John, Ellen, Jo, Ash, Cas, Crowley, Bobby, Alastair, Lucifer, Meg, Jessica, or any other characters that you might see in this fan fiction. (Not all characters mentioned are in the fanfic.)

Dean walked back out to his now demolished car to re-repair it after he demolished it with a hammer. His father's words echoed in his head, "You have to save Sam, Dean. You have to… And if you can't save him, Dean, you will have to kill him." He knew that he had to save Sam, protect Sam. His dad never needed to tell him that. John had pounded into his head a million times how important it was to take care of Sam. It wasn't only his job. It was Dean's life, his only purpose. Dean knew that he couldn't fail. When it came down to it, he wouldn't kill Sam. He couldn't. He spent nearly a month of repair work every day until the Impala was back in its perfect condition, and every day he worried about his little brother, Sammy.

Of course, Sammy wasn't really little any more. He could take care of himself. Dean needed to stop worrying about him. While contemplating this in the Impala, Dean stops off at a motel in the small town of Jasper, Michigan. They check in for the night using credit cards under the fake names of Dave and Bob Hope, Dean being Dave and Sam being Bob. The room's cheap lamplight cozily glowed over economy bedspreads and two queen sized box spring mattresses. Dean crashed immediately on the one bed, while Sam stayed awake, contemplating his dad's death, with a bad feeling. Dean wasn't telling him something, but what? All of a sudden he had a pounding headache! A girl screamed as some monster stripped off its skin and morphed into the girl. Sam opened his eyes. Dean was now awake and staring intently at him as if asking him what was wrong.

"Another vision, a blonde haired woman about my age was screaming as, what I think was a shape shifter, turned into her. I don't know," Sam quietly told Dean, trying to remember every detail.

"Where was she?" Dean asked, hoping that they could save her and worrying that something was seriously wrong with his brother.

"A back alley, somewhere close, like in this town, but I don't think that anything has happened to her yet. It's just that I have this feeling, like we have time to stop this," Sam assumed.

"Well, she'll have to be safe until tomorrow," Dean concluded, "'cause no one's going to be up in the middle of the night and we don't even know who or where she is."

Neither brother slept any more that night, for they were too worried about this mysterious woman. Sam said that he thought she was safe for now, but he didn't say for how long she would continue to stay safe. Sam mulled over the woman all night, although Dean was more worried about his little brother's safety. John's last words lingered in his mind, "If you can't save him, you will have to kill him."

At six A.M. the next morning, the brothers decided to go get some breakfast and look for this woman. They walked into the small diner across the street, which was just opening for the day, and sat down at a small booth in the corner.

A few minutes later, a waitress came to take their order, "Hi, my name's Melody and I'll be serving you today. Are you ready to order?" She had to ask, but she already knew what the boys would be ordering and started writing.

"Yeah," Sam stated, reading off his menu, "I'll have some whole grain waffles with fruit and sugar free orange juice." Sam looked up at her, for the first time really seeing what she looked like. It was the woman from his vision! Sam froze for a second staring at her then quickly regained his composure. He didn't even listen to his brother's order. Instead he waited for Melody to leave so he could talk to Dean about saving her.

"Hey, Dean," Sam whispered urgently, as Melody strolled away, "That's her, the girl in my vision."

"You're sure?" Dean asked.

"Yeah, I'm sure. That was her," Sam answered excitedly. "We have to do something to help her."

"You said that a shape shifter attacked her, right?" Dean asked uncharacteristically cautious.

"Yeah. Why?" Sam asked back, trying to figure out what Dean was trying to tell him.

"Sam, usually your visions have something to do with the demon," Dean whispered, still cautious, "This time there were shape shifters involved. Doesn't that seem a little weird to you?"

"Yeah, I guess. But Dean you're missing the purpose here. This girl's in trouble and we can save her."

Melody came back cheerfully with their meals and went back to work with neither brother knowing that she could hear their thoughts from the former conversation.
