They had only been gone for a few minutes when everyone was sick of the idea of being gone. Jo had accidently bumped Dean, who quickly and quite vocally reminded them that he still had a broken arm and it hadn't been set yet. Jo had a massive headache from her fall in the bathroom, which didn't help her appetite during their short meal. And Sam was too preoccupied by both his brother's predicament and his own pain and confusion to really be bothered by eating. The whole idea was good but useless, and the three soon gave up. It was, in fact, on their way home to rest and recuperate that things started spiraling downhill.

Sam felt an all-too-familiar pain building behind his eyes and squinted in the passenger seat of the Impala.

"Oh, crap," he muttered, leaning his head back. "Not good."

Dean risked a glance over, but the movement made him wince at jostling his arm. "What?" he ground out.

Sam didn't answer, just rubbed the bridge of his nose in a failing attempt at relieving some of his agony. Dean looked over again, more carefully this time, and saw his brother's condition.

"Vision?" he asked aloud. Sam managed a nod in return, inhaling quickly at an especially bad wave of pain.

"Vision?" Jo repeated. "This is what happens?"

"Yeah," Dean answered grumpily.

"What do you do?"

"I get to sit here and watch Sammy suffer," he growled. "That's what I do."

Sam gasped as the vision hit him full force.

-

A woman wandered through the cabin, looking in every single room. There were signs of a struggle in the front room, as well as a devil's trap drawn in blood on the ceiling above the couch. But there were no people.

She finally made it to the bathroom, where Dean, Sam, and Jo were all unconscious. She smiled evilly as she looked down at their helpless forms, and turned to go back to the front room. When she got there, she added a symbol to the devil's trap.

"That ought to keep him in," she said as she got down.

-

Just as quickly as the vision hit, it left. He was breathing heavily from the effects, holding his head in his hand, pondering what he'd just seen.

"Sam?" Dean asked from the driver's seat. "You done?"

"Yeah," he choked out, sounding hoarse.

"What happened?" the elder Winchester asked. "Tell me what you saw."

"Dean, I saw the symbol being added to the devil's trap."

There was a pause as the other people in the car digested this. "What?" Dean finally said.

"I saw something that already happened, Dean."

"That's unusual."

Sam rolled his eyes. "I'm seeing the past now and all you can say is that it's unusual?"

"Dude, what do you want me to say?"

Jo interrupted. "How did it get there?"

"What?"

"The symbol, Sam. Who put it there?"

The younger hunter sat back. "There was a woman in the cabin. I saw her go looking for us. She found all of us unconscious in the bathroom. And then she went back into the living room and put up the symbol."

"A woman? Who was she?" Dean asked.

"I don't know. I just saw her do it. I generally don't get names associated with visions."

"Sometimes you do."

"Yeah, well sometimes I see things that haven't happened yet, too! This isn't one of those times!"

Sam huffed in frustration and Dean turned his total attention on the steering wheel. Jo raised her eyebrow at their reaction to each other, but, once again, wisely decided to say nothing. She figured it was in her best interest to let them cool off and work it out with each other before trying any communication with them.

They finally made it back to the cabin and all three got out of the car. Dean snatched up his shotgun and headed for the door. Sam stopped when he saw what his brother was doing.

"Dean," he said.

"What?" Dean snapped, without turning around.

"What are you going to go kill?"

"Sammy, you said you saw a woman in there painting the symbol on. Who's to say she left?"

"Wouldn't we have noticed her?" Jo asked softly.

Sam shrugged. "I wasn't exactly looking for a person in the cabin. A lot could have escaped me."

"Me too," Dean put in. "What a stupid, amateur mistake to make. We should have checked everything."

Sam grabbed his gun, checked the clip, and stalked past his brother, which was quite a feat, considering the pain that still radiated from the wound in his thigh. "Well, let's check everything now."

Dean growled quietly at the idea of Sam going in first, where clearly there was already someone who had it out for him. Shaking his head, he followed the younger Winchester into the room, eyes roaming immediately up to see if something had been added to the devil's trap. It was as they had left it.

Sam, meanwhile, had already gone through to the kitchen and was walking down the hall. He gave the bathroom a cursory glance and continued on without stopping or even slowing down. He went into the room he used and checked it over, but nothing seemed out of place. By the time he was heading for Dean's room, Dean and Jo were on their way, as well. Sam stepped into the room and immediately knew something was wrong. There was a chill in the air and he felt like someone was watching him.

"Dean?" he whispered.

"You feel that?" Dean asked, instead of answering as he sidled to be right next to Sam.

"Yeah."

Their eyes scanned the room, but they could see nothing. "Tell me you can check for EMF right now," Jo said from her spot in the doorway.

"No need," Sam replied. "We already know it's here, and that won't help us to know exactly where it is."

"You want to try to cell phone thing?" Dean queried. "It worked before."

"I don't particularly want to take my hands off of my gun at the moment, but thanks for the offer."

Dean nodded. "Okay. Then are we just going to stand here all night, or are we going to do something?"

"I can't stand here all night," Sam groused. "I'm exhausted."

"You spent the whole day on the couch, dude! How can you be tired?"

Sam risked a glare at Dean, his attention off their current hunt for a split second.

And it was a split second too long.

Dean watched in horror as something seemed to slam into his brother, taking Sam off his feet and into the door. The gun dropped from Sam's hand, and as Dean raised the shotgun to fire at absolutely nothing, his arm protested. His gun also dropped to the floor, and he bent for it, cursing. The supernatural form in the room flew into his unprotected, half-stooped body , taking him all the way across the room. He lost consciousness when he collided sharply with the wall, crashing down on a shelf and not moving.

By this time, Sam had gained his feet and his gun and was staggering in Dean's direction. He stopped dead in his tracks as, half way across the room, the woman from his vision materialised in front of him. His gun was pointed at her head before she was fully substantiated.

"You," he hissed.

She grinned. "I finally have you, Samuel Winchester," she said with a sneer. "And nothing can stop me now."

"Who are you?" he asked, gun raised to point at her head.

"Who I am does not matter," she replied. "What is more important is that the trap I created was successful."

"Why now?" he spat out angrily. "Why not when I was trapped on the couch, alone?"

She laughed a bit before looking back at him. "Oh, my dear boy, the trap wasn't for you."

Sam cocked his head in utter confusion at her statement. "What?"

She tossed her head behind her in the general direction of where Dean lay, unmoving.

"It's for him."
