The four of us were in front of the TV watching the security tape. Dean was on the arm of the couch, Bec was sitting on the couch, I stood watching, and Sabrina sat on the floor. There was plenty of room on the couch but she insisted on the floor.

"Here he comes."

Zack went in to his house.

"22:04, that's just after ten. You said time of death was about 10:30." Dean commented.

"Our lawyers hired some kind of video expert. He says the tape's authentic. It wasn't tampered with."

Brie straightened up as I noticed it as well.

"Hey, Bec, can we take those beers now?" I asked.

"Oh, sure." She got up to go to the kitchen.

"Hey." Sabrina called and she turned around. "Maybe some sandwiches, too? Please?"

"What do you think this is, Hooters?" She smiled before leaving.

"I wish." Dean said getting up.

"What's a Hooters?" Sabrina asked.

I chuckled quietly as she looked at us with a look a curious child would have. Again, innocent.

"Nothing you need to worry about sweetheart." Dean told her as he stood in between us. "What is it?"

"Check this out." I said rewinding then replaying the tap at one of the frames showing Zack.

It showed Zack looking directly at the camera. His eyes were silver. I paused it on the frame.

"Well, maybe it's just a camera flare." Dean suggested.

"That's not like any camera flare I've ever seen." Brie and I said.

"You know, a lot of cultures believe that a photograph can catch a glimpse of the soul." She added on.

"Right." Dean muttered.

"Remember that dog that was freakin' out? Maybe he saw this thing. Maybe this is some kind of dark double of Zack's, something that looks like him but isn't him."

"Like a Doppelganger."

"Yeah. It'd sure explain how he was two places at once." Brie nodded.

~S~

I was up thinking through a few through thoughts when there was a knock on the motel door. I looked at Dean seeing he was already asleep so I got up answering to see Sabrina.

"Can't sleep either?" She asked.

I shook my head.

"Come on."

I moved and she came into the room sitting at the table. She crossed her arms on top of it before putting her head on top of them.

"How you holdin' up?" I asked closing the door then sitting across from her.

She shrugged.

"Better I guess. Just ridin' the waves of emotion."

I chuckled at what she said.

"I looked it up." She muttered.

"Looked what up?"

She looked where Dean was then me.

"Hooters."

I tried to contain my laughter. It didn't surprise me she looked it up but the fact she looked up something like that was funny.

"You wouldn't tell me what it was." She complained.

"And now you know why."

She grumbled under her breath turning her head from me. I chuckled as her hair fell in front of her eyes and she frowned at it.

"So, what is your opinion on this case?" She asked pushing her hair away.

"I don't know. I haven't seen anything like it before."

"Well since we're up, we should think shouldn't we?" She told me sitting up straight now.

"Sabrina, you should sleep."

"Sleeping is for non-hunters." She crossed her arms.

"Brie."

"I'm not sleeping unless you do and I know you aren't."

I sighed. We were just both incredibly stubborn that way.

"Ok, I guess we can think about it."

"So, the killer entered the house at ten thirty. Zack was with Rebecca." Sabrina started putting her elbow on the back of the chair.

"The dog and the camera caught something that wasn't there."

"Should we test Zack? Maybe he was possessed or something." She suggested.

"Possessions are rare as they are. With just this one incident and as small as the count it is, I don't think it would be a demon. Besides, it was still two places at once."

She nodded as I talked thinking through more.

"Well, if it is a dark double as you put it, then they had to leave and we only have Zack going in." She went through leaning across the table as she did.

"And the police would have never pursed a trail." I agreed.

"Because they thought they had Zack." We both finished.

"So there has to be another trail to follow." I nodded.

"We could head out now if you want." Sabrina offered pointing to the door.

Instead of saying sure I yawned stretching my arms. She smiled at that.

"Or we could sleep and wake up early to investigate with Dean."

"Yeah, that's probably best."

"I'm going to my room then." She said standing and I did too. "If you need me, you know where I will be."

She started to leave when I couldn't stop myself.

"Actually, can I join you?"

She looked back at me the smiled before nodding.

"I don't mind. Just let me change first."

She left and I sighed. I knew I really shouldn't but I couldn't help it more lately. I tried to stop a few days ago but it was just so comfortable even with the crap beds and I enjoyed it more than I should. Though Brie didn't complain and it was an ok arrangement for both of us so I knew I wasn't going to stop for a while.

~S~

The three of us got out of the car Sabrina drinking her cup of coffee with Dean doing the same.

"Alright, so what are we doin' here at 5:30 in the morning?" Dean asked.

"We realized something. The videotape shows the killer goin' in, but not comin' out." I told him.

"So, he came out the back door?" He asked.

"Right. So, there should be a trail to follow. A trail the police would never pursue." Sabrina explained looking one way while I looked the other.

"'Cause they think the killer never left. And they caught your friend Zack inside."

I didn't catch what he said at the end as I looked by a dumpster.

"Sam." Sabrina called.

I looked up and she was by a telephone pole smeared with blood.

"Blood. Somebody came this way." She said.

"Yeah, but the trail ends. I don't see anything over here." Dean told us.

Now a siren was going off as an ambulance drove past us, and we all exchanged a look.

"Let's get a move on."

Sabrina took off in a sprint her hair flying behind her. I shrugged to Dean quickly following her. I caught up quickly to her when she suddenly skit to a stop in front of a crime scene. Dean was not far off from behind us as we watched an Asian man get handcuffed and was stepping into a police car.

"What happened?" Sabrina asked a woman.

"He tried to kill his wife. Tied her up and beat her."

"Really?" I questioned.

She nodded.

"I used to see him going to work in the morning. He'd wave, say hello. He seemed like such a nice guy."

We watched him get taken away then went to the side of the house to look for another escape route. I looked on the side of the house as Brie looked inside two garbage cans but she looked up shaking her head. We moved to the front of the house, where Dean called out to us.

"Hey." We both turned around looking. "Remember when I said this wasn't our kind of problem?"

"Yeah." We nodded.

"Definitely our kind of problem."

"What'd you find out?"

"Well, I just talked to the patrolman who was first on the scene, heard this guy, Alex's story." He said pointing behind him. "Apparently the dude was driving home from a business trip when his wife was attacked."

"So, he was two places at once." I said.

"Exactly. Then he sees himself in the house, police think he's a nutjob."

"Two dark doubles attacking loved ones in exactly the same way." Sabrina said crossing her arms.

"Could be the same thing doin' it, too."

I thought about it for a second.

"Shapeshifter?" Dean shrugged. "Something that can make itself look like anyone?"

"Every culture in the world has a shapeshifter lore. You know, legends of creatures who can transform themselves into animals or other men." Sabrina threw out.

"Right, skinwalkers, werewolves." Dean agreed with her. "We've got two attacks within blocks of each other. I'm guessin' we've got a shapeshifter prowlin' the neighborhood."

"Let me ask you this—in all this shapeshifter lore, can any of them fly?"

"Not that I know of." She shook her head.

"We picked up a trail here. Someone ran out the back of this building and headed off this way." I told Dean.

"Just like your friend's house."

"Yeah. And, just like at Zack's house, the trail suddenly ends. I mean, whatever it is just disappeared."

He thought for a moment.

"Well, there's another way to go—down."

All three of us looked down and noticed a manhole.

~S~

I climbed down as Sabrina closed the manhole. I looked around behind me when I heard her shriek then hiss. I quickly turned around to see her putting a hand on her head.

"What happened?"

"I slipped a little and hit my head on the ladder."

"Here. Move your hand."

She did and there was a small bruise.

"It's going to be bruised for day or two but you'll be fine."

She nodded and both of us now looked around the sewer system.

"I bet this runs right by Zack's house, too. The shapeshifter could be using the sewer system to get around." I said.

"I think you're right. Look at this."

We bent down and examine a pile of blood and skin on the ground. Brie put a hand over her mouth as Dean took out a pocketknife and took some on it.

"Is this from his victims?" I wondered out loud.

"You know, I just had a sick thought. When the shapeshifter changes shape—maybe it sheds." Dean suggested.

"That is sick." Sabrina nodded.

~S~

Dean opened the trunk.

"Well, one thing I learned from Dad, is that no matter what kind of shapeshifter it is, there's one sure way to kill it." He said taking out bullets and a gun.

"Silver bullet to the heart." I grinned.

"That's right."

"Sam." Sabrina said and I looked over at her. "Can I talk to you?"

I nodded going away from Dean her following.

"Sam, this is hitting home a little." She muttered.

I remembered now in her own way dealt with a werewolf not long ago.

"Hey, if you want to sit this one out?"

"No…I just…"

"Sabrina. Dean and I, we can do this." I promised her taking her shoulders. "If you want to sit and the car while we go in the sewers you can."

She looked around then nodded.

"Yeah. I think I will."

"And that's ok." Now my cell rang. "Go tell Dean while I get this."

She left and I answered my phone now.

"This is Sam."

"Where are you?" Becca asked.

"We're near Zack's, we're just checkin' some things out." I said looking over at Dean and Sabrina seeing her quietly explain. Surprisingly Dean nodded saying it was ok.

"Well, look, Sam, just stop, 'cause I really don't need your help anymore."

"What are you talkin' about?"

"I told the lawyers that we went to the crime scene."

I scoffed.

"Why would you do that?"

"Well, I told them that we were with police officers. And they checked it out, and they told me that there is no Detective Sabrina or Dean Winchester."

"Bec—"

"No, I don't understand why you would lie to me about something like that."

"We're tryin' to help." I said as Sabrina came over now looking confused.

"Oh, trying to help? Do you realize that that was a sealed crime scene? This could have just ruined Zack's case."

"Bec, I'm sorry, but—"

"No, goodbye, Sam."

She hung up. Sabrina put a hand on my arm giving me a sympathetic look as Dean came over.

"I hate to say it, but that's exactly what I'm talkin' about. You lie to your friends because if they knew the real you, they'd be freaked. It's just—it'd be easier if—"

"If I was like you."

"Hey, man, like it or not, we are not like other people. But I'll tell you one thing. This whole gig—it ain't without perks." He told me holding out a gun.

I took it and put it in the back of my jeans. I looked at Sabrina.

"You going to be ok?"

She nodded.

"Gun in my pocket too."

"Ok, we'll be back."

"Good luck. Kill me a shifter."

"That's what we plan to do sweetheart." Dean told her before we walked away.

~S~

Sabrina's POV
I sighed leaning back on the seat. Sam helped a lot. I was actually getting better. I even had enough confidence to tell Dean because of him. This case though, it was shapeshifters. A close enough relative to a werewolf to freak me out. The guys had it though, I knew they did.

Now I saw a shadow outside. I sat up slowly looking out. There was nothing. I took my gun out checking the clip before putting it in my pocket and getting out. I looked around quietly knowing it was not the boys. If the shifter had been this close, I would have heard the gunshot.

I heard the crunch of the ground behind me and I whirled around gun ready but I was knocked on the side of the head out cold.
