A/N: After this one only three more chapters to go!

Also, I feel like I've been lied to, because after a little research on infrared, I found out that you really can't see through walls and the heat signatures only show white and grey. LAME. So I made it cooler here!

Nerd on!


Chapter 8: Sam

Sam was sitting at Felicity's computer, stewing over the fact that he wasn't going on the hunt tonight. Logically he knew he shouldn't go. He was in too much pain and he would either slow everyone down or maybe even get himself killed. But letting Dean go on a hunt without him for backup, no matter how good Oliver and Diggle were, went against every fiber of his being. His cell phone rang and brought him back to the present. Well one of his phones rang. He pulled out two from his jacket, checking the screens. Both were blank. He pulled out the third from his back pocket. The screen lite up and the caller ID said: Blocked.

He raised it to his ear cautiously. The only two people that really had this number were Dean and Bobby. "Hello?"

"Hi Sam, it's Felicity. Digg and I are on our way down. Digg seemed to think we should warn you or else you'd shoot us or something."

"Felicity? How'd you get this number?"

"Spoilers, Sam. Spoilers!" She replied in a sing-song voice.

"Did you just quote Doctor Who?" Sam asked.

"Hey-yo! Digg, we got ourselves a closet nerd in a 6'4 frame!"

The Arrow Cave's door opened and Sam spun in the chair to see Felicity and Diggle walk in. "You know you're the first person I've met in a while that actually got one of my nerd references. They always go right over Oliver and Digg's heads," Felicity said, bringing her hand up and over her head quickly. She was dressed down, in jeans, a sweater and sensible shoes. Dean will be so disappointed. She and Digg started down the stairs.

"Oh, I get them Felicity. I just pretend not to. Otherwise Oliver and I would be bombarded with Lord of the Rings or Harry Potter quotes all day, everyday." Diggle said not meeting her eyes.

Felicity scoffed. "I would not!"

"Oh really? Did I not hear you say last week, "There is no curse in Elvish, Entish, or the tongues of Men for this treachery" when Oliver tried to update a system without asking you?"

"Okay! One time!"

"What about all the times Oliver wants to head out without a plan and you quote, "One does not simply walk into . . ." whatever building that night's Baddie is hiding out in.

The Arrow Cave door opened and Oliver and Dean walked in, both carrying full black duffle bags over their shoulders.

Sam, Diggle and Felicity glanced up and watched them walk down. All of them kind of surprised they survived being alone together.

Felicity looked back at Diggle and sneered. "That one shouldn't count! Because it's true! One does not simply walk into any situation, without being prepared!"

"A day may come when the courage of Men fails. . . but it will not be THIS day!" Dean quoted at the bottom of the stairs and brought a fist up like he was holding a sword.

Talk about closet nerds, Sam thought. His brother was pop culture reference king. Felicity and Diggle looked more surprised at Dean's recital than they did about hearing of vampires.

"What? I've seen the movies! Aragorn is the shit!" Dean said incredulously. Felicity and Diggle began to laugh at him, Sam ducked his head and hid his smile. "What? Dude was a Ranger. Practically the same thing as a Hunter!"

Sam couldn't hold his laugh. "Shut up Sammy."

Oliver interrupted their laughter with, "Did you fill Dig and Felicity in on tonight?"

Sam cleared his throat, feeling a little chastised. "Um, no, not yet. They got here just before you guys."

Felicity rolled another chair over near Sam and sat down. "Right. Let's hear it then!" she said, her joking manner gone.

"They're going to hit right after sundown. If they are Vampires, they might still be sleeping -"

Felicity cut him off. "They? You're not going?"

Sam sent a sarcastic smile over to Dean. "No. I am not." Then he looked back to Felicity, "Hope you don't mind me hanging with you a little longer?"

Felicity picked up on the tension between him and his brother. Atta girl. "Oh, no! Not at all!"

"Thanks. As I was saying. Hit right after sundown, there's a possibility that if they are vampires, they'll still be sleeping." Sam spun the chair and brought up the warehouse plans. "Dean will come in from here on the third floor and confirm that whoever is in there, is indeed vamps and radio to Oliver and Digg." He then filled in Felicity and Diggle on the rest of the plan. Sam knew he was being a little controlling. But he needed to help in some way . . . and when it came time for Dean, Oliver and Diggle to head over, he'd relinquish control back to Felicity. He looked at her to see if she was taking his control over her computer personally. Didn't look like it, she was leaning back in her chair, arms crossed listening.

"Right. Well, the warehouse's security cameras are only on the first floor. I won't be able to help you out on the second floor or above. Which, I'm not the biggest fan of. . ." She brought a hand up to her face and cupped her chin, in what must be her thinking pose. She looked at Sam and then Dean. "Would vampires come up on infrared cameras? Or would that whole part of them being technically dead, you know, hinder heat coming off them?"

Sam looked at his brother, Dean had a look on his face that was probably the same as on his own: The Huh-how-have-we-never-thought-of-that-before look. "I have no clue. Yes, they are technically dead and none of their own blood is pumping in their bodies. . . but I don't know what that would look like on infrared. We've never had that technology available to us before."

Felicity smiled at him, then scrunched her nose up. "Neither have we. . . technically. But the government has been nice enough to lend it to us once or twice before. Not that they really knew they were lending it to us. . ." She slid her chair closer to the computer and lifted her chin to it. "Do you mind?"

"No. Sorry. It's yours anyways." Sam scooted left and gave her room.

She worked her magic and brought up a map of the U.S., then zoomed it all the way into Starling City, then to the street the warehouse was on, then to the warehouse itself.

Dean took a few steps forward and leaned down for a better look. "Did you just- Did you just hack a government satellite?" He stuttered out. Sam felt just as amazed.

She turned her head and looked up at Dean with a proud little smile. "As I said. We don't have that tech either. But the government does, as much as they don't want the public to know!" She turned back to the computer, "Now, normal infrared doesn't even allow you to see through walls and is shown in greys and whites. But this, my friends is some Grade A military magic! We'll not only be able to see through walls, but also a better depth of thermal energy. . .There. One, two, three. . ." she started counting in her head. "Ten, shapes that could be vampires, because those are definitely not the normal heat signatures humans put off. And it looks like the place is totally clear of humans."

Sam was already impressed with Felicity's computer prowess from her display last night. But this. . . this was something else.

"You know. If you ever get caught for all these government hacks, you might have a rap sheet as long as mine!" Dean said happily. Felicity's face fell and she glowered at him.

Oliver spoke before she could retort. "You're sure that those aren't normal human heat signatures?"

"Yes. With this tech, normal vanilla humans would show up bright red-orange. These guy's are showing white. Working machinery would show up as grey and then descend into blues. Plus, look at how the white spots are spread out. Look's like lines of beds to me, with two in this separate room. That follows a nest's patterns, does it not? With the "master" and his mate separate?"

Sam raised his eyebrows, Felicity wasn't only good with computers, she was a quick learner too. And again he thought how much easier his and Dean's lives would be if they had someone with Felicity's skills on their team.

"Best case, you guys go in and find machines or whatever in those patterns. Worst case, those are vampires," Sam said to the guys. "But the fact that we'll be able to see if these things move. . . Game changer." He looked at Felicity. "Man, you really are good. Dean and I might be calling you up in the future."
