A/N: I hope you will all enjoy this chapter! I've decided to give this story another go, so please if you want to see more leave a review:)

They soon figured out the reason that Skynet was so interested in Barbara Chamberlain was because she was designing a program that would link all the traffic cameras to a data centre in City Hall. The machines would be able to know where everyone was, always. Kat and Derek decided to scout out the location and see if there were any weaknesses in the defence.

"There's no way we're going to get through all that security" Kat stated, after they had sat down at a café across the street.

"Don't worry, we won't be going through the front door. These buildings are all connected by a series of underground tunnels during the Cold War. I did a project on them in the 9th grade…my last year of school" Derek explained.

"I'm sorry" Kat mumbled.

"For what?" Derek frowned.

"Your childhood got cut short…you never had the time to grow up" She pointed out.

"There's never any time" Derek sighed.

"When did you learn all about this?" Derek asked.

"I was eight…I guess being that young actually made everything easy to believe. The machines, the end of the world…in my eight-year-old head it didn't seem farfetched" She told him.

"That's when you met Pete?" Derek guessed, as she nodded.

"Growing up with him must have been…different" Derek went on.

"Things were simple when I was with my dad. Protect John and Sarah Connor. That's all there was to my life. They never really seemed like people…more like Gods I guess" She chuckled.

"When did you meet them?" Derek questioned.

"Near my sixteenth birthday. My dad had finally contacted them a few months earlier, and I got so desperate to finally meet the legends in the flesh…He was pretty mad at me, it was stupid" She sighed.

"How mad?" Derek couldn't help but ask.

"How'd do you know the tunnels are still going to be there?" Kat inquired, clearly wanting to change the subject.

"I lived there. Kyle and I. After they dropped the bombs on us" Derek admitted, shocking Kat.

"…That must have been awful" She frowned, not really knowing what to say.

"We were alive" Derek shrugged.

Once they got back, John quickly informed them that he had found the footage of how the Terminator had found out about Derek's group. He had simply spotted that Barbara was being followed. Cameron had no part in it. John was reluctant to show Derek the violent scenes of his friends being killed, but the older man insisted on it. Kat grimaced as the Terminator crouched down beside the man he had just killed, clearly so unaffected by it.

"Sayles was always, uh…I loved him, but he was an idiot sometimes. He was careless" Derek sniffed, seeming close to tears.

Kat wanted to comfort him in some way, but she knew he wasn't the type of man who would appreciate that.

"So, you were following Barbara Chamberlain too?" John inquired.

"No. I didn't know he was. There were a lot of leads. We spent a lot of time on our own…I didn't know" Derek mumbled, as he got up and left the room, not looking at Cameron as he walked past her.

"It's okay to be upset you know" Kat stated, when she followed Derek to the living room where he was packing a bag.

"I'm not going to breakdown if that's what your worried about" Derek responded.

"I'm worried at you" She said, emphasising the word.

"I'm fine" Derek insisted.

"It's not good to bottle things up-" She began, but he cut her off.

"Just like you're not bottling things up about Pete? Why don't you want to talk about him, huh?" Derek challenged.

Kat opened her mouth to argue, but the words died in her mouth. She turned on her heel and left, angry that Derek had been there for such a short time and already seemed to be putting things together.

"Are you sure you shouldn't wait for mum?" John suggested, an hour later, as Kat and Derek were ready to sneak back into City Hall.

"We have no idea when she's coming back" Kat pointed out.

"This is dangerous, Kat" John went on.

"Our whole life is dangerous" Kat rolled her eyes.

"They'll have guns" John stated.

"I'll be careful. Don't worry your little head about it" Kat mocked, ruffling his hair, and walking over to Derek who was packing the car.

"You're not coming" Derek told her.

"Like hell I'm not" Kat scoffed, throwing her bags in the back.

"I told Sarah I'd keep you safe" Derek insisted.

"I don't need your protection" Kat scoffed, as she got into the car and waved goodbye to John and Cameron.

"Are you sure you know where you're going?" Kat asked, as they wandered down the tunnels.

"Well I should. This is where I lost Kyle to the machines when we were kids" Derek admitted, looking at the spot with sad eyes.

"And being down here doesn't effect you at all?" Kat questioned.

"We need to keep moving this way. There's an elevator shaft" Derek exclaimed, turning left.

"So, are you just going to ignore me now?" Kat went on, as Derek came to a halt.

"There shouldn't be a wall here. In the future there's no wall" Derek announced.

"It must have already been destroyed" Kat suggested, as she touched the wall.

"We're gonna have to blow it up" Derek replied, taking out two explosive devices.

"You're kidding, right?" Kat asked, with wide eyes, as Derek placed them both on the wall.

"C'mon" He said, pulling her around the corner.

Before she could say anything else, he twisted them around so that her back was to his chest and placed his hands over her ears. A moment later there was a massive explosion which sent debris flying everywhere as Kat flinched. After a few more seconds the sound began to die down and Derek took his hands away from her head and looked around the corner to check that the tunnel was still stable.

"You enjoyed that a little, didn't you?" Kat suggested, seeing Derek's exhilarated face.

"Only a little" He shrugged, with a small smirk.

"Alright, so what next?" Kat inquired, as they looked through the crater they had created.

"Now we abseil" Derek responded, as he threw two ropes down with weights at the bottom.

"…Your kind of crazy, has anyone ever told you that?" Kat teased, as Derek let out an amused sound.

"You said you were up to this" Derek pointed out, handing her a belt that she could attach to the rope.

"…I am. But you can go first" Kat replied.

Soon Derek had attached his own belt to the rope and was getting ready to climb down when he saw Kat was having trouble just connecting her belt. There were so many clips that needed to get attached into the right place. He walked over to her and undid everything she had started, pulling her closer to him to do so. Kat quickly became aware of just how close they were as she could feel his breath across her shoulder and shivered lightly. He was done in a matter of seconds, and soon they were both abseiling down, which Kat found she enjoyed more than she expected.

"That was awesome" She grinned, as this time she was able to undo the clips by herself.

"You did pretty good…for a beginner" Derek told her, a teasing tone in his voice.

"Yeah, well we can't all be James Bond" She retorted, with a smirk.
