"Bullet nicked his left lung. I got a fragment lodged in the soft tissue, I can get it out, but will someone please tell me what the hell is going on around here?" Charley insisted.

"She's a machine! She's a liar!" Derek cried, trying to sit up, seeing Cameron in the corner of his eye.

"Sedative, my bag!" Charley yelled behind him.

Kat had moved into position at his other side, and tried to hold him down by his shoulder. She knew the more he moved the worse his injuries would become. Sarah took a step back, becoming frozen in her place. Kat knew it must have been a shock for her, finding out that the man she loved had a mystery brother she'd never hears about.

"She's a liar! Everything she says is a lie! Don't listen to her!" Derek exclaimed, as he grabbed onto Kat's leather jacket.

"Don't listen- don't! Don't! Get that bitch away from me! No, no! Get that bitch away from me!" Derek begged, as he saw Cameron preparing the sedative.

Kat took his hand in her own, as he held onto it tightly, seemingly seeing it as a tether to reality. He looked towards her with pleading eyes, with confusion mixed in.

"Cameron, pass Charley the syringe" Kat told her, as she approached.

However, Cameron acted like she hadn't heard this and loomed above Derek.

"Get away from me! No!" Derek shook his head.

"Hey, it's okay. She's not going to hurt you" Kat promised, squeezing his hand.

"Do you want him to die?" Charley accused, as he grabbed Cameron's arm to stop her from injecting him.

"If I wanted him to die-" Cameron started, but she was quickly cut off.

"Cameron! Please, just go" Kat insisted, as Charley injected him with the sedative.

"Mum, come on, what can I do?" John questioned.

"I need a manual aspirator. To drain the lung, okay? It's in the back of my truck. You know what it looks like?" Charley asked John.

"Yeah, I remember" John nodded.

"Go get it. It's in the car…Oh, my god. Gunshots, punctures, burns, some broken bones. Second-rate medical treatment if anything at all. Sarah…" Charley trailed off, as Sarah looked at him, obviously at a loss at what to say.

"I need more light" Charley stated, as Sarah passed a lamp over, as Derek seemed to slip out of consciousness.

"Stay with me, okay? Derek?" Kat queried, as his eyes fluttered shut, but his grip on her hand remained strong.

"How are you doing?" Charley inquired.

After an hour she had managed to get her hand free from Derek's surprisingly strong grip, and was slowly watching as his blood washed off her hands. However, no matter how much she scrubbed she felt like she could still see the red substance.

"Shouldn't I be asking you that? Did Sarah explain everything to you?" Kat suggested, turning around and drying off her hands.

"Machines…the end of the world…people from the future…" Charley mumbled, still not having taken it all in.

"Maybe you should sit down" Kat laughed, as they walked into the other room.

"And you've known about all this since you were a kid?" Charley asked, as they sat down at the table.

"That's a lot for one kid to take on" Charley stated.

"I survived" She shrugged, as she spotted Cameron walking into the kitchen with a pillow in hand.

"What are you doing?" Kat questioned, as she saw Cameron hovering over Derek, a pillow in her hands.

In response, she carefully moved his head and placed a pillow underneath, and looked back up at her in confusion.

"Did you do something to him? In the future?" Kat asked.

"I don't know" Cameron replied.

"How can you not know? Because he certainly seems to remember you" Kat accused.

"When they reprogram us, they scrub our memories. It increases the chance of success" Cameron explained.

"Oh…" Kat trailed off, realising how hostile she had been.

"Have I done something to upset you?" Cameron queried.

"No, why do you ask?" Kat frowned.

"Ever since Derek Reese has arrived you've seemed hostile towards me" Cameron answered.

"He just made me realise that…you're not human. You're a machine" She confessed.

"You had forgotten that?" Cameron inquired, confused.

Before Kat could reply, Derek suddenly began coughing up blood, as she sprang into action and pulled him onto his side.

"His lungs are haemorrhaging. He's drowning in his own blood" Cameron advised, as Kat's eyes widened in panic.

"Charley!" She screamed.

They managed to stop the bleeding but Derek had lost a lot of blood and wasn't going to make it without a transfusion. Cameron suggested just letting Derek die as he knew too much, which appalled Kat. Luckily, John asked to be tested to see if he was a match and thankfully he was. Kat gave Cameron a glare as she walked into the kitchen, and sat down besides John who was slowly transfusing his blood.

"Does it hurt much?" Kat asked.

"Only when I breathe" John gave her a pained laugh.

"It must be so weird…suddenly having an uncle" Kat stated.

"I just keep thinking, is this what my dad looked like? Is this how he acted?" John admitted.

"Maybe you can ask him that when he's better" Kat smiled at him.

"If he lives" John sighed.

"I don't understand why my dad never mentioned that you had an uncle…I mean surely he would have met him in the future" Kat exclaimed.

When Kat's adoptive father had first told her that he was a soldier from the future, she had thought he was insane and had tried to run away from him. However, after she had seen the machines first hand she quickly realised that he was telling the truth. She still wished he had just be lying.

"Maybe he just didn't mention it because he never thought you would meet him" John suggested.

"I wish he had told me…" Kat trailed off.

"What's wrong?" John queried.

"I don't like this. The unknown. I've always known one thing…protect you and Sarah. And now this guy shows up…am I supposed to protect him like I would you?" Kat pondered.

"Kat, don't talk like that" John sighed.

"Like what?" Kat questioned.

"Like protecting us is all there is to you" John replied.

Before she could answer Derek suddenly woke up and began shouting for his brother, surprising them both.

"Where's Kyle? Where's Kyle? Where is he? Where'd you send him?" Derek repeated, as he grabbed onto John's shirt.

"Woah, woah. Stop, its okay. Let him go" Kat said, as she managed to wrangle his grip off John.

Charley and Sarah had rushed into the room and were trying to restrain Derek, but he was strong even in his weakened state.

"No, uh-uh, no. Get off me! Where is he? Where'd you send him? You owe me the truth!" Derek shouted at John, who backed away, with tears in his eyes.

"Get this off! Get it off of me! Get- He's my blood. He's my blood! He's my blood!" Derek cried, as he slowly stilled, seeming to have worn himself out.

"Derek…hey, look at me. You're confused, alright? The years 2007. You're with Sarah and John Connor. You got sent back, remember?" Kat told him, as he looked at her with unfocused eyes.

"John…where…where's Kyle?" Derek stuttered, his thoughts a mess.

"He…he got sent back too, remember?" Kat went on.

"John sent him back…and me. I…where…where am I?" Derek asked, blinking hard.

Kat watched from across the room as later that evening, John sat down next to Derek and told him the fate of his brother. She watched Derek's expression changed from prideful to sad and then back again. She could tell John so badly wanted to tell him that he was his uncle, but with Sarah looming behind him, he couldn't. Kat was glad he had lived, she had so much to ask him, but she knew he would need rest. She saw Cameron standing not far behind her and frowned, wondering what the machine was thinking.

Author's Notes: I hope you all enjoyed this chapter! I think it's going to be really interesting seeing Kat's relationship develop with Derek, and find out more about her past. Please leave a review if you want me to continue writing this story:)

olischulu: I'm glad you think my OC is well integrated, as I feel like that's really important. Season 1's plot is going to stay quite similar, but Season 2 will be going down a much more AU route as Kat's going to change the storyline quite a bit. Thanks for the review:)
