A word to the reader, before I begin... This isn't going to be my usual style of 'happy' story, but since you asked for back story on Kim's husband and their relationship, here it is.
The persistent ringing of the bannana was driving her nuts. In her head, she knew Bannana's weren't supposed to ring. The voice was familiar as well. "Kim... Kim... I hate to do this..."
The icy blast of air sent Kim bolt upright, then down again, tugging the blankets up against her neck. "Alright Wade, I'm up. Give me one second." she snatched a jacket from the floor of her bedroom, and then grabbed the Kimmunicator as she slipped it on. "Go ahead."
"Sorry to wake you, but you have an emergency call incoming. I've already got a ride on the way." Wade smiled. Monique had succeeded in drawing him out of his room, so he was now sitting at a table. She'd not been able to sever his computer from him, nor had she had the heart to try, so he often was seen with both.
"Are Ron and Shego getting up?" Kim asked. Wade shook his head.
"No, the call wasn't for Team Possible, but for you. It's from Joseph Whitehawk." Kim nearly dropped the com device. "Are you alright?"
"Uh yeah, it's just... nevermind. What's the sitch?" she asked, still shaken.
"He didn't say, just that they needed help, and right now." Wade stared for a moment. "I can look into it more deeply for you."
"No, that's alright, I'll go. My ride?"
"Landing on your roof.." Kim changed in rapid fire mode, and was up the stairs of the apartment building she was living in not five minutes after Wade told her the ride was arriving. She got there just as the jump jet did. The building was full of GJ agents, so it wasn't counted as odd having an aircraft land on the helipad on the roof. She climbed in, strapped down, and gave the pilot the thumbs up. He nodded, carresed the throttles, and took off. Kim had taken a job with Global Justice just a few months out of high school, working with their trainers, going to college, and saving the world, the last free of charge. She had been bumped to field status shortly after graduating with a degree in criminology. It was this that had led her to be on the reservation all those months ago, when she met David Whitehawk, a Tribal Policeman, and helped him with a poacher problem. He was the sort of person you just couldn't help but like. Kim liked him at first sight, but it wasn't until he asked her for coffee that she'd discovered his feelings on the matter. She'd been to visit him twice, and each time she'd felt herself growing a little closer to him. The attraction was obviously mutual, though she found that like Ron he had some trouble putting words to his thoughts. It took no more than an hour for the jump jet to reach the destination, though it had to refuel partway. The powerful engines kicked up dust as it touched down outside the main office of the reservations Tribal Police. Kim thanked the pilot, and jumped out, jogging easily to the door, as the plane lifted away. She entered the door after the dust had settled, and apologized for the dust.
"Kim?" a grey haired man stepped out from an office in the back. He was only a little older than last time she had seen him, but Joseph Whitehawk's hair was completely white now. He smiled weakly. "C'mon into the back. I know you're wondering what's going on, so I'll tell you." She entered the room, and he followed, closing the door behind himself.
"Is David alright?" she asked in almost shreds.
"He's fine. Or as best he can be. Let me explain. David told you about Lee, right?" Kim nodded, and he continued. "Well, Lee isn't in a complete vegetative state any more. The unfortunate problem, is that his other side is taking over." Kim swallowed, knowing what was coming, but not wanting to believe it. "He calls himself Sam, and he killed two nurses, and a group of guards on his way out of the hospital. David had just left him, and was optimistic about his chances. After that, he's gone completely sour. I need your help. I have to find Sam, and I have to keep David away from him. I'm afraid if he finds him, and it's Sam, he'll kill him."
"What can I do?" Kim asked.
"I can't in good conscience send you after Sam, so I need you to try and talk David out of this depression he's in." Joseph sighed, and slumped into his chair. "Lyn has been arguing with him for the past couple of days, trying to keep him from going after Sam. She's completely tired."
"Don't worry, I'll do what I can. Do you want some technical help hunting for... Sam?" Joe smiled back at her.
"That would be helpful." he nodded. "We aren't exactly high on the budget lists." after setting them up with Wade, Kim stepped out into the desert sun, and started the walk to David's house, a little ways down the road from his parents house. She arrived to see his mother stalking into the room. Kim reached for the door handle, to find it yanked away, as David opened it from the inside. She looked into his eyes, then was forced to look away, even if only to the bridge of his nose.
"Kim..." he whispered her name hoarsely, and she caught him as he collapsed forwards, sobbing. She stood steady, letting him go. His mother, a woman who appeared on her last legs at the moment sighed in relief at the sight of Kim. Kim waved her off, and she nodded, slipping out and heading home, hopefully for a nap, was Kim's thought. After a few minutes, David's sobbing decreased, and started to slow. He lifted his weight off, and she led him to the couch. He sat down, and looked at her again. His eyes were not as painful this time. He wasn't cured by any stretch, but he was pushing the pain back. She smiled, and his eyes seemed to dance for a moment. She could tell he was now relaxing, if only slightly. "I'm sorry, I didn't mean to drop on you like that. Are you alright?"
"I'm fine, I practice dragging firefighters in full gear around, so you're a light weight." she laughed, and play-punched his arm. He smiled, but didn't laugh. She just caught a shudder.
"Father told you. That's why you're here." he said. It wasn't a question, but instead a simple statement of fact. "I'm sorry he dragged you into this."
"I wasn't dragged into anything. If I didn't want, need to be here, I could have left. I didn't." She pressed her hand to the side of his face. "I want to be with you now. There's no where else I could be." He smiled again, with a little more enthusiasim. "Now, perhaps we should get down to business. Your father asked me to keep you away from Lee."
"No, not Lee, Sam. I can't believe that this man is my brother or I'll hesitate." David's eyes narrowed.
"Stop that. There might be a chance to save him, but if you just start shooting, we'll have a problem." Kim answered, reaching for her Kimmunicator.
"Look I can't..." She glared at him, staring into his eyes. "I don't want you involved. You might get hurt."
She slapped him. It wasn't hard, but it was enough to cause him to stare at her. "You hit me."
"Because you're treating me like a child. I'm more than capable of taking care of myself, I don't need you to do it for me. Now are you going to listen?" He nodded, rubbing his cheek. She kissed the other one, and then picked up the Kimmunicator. "Wade, you there?"
"Usually. What can I do for you?" Wade answered. Kim stared for a moment before answering. Either he was usuing his holographic generator, or he was at the mall.
"Simple enough. I need to research a way to restore David's brother." Kim answered. The screen exploded in a close up look at a diet coke.
"Are you sure you don't want a talking spaceship to fly you to the moon?" Wade answered. "I'll take a look,but I can not promise anything. I'll get back to you." The line cut out. Kim raised an eyebrow, but shook her head.
