Sorry it took me a bit to get this posted, guys. It kind of didn't make any sense at all the way I wrote this thing at first, and it's not like it makes thaaaat much sense now, but I'm hoping that starfleet's superior medical knowledge will cover for me. =D)

After three hours, Danni had found nothing in the way of a cure. Both she and Harry were anxious to get back to caring for the patients, but they both knew that the research to heal them was more important. Harry sat still, twisting his fingers, as Danni started yet another test on him. At last she set the tricorder down with a sigh.

"I can't find anything," she admitted. "You have a normal number of red blood cells, no unusual brain activity, no stimulants in your blood… You haven't got anything that I can imagine would cause you to be immune to this disease." She closed the tricorder. "Did you have any unusual diseases as a child?"

"I had… Jensky's Ague, but that's nothing unusual," Harry said, shrugging his shoulders. "Most of the crew has had that at one time or another. I've had plenty of colds, but I was vaccinated for 'most everything else," He said, trying to think. He concentrated hard and then- "wait!" He said excitedly. "Wait, I did have something strange. I remember my mother telling me about it. I caught the chicken pox when I was about three years old."

"Chicken pox?" Danni's brow wrinkled. "But that has been nonexistent for nearly 200 years!"

"I know," Harry replied. "At least, that's what they thought. But I caught it. It was relatively easy to treat, and my mother told me that I was completely well within three days."

"Harry!" Danni exclaimed. "Maybe your antibodies and white blood cells have some sort of immunity to this disease. Maybe the information about the chicken pox in your immune system has enabled it to keep this disease out."

"That would be a one in a million chance, Danni," Harry pointed out. "And besides, what are you going to do, replicated my white bloods cells and antibodies?"

"Exactly," Danni nodded determinedly. "There's no guarantee that this'll work, I know. But if you're the only person on this ship to have had chicken pox, which it's a sure bet that you are, then maybe your immune system is able to keep this disease out because of that."

"That's odd," Harry said, shrugging. "But it's a start."

Danni gathered white blood cells and antibodies from Harry's bloodstream with the injector set to reverse. Taking it over to the replicator, she commanded the system to make her a replica of the contents of the injector. It half-heartedly made an effort to replicate the contents, but fizzed out, retracting the nearly-formed vial.

"Great!" Danni shouted, stopping herself from slamming a fist into the replicator.

Harry clenched his jaw. "We're going to have to take this one step at a time. I'll shut the console in the doctor's office down for a moment, and then you'll have to replicate my blood cells and antibodies fast. We can restart the console in a few moments."

"But you might not be able to start it again," Danni said, twisting a strand of her hair behind her ear. "If you shut down the system, it might be hard to get it running again."

"I know, but if the console is drawing too much power for the replicator to start up, then you might have trouble replicating your antibodies and white blood cells."

Danni sighed. "All right, but if it takes me too long, we'll have to terminate it and try again. I don't want that console shut down for more then five minutes."

"It shouldn't take the replicator that long to replicate it," Harry reasoned.

"All right then, hurry up and shut it down," Danni said, sending Harry skittering to the office to reset the console. A few moments later, the replicator hummed softly, restarting. "One vial of the contents of this injector."

The replicator hummed for a moment, inspecting the contents of the injector. Then a small vial formed. Danni reached out with a trembling hand and grabbed it. "You did it," she said softly.

"You did it," Harry said. "I only got the replicator working."

"We both did it," Danni argued. "Now, who are we going to test this on?"

Harry stared at her, not comprehending her words for a moment. Then he groaned. "Oh no, not another big decision."

"Who will we test it out on?" Danni repeated. "If anyone were in their right mind, I'd ask them, but I don't think anyone is."

"Test it on me," a halting voice insisted. "You can test it on me."

Danni and Harry both turned to see Chakotay propping himself up on his elbow, obviously barely able to keep himself upright.

"But, commander!" Harry seemed at a loss for words.

"Look, you've got have someone-" Chakotay slumped back down on the bed, his arm no longer supporting him.

Danni bent over him, grabbing one of his hands. "But you're our first officer, we couldn't do without you."

"I can think of quite a few people on this ship who would be happy to do without me," Chakotay informed her.

"I couldn't do without you," Danni said stubbornly.

"Yes, you could," Chakotay told her. "You did without me when I joined the Maquis."

"That was years ago," Danni said. "And I knew I could choose at any moment to rejoin you."

"Danni, you need someone to test the serum out on, and I'm volunteering," Chakotay said. "If you don't test it, we're going to die anyway, either from the sickness or from life support failure."

Tears pooled in Danni's eyes, but she nodded to Harry to put some of the serum in the injector. Harry did as she wished, and handed it to her. Danni squeezed Chakotay's hand, bit her lip, and injected the virus into his neck. Chakotay settled back onto his pillow while Danni stared. Chakotay slipped back into unconsciousness and still Danni watched his face.

"Danni, you can't expect it to work right away," Harry said. "Go lay down again, and I'll watch out for him. If there's any change, good or bad, I'll let you know."

Danni didn't respond, but returned to the corner with the quilt and pulled it up over her head. Had she not been so fatigued, she would never have been able to fall asleep.

"I think I'm in love." -- Tom Paris

Danni awoke in much the same scenario as the last time, with Harry's excited face over her. But this time he was laughing and crying and had lifted her shoulders half up off of the ground. She tried to push him away, to get him to calm down so that he could tell her what the verdict was, but he couldn't speak.

"Harry, what is it?" She asked. "Is Chakotay-"

"He's well! He's well! It only took an hour for the serum to start working on his bloodstream, and after another two hours, he's completely well! He's a little weak, but I replicated some soup to feed him and he's wanting more."

Danni grabbed Harry's shoulders then, her face lighting up with pure joy, "Harry, we're going to live, we're gonna get out of here!" She leaped up, rolled the quilt up and handed it to Harry. Harry set it down and followed her to Chakotay's bed.

"Hi," Danni said, touching the tattooed forehead. "You're looking better."

Chakotay only smiled for a minute. "I've been feeling better," he said slowly.

"You don't say," Danni replied, feeling as though her heart would burst. She hugged the first officer and turned back to flash a grin at Harry.

"What are you waiting for?" She asked, putting her hands on her hips. "Get more injectors filled with samples of that serum!"

"Yes ma'am!" Harry said, feeling rejuvenated for the first time in days.

"You should start with B'Elanna," Danni suggested. "We'll need her to get the warp core reactivated."

"I'm on it," Harry replied. "And don't worry anymore, we found it!"

"Yes, we, Harry, and I can't think of a better person to be celebrating with right now."
