Excuse for sending the wrong chapter, I hope I'm not become confused.
So now with the correct chapter.

Chapter 11

For a while, Steve sits there and tells Danny what they will do when Grace is back, before his phone rings. Without looking at the caller ID, Steve answers it.
"McGarrett."
"Morning, Boss. It's Kono. We've got a hot trail concerning our Dr Cold. I spoke to his brother yesterday. While he hasn't seen or spoken to him in a long time, the last time they spoke, Ted told him that he'd received a job offer in Hawaii."
"Then he's here on the island? But you said there was no record after he was dismissed!" Steve is struggling to follow Kono.
"That's right. I went through the whole thing and I found him. He arrived six months ago under the name Norman Smith. He's using this alias to rent a farm outside the city, a multi-building one with a small lab set up where he wouldn't be disturbed. Like I said, he has a job as in IPM, as production manager in the Department of Vaccines," Kono explains. "Chin's just spoken to the lead representative and sent him the photo. He confirmed its Dr Cold. He couldn't believe Dr Cold could have done something like this; according to him, Cold is always punctual and reliable. Apparently, he's volunteered to take the night shift for the last three weeks."
"So he could have made the vaccine there."
"Exactly, because he could work during the nights in peace, since there's no-one else there. He was working last night, so he should be at home. Chin and I are going with HPD to arrest him."
"If you come and stay with Danny, I'll go over there," Steve suggests.
"We've already got Duke and his team coming with us. You stay with Danny, Boss; he needs you more."
"Okay. Be careful."
"Of course!"
With that, they end the conversation and Steve leans back in the too hard chair.

A while later, Dr Carter comes back into the room and checks all the monitors, as well as all the connections.
"Everything looks good," she begins, before stopping.
"But?" Steve asks, hearing something strange in her voice.
"The last urinalysis showed that his kidneys are being overstrained. We'll try and use LD12 to help his kidneys filter his blood. But it does not degrade the organism itself."
"Can you be honest with me?" Steve asks. "What's next?"
"We'll try and relieve the strain on his kidneys, as it would have serious consequences if they failed," she explains.
Before Steve can say anything, a nurse comes into the room. "Dr Carter, Dr Yakani sent me. Patient McNeill has started to move. Please, come with me."
"What does that mean?" Steve asks in amazement, looking at the doctor, already at the door.
She turns her head to him. "We'll talk later; I have to go." She then left the room, leaving a confused Steve behind, unsure of what to make of this new revelation.

After another two hours, Chin and Kono arrive at the hospital.
"Do you have Dr Cold?" Steve asks them, hoping for a positive answer.
"Yes, but there is a problem," Kono replies, uncertain of how their boss will react.
"What is it?"
"There was an explosion," Chin says shortly.
"Was anyone injured? Are you guys okay?" Steve asks worriedly, looking at their forlorn faces, as if they were somehow responsible for the accident.
"We'd just arrived when there was an explosion in the basement. None of us were injured, but Dr Cold didn't survive. Plus, the whole lab is a mess, and all records there have been destroyed too. CSU are still trying to find something, but Charlie isn't hopeful that he'll find something on the computer."
"Dammit! That was our last chance!" Steve slams his right fist into his left hand in frustration.
"And now? How's Danny?" Chin noticed the deep worry lines on McGarrett's forehead.
"His kidneys are causing a lot of worry. It looks bad, unless something happens soon," Steve admits.
"No, I can't believe that. You're telling me that we should give up on him? That there's nothing that can resolve this stupid paralysis." Kono storms over to the window and stares outside at a little park in front of the hospital.
"Kono, please. What can we do? Even Dr Carter doesn't know what to do, and she created this," Steve explains, trying to remain quiet.
"Hey, do you have to do this here? Danny can still hear us," Chin interjects.
"You're right. It's just that I don't want to believe that it's too late," Kono dejectedly replies, looking towards the floor.
"I'm going to speak with Danny's doctor again. Can you stay here with him?" Steve asks his colleagues and stands up.

After Steve leaves, Chin sits in the now-free seat and starts talking to Danny encouragingly.

Steve slowly walks along the hallway until he reaches Dr Yakani's office. Before he knocks, McGarrett takes another deep breath and tries to sort through his thoughts.
"Enter!" calls a female voice.
Steve sticks his head through the door and sees Dr Carter is deep in files.
"Dr Carter, I wanted to speak with you again."
"Take a seat, please, Commander! I wanted to speak with you as well. As soon as I had checked something out, I was going to find you."
"What did the nurse mean? McNeill can move again? Is he another patient?"
"Yes, he came yesterday morning with the same symptoms. During the night, he slipped into the fourth stage. That's when the patients can no longer open their eyes," she fills him in, after a sigh. "In contrast to the others, this patient had developed an infection in the original injury. His fever rose to 107.5˚F, and a few hours ago, he started to move his fingers. Shortly before you came, I got the news that he's now able to open his eyes."
"How so?" Astonished at the news, Steve looks expectantly at the doctor.
"I would have come out much sooner. But I have assumed that it is much more effective at higher temperatures."
"What do you mean?" Impatiently, Steve slides his chair forward.
"The instability of LD12, in terms of heat. That means that, above temperatures of above 110˚F, it slowly loses effect," Dr Carter patiently tells him, although she would like to study the files some more.
"What does that mean for the other patients?" Steve presses.
"We have already started with a so-called whole-body hyperthermia therapy. It goes like this. The patient will lie in a special bed, where a UV lamp will increase their core body temperature. The next few hours will show if it works well or not."
"Why can't we do that with Danny?" Steve demands.
"107˚F, or even 108˚F, is in itself critical, but with his failing kidneys, this is extremely dangerous."
"What do you mean?" Unsure of what the scientist is getting at, Steve looks at her.
"Dr Yakani isn't sure whether we should risk it. A high temperature means a higher demand for fluids, which would overload Danny's kidneys."
"How long would you have to maintain his temperature at a high rate?"
"With McNeill, eight hours was enough before an improvement was seen. However, I have to mention that he was in a much lower stage than Danny. In his case, I would recommend a period of 24 to 32 hours to be sure. This would, however, be an enormous burden."
"What is your honest opinion?"
"I think that we don't have any other options. We have to do something soon, or his internal organs will start to shut down. It has to be said, of course, that there is a huge risk."
"Why must his temperature be kept up for so long?"
"The length is only estimated on the basis of the fact that the substance has already been in his system for over 24 hours, as well as the fact that his temperature will be increased artificially."
"How high is probability that there won't be any permanent damage or consequences from this?" Steve is worried about the possible outcomes of this treatment.
"Thirty to forty percent."
Just like when he was in the SEALs, Steve quickly goes through every scenario to reach a decision. Leaving Danny himself is not an option. The possibility of seizures and brain damage is not much better. The doctor watches him intently as he comes up with an answer. You can easily understand it is for Steve to make a judgement on this.
Steve raises his head and takes a deep breath before he answers. "I think we have no other choices. Danny will make it." He hopes he has made the right decision.
"They want us to raise his temperature. You are aware of the risks, aren't you?" Dr Carter reiterates.
"Yes, Doc, I am!"
"Then I'll take care of everything and inform Dr Yakani. I will see you later."
