A/N: In this chapter I utilize some scientific jargon and explanations for the characteristics of the virus in order to make it seem more realistic. I realize that not everyone is a biologist so I will try my best to explain everything in laymen's terms. That being said, if you have any questions please PM me or put it in a review and I will do my best to respond and/or address it in the next chapter. For those who are scientists, please understand that there is a science fiction aspect to this. Not everything will be 100% accurate and it's rather simplified overall. That being said I hope you enjoy this chapter. Please follow, favorite, and review.

Day 02: Puzzles of Epidemiology

The morning sun shined through the windows of Capsule Corp, illuminating the guest bedroom occupied by the husband and wife pair. With the light hitting her face, Chi-Chi yawned as she slowly woke up, turned around, and gazed at the beautiful sunrise. It was a perfect, picturesque scene before her; the clear sky giving way to the sun as it brought light to the sprawling city…

"Wait!" She jumped up. "City?" And then she remembered where she was and what had occurred the day before – reality set back in. The last thing she remembered was watching over Gohan, with Goku by her side.

"I must have fallen asleep." She thought. "But how did I get in this room?" She looked down at Goku who was snoring softly beside her. "He must have brought me here." Chi-Chi had to admit that she got a rather good nights rest despite the chaos of yesterday. However, the danger wasn't over. Leaping out of bed, she quickly made her way down the halls in order to be back by her son's side.

Bulma took a sip from her coffee as she looked over the papers her father had just handed her. "Hmmm…" She contemplated aloud as she read and processed the information. "This is good. We are getting somewhere with this." After continuing to flip through the report her expression grew puzzled. "But it is strange how this virus is acting."

"I know. It's so familiar yet, at the same time, I've never seen anything like it." Dr. Briefs replied as he continued to enter data into the computer.

Bulma took another sip from her cup, emptying its contents. "Darn, out already. Well I could use some time to stretch my legs. Do you want me to get you some more coffee as well?"

"Yes, thank you."

The blue-haired woman smiled. In his response, her father hadn't even looked back at her. He was so preoccupied with figuring out this illness that he had become totally entrenched in his work. "Such is the life of a scientist." She thought to herself as she made her way out of the lab.

She had not traveled far down the hall when she ran into her old friend. "Chi-Chi, you're up already?"

"How's Gohan doing?" Chi-Chi asked, almost in a panic.

"His health status hasn't changed since last night. But we've found some more information about the virus that might help us in combating it."

"What? What did you find?"

"It's rather technical. Why don't we talk about it over breakfast?" Bulma tried to lead her friend in the direction towards the kitchen but Chi-Chi backed away.

"No, I want to be with Gohan."

"Chi-Chi, you need to eat. You haven't had anything since you've been here." Bulma responded sympathetically.

Adamant in her choice, Chi-Chi shook her head in refusal. "I don't care, I want to see him."

Bulma sighed. "How about we compromise. We'll drop by Gohan's room to see him but then you have to come with me to get some food."

Her friend remained silent as she thought hard about the offer.

"He's being well taken care of. Right now the best way you can help him is by getting your strength back up and answering some questions about what happened when Goku had the virus. We're trying to look at every little detail in order to gain more information about it so we can successfully fight it and prevent further infection."

Chi-Chi took a moment to think before finally nodding in agreement.

The two women made their way to the infirmary where they saw Dende just as they left him; standing over Gohan, emitting a healing aura.

"He has to be so tired." Chi-Chi commented.

"Namekians are used to going long periods of time without sleep." Piccolo remarked. His eyes remained closed as he stood in the same position he had been in since when he first got there. "That being said, he's had to take a few breaks throughout the night. I'm sure you're aware that he won't be able to keep this up for too many more days."

"I know. I'm already working on a plan." Bulma replied.

"You are?" Chi-Chi asked.

"Yes, but I will only tell you while we eat." Bulma motioned for them to continue on.

Chi-Chi pressed her hand against the window in the door, taking one last look at her son. She felt so powerless. The only thing keeping her going was trust in the care being provided to him. "OK." She said turning toward away. "Let's go."

The pair made their way to the kitchen where Bulma motioned for Chi-Chi to sit down at a table while she prepared some food. With her modern appliances all she had to do was punch in a few numbers into an apparatus and wait for a hot meal to be prepared. By the time she poured both of them some coffee, everything was done and she was serving up a much-needed breakfast. "Here you go." She laid the plate in front of Chi-Chi while sitting on the opposite side of her.

Hesitantly, Chi-Chi took a small bite. She felt guilty for not being near her son but she knew she would never hear the end of it if she continued not to eat. Of course, as soon as she took her first bite she realized how hungry she was and began to scarf down her meal.

"Ah Chi-Chi, you need to slow down there." Goku commented as he entered the kitchen.

Knowing he was going to be in need of some nourishment as well, Bulma stood right back up. "Have a seat Goku, I'll get you something to eat."

The Saiyan sat next to his wife while Bulma repeated her previous action of getting coffee and instantly preparing a meal. In no time she was joining her friends back at the table. "I'm actually glad you're up Goku." She said handing him his food and seating herself again. "We've been able to find out a little bit more about the virus."

"Do you know how to cure it?" Chi-Chi asked.

Bulma shook her head. "Unfortunately, no. Not yet at least. The good news, however, is that my dad was able to extract a residual amount of the medicine from the vial you had. That sample is currently being run through a gamut of tests in order to figure out what it's made of so we can recreate it."

"So it was helpful?" Goku inquired. He wanted to make sure he understood everything correctly.

"Yes, very helpful." Bulma confirmed. "The blood samples everyone provided have also been a tremendous help in figuring out more about the virus. So far we've learned that it's what's called an adenovirus. Usually these types of viruses just cause mild symptoms like the cold or the flu. Occasionally they can lead to myocarditis, or inflammation of the heart, but it's rare. It's even more rare for them to be deadly, which makes this specific virus species extremely unusual. Also, adenoviruses normally don't survive long outside of a host but are transmitted easily from person to person. In this case, however, the opposite seems true. We're still running some tests but the fact that nobody has gotten sick from this except for Gohan, weeks after Goku had it, provides evidence for this conclusion. While this information creates some problems in tracking down how Gohan received it, it helps us to understand how it interacts with the environment. On another positive note, we found no presence of the virus in either of your blood samples. This adds to my theory that it's not easily transmissible. The only downside is that we were unable to learn anything about the medicine from either of your blood samples. It was something that has already fully passed through your system."

In hearing this, Goku and Chi-Chi understood they had to take the good with the bad. They also knew that, in the very least, Dr. Briefs was able to utilize the vial of medicine they had saved.

"There is a perplexing aspect to all of this." Bulma sat back thinking aloud.

"Huh? What do you mean?" Asked Chi-Chi.

"Well, when we took a sample of Gohan's blood yesterday we were able to identify the virus under a high powered microscope. Yet this morning, looking at the same blood sample, we can't find any trace of it."

"What does that mean?" Goku questioned.

"I don't know. My dad should be drawing more blood as we speak so that we can see what is happening to virus in Gohan's body. Additionally, we will have some more tests prepared today to help understand how it interacts with the heart. In the mean time I wanted to ask you both a few questions. Had Gohan displayed any symptoms prior to yesterday?"

"No, he's seemed perfectly healthy." Chi-Chi answered.

"And when he fought Cell he was at the top of his form. Based on my experience, if he had the heart virus he wouldn't have been able to fight." Goku added.

"Hmmm…" Bulma thought aloud once again. "Goku, when you had the virus the others mentioned that it seemed to hit you pretty fast. Is this correct?"

He took a second to think. "I-I guess so. It wasn't too long into my fight with the androids that I began to feel pain in my chest."

"And they also mentioned that it seemed to quickly escalate when you transformed into a Super Saiyan."

Goku nodded in response.

"So based on those facts I agree with you Goku. I don't think Gohan was infected with the virus during his fight with Cell; otherwise the physical activity and his transformations would have triggered a response. He must have gotten it within this past week. Tell me has he trained or transformed into a Super Saiyan since the fight?"

"No, he's mostly been in his room studying." Chi-Chi quickly responded.

Goku agreed. "He's actually been taking it rather easy. The only real physical activity he's done was when we flew to the river and went fishing."

"Hmm, that provides a bigger time table of when he could have gotten the virus since it seems to be triggered by physical activity. At least we can be pretty certain that he got infected some time after the fight but before yesterday." Bulma sipped her new cup of coffee trying to think of what she wanted to ask next but before she could continue Dr. Briefs came bursting into the room. "Bulma! You're going to want to see this!"

Without hesitation she jumped up and quickly followed her father back to the lab with Goku and Chi-Chi close behind her.

Inside the lab Dr. Briefs had hooked up monitor to the microscope he had been working with. "I figured out why the sample of Gohan's blood that we took yesterday had no trace of the virus this morning. Look at this image."

Bulma focused her attention on the monitor. Displayed was a blood sample consisting of red blood cells, white blood cells, and small green dots.

Dr. Briefs continued. "Those green dots are markers indicating the virus. Now watch closely."

Everyone looked and as time passed some of the green dots began to vanish, followed by some more, and some more. "It's his white blood cells. They're destroying the virus at a rather rapid rate in comparison to what's normal." Bulma observed.

"Exactly!" Her father exclaimed. "This is a sample of blood I took from Gohan just after you left. When I first analyzed the blood it contained many more viruses than you see now. His immune system is destroying it at an incredible rate."

"This doesn't make any sense." Bulma was completely perplexed. "How come his immune system isn't taking care of it in his heart? How come Goku died from it in another timeline? Based on what we are seeing here, Gohan should no longer have it. In fact this virus shouldn't even exist!" Just when they were getting a better grasp on the virus, this happens.

"I've called West City Hospital and told them I needed their digital electo-magnetic resonance machine as soon as possible."

"Good thinking." Bulma replied. "We need to see what going on in his heart."

"It should be here in a few hours. In the mean time I have some more tests I'm going to run." Dr. Briefs hastily left for the adjacent laboratory room.

With a mixture of confusion and anxiety Chi-Chi finally spoke up. "Bulma, what's going on? What does this mean? What's a digital e-electra…"

"Digital electro-magnetic resonance machine." Bulma cut her off while she started to pace. "It's a piece of medical equipment that only major hospitals have. With it we can essentially get an image of anything we want in the body, such as an organ like the heart, and even go down to extremely microscopic levels, all in real time. It's a highly sophisticated machine."

"OK, but what does all this mean?" Goku asked referring to the monitor they had just been look at.

Bulma stopped her pacing and tried her best to explain the biological implications of the recent findings. "Well, as you just heard us say, Gohan's immune system is attacking the virus at a rapid rate. It explains why we couldn't find a trace of the virus this morning in the blood sample we took from him yesterday. His white blood cells had destroyed them all. There are a few things about this that don't make any sense to us yet. The first is if Gohan's immune system is destroying the virus this fast in his blood then why hasn't it gotten rid of the virus in his heart? Of course we know this virus is deadly, but based on this new information that fact doesn't make any sense. That's why we are getting the machine my dad talked about - so we can get a better picture of how the virus is interacting with his heart. Second, a virus like this shouldn't exist in the first place. From an evolutionary perspective it doesn't make any sense. For one thing, it only attacked Goku in future timeline and nobody else. In this timeline it's affected Gohan as well, but nobody otherwise. We believe it can live outside the body for a very long time, which is a nice adaptation, but a virus this susceptible to the immune system is at a great disadvantage. Additionally, it doesn't seem to be easily transmissible, otherwise Gohan would have gotten it much earlier and Future Gohan would also have gotten it. In nature this thing should have easily died out. It's like we're missing a big piece of the puzzle here."

"What can we do?" Goku asked with a strain in his voice. Bulma realized she had inadvertently caused more worry to her friends.

"Let's go back to the kitchen. Maybe we can narrow down when Gohan got the virus."

"Hmph." Vegeta scoffed as he fiddled around with the contents of the pantry. Despite living on Earth for several years now, he still had no idea what half of the food items were. "Damnit! Is there nothing here?" He slammed the pantry door, making its top hinge break off.

"VEGETA!" Bulma yelled from nearby.

"WHAT?!" He snapped back.

"You can't go around breaking things!" She entered the kitchen with Goku and Chi-Chi behind her.

Noticing his old rival, Vegeta shifted his focus away from food. "Kakkarot! What are you doing here?"

Rubbing her temple out of frustration, Bulma responded for him. "Vegeta, I told you yesterday after you came home late. Gohan is sick with the heart virus. We're taking care of him here while we try to figure out a cure. It's what I've been doing all day yesterday and today."

"What?" Vegeta's tone changed. He had been so exhausted the previous night that everything said to him went in one ear and out the other. "The same ailment you had?"

Goku nodded.

"Why didn't you give him some of the medicine Trunks left you?"

"There's nothing left. We're all out." Goku replied.

Rather than try and reeducate him on everything, Bulma changed the subject. "Where's Trunks?"

Vegeta scoffed once again. "Now who's forgetting things? He went back to the future. You were there."

Bulma's headache grew. "Not that Trunks. Our Trunks. The baby."

"O-Oh…" Vegeta stammered. "He's with you're mother."

"Can you tell her to continue watching after him? This thing is more complicated than we first thought. I may have to sleep down here again tonight."

"Fine." He muttered as he started to walk away. But before leaving he took another look at Goku. Behind his rival's pensive expression he could sense the fear felt over his sick son. Likewise, Goku could read past Vegeta's scowl and tell that there was some trace of empathy regarding the situation.

The Saiyan Prince left. While it's true he felt sorry for what was happening he also felt incredibly uneasy. Would the virus spread?

In order to make use of the time until the machine was delivered, Bulma continued to question Goku and Chi-Chi about the previous week. Unfortunately, despite the pages of notes she was taking, nothing helped to indicate when and how Gohan got the disease. At some point during the interview Krillin and Yamcha had woken up, making their way to the kitchen where they found their friends. After offering moral support to the family, and getting caught up on everything that had happened, Bulma decided to question them about the day Goku became ill with the virus. But there was very little they could tell her that she didn't already know. Still, it was possible that her notes might come in handy in the future. Just as she finished her questioning, Dr. Briefs came into the room. "Bulma, it's arrived!"

"OK, I'll be right there." She responded, getting up from her seat. Dr. Briefs dashed back down the hall to prepare everything for the tests that needed to be run.

"You can all wait in the large room just down this way." Bulma pointed.

"No, we want to join you." Chi-Chi argued.

"I'm not sure that's such a good idea. The tests that we are planning could potentially take all day."

But Chi-Chi insisted. "I don't care. I want to be with Gohan."

Goku looked at Bulma before facing his wife. "Chi-Chi, there is nothing we can do right now but let them work."

"B-But…" She started to protest.

"Gohan is being taken care of. And they can work faster without any distractions."

Torn between what she wanted and what made logical sense, Chi-Chi eventually took the advice of her husband.

"I'll update you as soon as I can." Bulma reassured her.

Chi-Chi sniffed back a tear and nodded in agreement. Bulma then followed in pursuit of her father.

The group made their way to a comfortable lounge area nearby where they were soon greeted by two Namekians.

"Dende, Piccolo." Krillin greeted with a wave.

"Krillin, Yamcha. How are you two?" Dende ran up to them in greetings.

"Doing OK. How has Gohan been? Are there any developments?" Krillin had still not even seen his sick young friend.

"No." Dende shook his head solemnly. "I've been able to stop any damage with my healing powers but I can't cure him of the virus. It continues to ail him."

Sensing the guilt that resonated within his friend, Krillin put a hand on the young Namekian's shoulder. "Hey, you've done well. Bulma and Dr. Briefs will be able to figure something out."

Dende smiled back up at him. Knowing Bulma, he was optimistic as well.

"So are you taking a break right now Dende? I've heard you've been working really hard." Yamcha asked.

"Oh, ugh, no. I mean I'm really not that tired, but Dr. Briefs didn't want me to continue my healing practice while they ran their tests. They said it could disrupt any data they might obtain. When I protested they assured me that I had already done more than enough and that when they were finished, I could continue."

Goku let out a smile. "I understand. You have done quite a bit Dende. We can't thank you enough for you're help. Let them work and you can get some rest in the mean time."

Dende smiled in return and agreed.

As dusk drew several hours later, Chi-Chi found herself pacing the floor. "What's taking so long?"

"Chi-Chi, they said it could be awhile. I'm sure they are working as fast as they can." Goku said trying to sooth her, but it wasn't helping. His wife continued to pace until she decided to take action.

"I'm going to see how much longer they are going to be." She stated as she took a few steps toward the hall.

"You're only going to distract them." Piccolo noted, stopping Chi-Chi in her tracks.

Spinning around, she glared at the Namekian. Before she could launch into a tirade on him Krillin intervened. "He's right Chi-Chi. We have to give Bulma and her dad some room here."

"But how much longer do I have to wait." She continued to fret.

"Just the time it takes you to walk from here to his room." A voice announced behind her.

Chi-Chi spun around again. "B-Bulma."

The blue-haired woman was wearing a surgical mask.

"Eh, what's with the mask Bulma?" Yamcha asked.

"We've learned a bit more about the virus, and even though it's probably not necessary, we're starting to take extra precautions." She handed everyone a mask. "Please put these on and follow me."

As they made their way down the hall Krillin questioned Bulma on the extra precautions she had mentioned. "Should we be worried?"

"The odds are you don't need this, but after what we found we just want to be extra safe. I will explain more inside." Bulma replied as they reached their destination. After she opened the door everyone stared in amazement at the new large piece of equipment that took up space in the center of the room. It looked similar to an MRI but a much more extravagant. Computers were mounted on each side and specialty lasers lined the inner parts of the machine. A complex series of lights and buttons tied everything together to make it look state-of-the-art.

Gohan lay in the center of the machine, green lights illuminating his body.

Chi-Chi gasped.

Perceptive to her friend's concern, Bulma reassured her. "Don't worry Chi-Chi it's completely non-invasive. Even if Gohan wasn't under sedation, he wouldn't have felt a thing."

She made her way to one of the computers where, displayed on the screen, was an outline of Gohan's body. His muscles and organs were pictured as semi-translucent masses. The only contrasting color was from various green dots throughout parts of his body with his beating heart glowing a bright green.

"I-Is that…?" Yamcha choked.

Bulma nodded. "The virus."

Using a file on the computer, Dr. Briefs placed a still image in the corner of the screen. "This is from an MRI we took yesterday. You can't faintly see some of the virus surrounding his heart." Focusing back on the real-time image generated by the new machine, Dr. Briefs continued. "This machine is supposed to give us a more detailed picture by essentially blowing up the size of the virus. As we can see here, some of the virus is carried into the rest of the body by the circulatory system. However, the majority, as expected, is located in the heart. Let me change some settings and zoom in." After a few seconds of typing, the lasers in the machine changed position and the light was now concentrated on Gohan's chest. A zoomed in picture of his heart was shown and the green dots became more distinguishable - as opposed to one giant glowing blob. "This gives us a better picture as to what's going on in the heart right now." Everyone remained fascinated, as they watched Gohan's heart beat in real-time.

Bulma mentioned the differences in the MRI image from yesterday to what they were seeing now. "Compared to yesterdays results, the virus seems to be growing at a rate slightly higher than expected. Dad, can you bring up the white blood cells so I can show them concentration in the heart?"

After a few key strokes a large amount of purple dots appeared. However, despite their number, they were dwarfed in comparison to the number of green dots. "What we see here explains why his immune system hasn't gotten rid of the virus." She pointed out the comparison to the group. "There are simply not enough white blood cells to combat the virus at the rate it's growing. Even when we first started several hours ago there was a noticeable difference."

Bulma turned to her father again. "Zoom in on an infected cell."

Adjusting a knob, Dr. Briefs zoomed the image onto a virus infecting a cell and pointed at the screen. "Now here we can see one of the viruses at work. This is attached to one of Gohan's heart cells. You see these long strands here? They are actually coming from the virus. What we've observed is that as soon as a virus latches on to a cell these strands extract itself from the virus and spread a great length over the surface of the cell. Normally, many viruses will attach to a single cell simply because it will be attracted to a protein on it's surface. However, in this case these strands prevent other viruses from attaching. They bump off and search for a cell that hasn't been infected. This helps explain why it's replicating so fast as well as why we can see a bit more than expected in Gohan's blood. Now let me zoom in even more." Dr. Briefs turned the knob taking the image to a molecular level. "As I mentioned the virus is attracted to a protein on the surface of the heart cell. This protein receptor, as we call it, is unique to the cells of the heart and is normally used in other interactions with the body. What's interesting about the protein receptor here, which the virus is attached to, is that it doesn't seem typical of what's recorded in the scientific literature."

Trying to absorb this information Goku finally raised a question everyone was thinking. "So, what does this all mean?"

"We can't quite say for sure yet. It's possible that Gohan has a rare type of protein. If he has it, a small portion of the population might have it as well, meaning anyone of you." Bulma answered. "This is why I asked you all to wear masks. What we discussed was that we would like to use this machine to look for this receptor in each of you. Krillin, you're closest to Gohan's height, which means we won't have to adjust as many settings. We would like you to go first."

"Oh, o-of course." Krillin agreed. He still didn't quite grasp everything that Bulma and her dad had said but whatever he could do to help Gohan, he would do it.

Bulma turned toward the rest of the group. "I'm sorry to ask this again, but would you all mind waiting outside? This will take some additional time." As she said this Dr. Briefs' assistants began to lift Gohan back onto his bed and sterilize the platform of the machine.

"Bulma, I'm sorry to bother you." Dende spoke up.

"Hmm?" She turned toward him.

"I was just wondering if I could I stay to continue healing Gohan?"

Bulma looked concerned. "Do you feel that you have strength Dende? We were going to give him some medicine which may help in slowing down the virus."

The small Namekian nodded vigorously. "Yes! I was able to regain all of my strength these past few hours. I want to do everything I can to help."

"Based on height he would also be the next one to be scanned." Dr. Briefs mentioned.

"OK." Bulma agreed. "But if you get too tired let us know."

Dende nodded, quickly made his way over to Gohan's side, and began his healing process once again.

Everyone else made their way back to lounge area while Bulma and Dr. Briefs began their procedure.

"OK Krillin, you will hear some buzzing sounds, this is normal." His friend said as she initiated the sequence.

"O-OK." He replied. A second later the platform he was laying on slowly slid into the machine. He watched in amazement as the laser lights began to maneuver around him and quickly concentrate on his chest. "Eh?" He sat up slightly, which prompted Bulma to address him.

"Krillin, you need to lie still."

"Oh. Right. Sorry." He apologized, getting back to a resting position. The lights maneuvered once more to concentrate on his chest.

From their computers, Bulma and Dr. Briefs were able to quickly get a high quality image of the surface of the Krillin's heart cells utilizing the previous parameters set up for Gohan. Dr. Briefs brought up the image of the protein receptor they were looking for.

Several minutes went by as Bulma went from one cell to another, scanning the surfaces of each. "So far I'm not coming up with anything. These receptors should be highly apparent by now, correct?"

Her father nodded. "Yes, so far all I'm seeing are normal heart protein receptors. The abnormal one's we witnessed in Gohan don't seem to be here. I think it's safe to say that Krillin doesn't have them."

Even though he was right, something about what her father said struck a cord with her. "Normal heart protein receptors." She muttered to herself as she continued to compare Gohan's heart cells to Krillin's. Then she noticed that the only major difference was that one protein. Almost everything else matched up. Bulma made note of this and Dr. Briefs brought up video footage of the scanning they did for Gohan's heart cells. They analyzed the two side by side. Just from the brief overview Dr. Briefs was able to make a simple observation confirming what his daughter was thinking. "Most of their receptors seem identical, in terms of structure at least." A few minutes went by before he made another conclusion. "And there is one receptor they both have, but Gohan seems to have about 50% less of." He brought up an image of the receptor in question.

"50%..." Bulma continued to think aloud.

And then it struck her.

"50%!" She jumped up, startling everyone in the room. "Dad, quickly set the parameters for Goku's height."

"But we were going to do Dende next." Dr. Briefs barely got his words out before Bulma responded.

"We need to do Goku next!" She ran out into the hall without further explanation.

While waiting in the lounge area to hear of news, Yamcha decided to inquire about Dende's health and stamina. "Do you think he's doing all right?"

"He seems to be doing fine." Piccolo replied, hesitantly. "But he has his limits. He won't be able to carry this on forever."

Just when Goku was about to make a comment he heard his name being yelled at the end of the hall.

"GOKUUUU!" Bulma shouted as she ran towards them. "Goku, we need you in the machine. Now!"

"W-What's wrong?" He asked as he quickly followed her back towards the room. The others followed. Obviously something noteworthy had happened.

"I don't have time to explain. Just come with me." Bulma ordered.

As they ran back into the infirmary, Bulma darted back into her chair in front of her computer. "Quickly, lay down!"

Krillin had just gotten off the platform and Goku was prompt to take his place.

"Hold still!" She continued to shout commands and she typed vigorously away. No doubt she was on to something. The platform slide into the machine once again as the lasers focused on Goku's heart.

With everybody silent, wondering what was going on, Bulma quickly scanned the surface of his heart cells and compared them to Gohan's and Krillin's. As he watched, Dr. Briefs was soon to catch on as to what his daughter was doing. "The proteins!" He remarked.

"The one you had mentioned that Gohan has 50% less of than Krillin, Goku has none of." Bulma commented.

"Then that means…"

Bulma finished her father's sentence. "It's a virus that affects Saiyans!" She then gasped, realizing the full scale of this. While the virus was hard to transmit, it held resilience in the environment outside the body. That meant traces of it could potentially be throughout Capsule Corp.

"We need to get Vegeta and Trunks into quarantine now!"
