1677 and 4201 have no clue what the other two red blood cells plan on doing.

"What the hell is he doing?! He can't take on that monstrosity!" 1677 stated.

The giant mass was continuing on lashing out at the other white blood cells and killer t cells while the two red blood cells tried to come up with a strategy of attack.

"How are we going to go about this without the others knowing what we're doing..." 3803 pondered.

She looked at her hand and focused on it.

"Are we able to focus energy onto our entire hand?" she asked her partner.

2153 gave a frown.

"I'm not sure. We never tried that before."

They looked back at the mass and noticed that something was up there.

"Wait, is that the small penicillin unit I saw a while ago?" 4201 mumbled to herself as she squinted up at PC, who was now hovering at the top of the mass.

A few moments later, 0012 arrived.

They took out something from their backpack and quickly threw it at the mass.

The small device latched onto an area and within an instant began to electrocute it.

0012 turned to the white blood cells and killer t cells.

"I got this cancer paralyzed, now's your chance!"

While the other cells went in for the attack, the nanobot noticed the two red blood cells and motioned for them to join in.

The two noticed them and ran over to where they were standing.

"So, what do you suggest we do? Actually, let me rephrase that. What can we do that won't get us caught?" 2153 asked.

0012 looked back at the crowd of bystanders.

"Actually, you two can help the other red blood cells evacuate the area. That should help hide your secret and prevent some casualties."

The two decided to follow along and went back to the crowd of cells to try and get them to leave.

"Come on everyone! We're all running late on our deliveries. The immunity cells can take care of this without us in the way!" 3803 shouted to the group.

"As for all the other non-immunity cells here, I think it would be a really good idea to not stay here for much longer while that thing is still rampaging! So I suggest that you all evacuate!" 2153 added.

The other cells stopped staring at the mass, looked at the other two red blood cells, and began to run away.

1677 and 4201 were in disbelief.

"They're still not getting out of there. What's her senpai going to think about this?" 4201 muttered.

"Probably that she is really- wait what's going on over there now?" 1677 asked while he pointed at a red blood cell on the floor.

He didn't look like he was dead, but he was trying to stand up.

2153 noticed the hurt cell and realized that he was from his original body.

"I'll be right back", he told his partner before running off to help the other cell.

Around the same time, another red blood cell came running in.

"Hey idiot, aren't those other two red blood cells from your body?" 4201 asked.

1677 squinted at the group of three red blood cells who were in the middle of helping the hurt cell up and pulling him to safety.

While that was happening, 3803 snuck back into the battle and quickly gave a portion of the mass a downright slap and began the dissolving process before she could get caught.

She then backed away and headed back to the others, who were now checking on the hurt cell.

"Are you okay dude?" 1677 asked the cell, who was still sitting on the ground.

"Thanks for helping me get him out of there. It's been a while since I've seen you too", 2153 told the other red blood cell.

"It really has. Glad to see that you are all holding up all right here", the stranger replied.

3803 ran up to the group.

"Sorry for taking so long, something else that I needed to do."

She noticed the other cell.

"So, who's this?"

"Ah right, I never introduced myself. I'm BD7599. I guess you could say that I was overseeing those two in their rookie days", 7599 said with a smile.

They then heard a cough from the sitting cell.

"I guess I should introduce myself too. I'm NC8429. I'm barely starting out, so I guess I can be considered a rookie in that case."

He stood up and faced the other cells.

"It's a pleasure to meet you guys."

8429 bowed.

"And thanks for saving me!"

7599 stood him straight.

"Don't make such a big fuzz over it. We were happy to help!" he told him.

"I guess we should introduce ourselves then", 3803 suggested.

"Good idea. Those two never got a chance to meet us", 4201 agreed.

The two introduced themselves to the new cells and talked.

3803 was focusing on 8429.

She then proceeded to pinch one of his cheeks.

"Ah?! What are you doing?" he asked in slight surprise.

"Well, I took notice of how squishy your cheeks look."

4201 stepped in.

"Uh senpai, I think you should stop that for now. We should probably get on with our deliveries anyway", she suggested.

3803 perked up and gave a nod.

"Ah, you're right! If you want, one of us can go with you on your route", she offered.

"I'll be going with the guy for a bit, maybe give him a boost in self-esteem!" 1677 boldly proposed.

"Dude, I've known you for forever and I think that's a pretty bad idea", 2153 immediately interjected.

"I'll keep an eye on the two then. Our schedules should be able to work in that favor at least", 7599 told him.

"Good point. Alright then, I'll trust you guys to that."

As they were about to leave, they heard a loud thud.

The group turned to the source and saw that the mass has fallen to the ground, slain by the immunity cells.

0012 climbed on top of the mass and began to take samples.

PC was hovering in place at the top and took some of the samples away.

"A mutation of macrophages. Based on the results I was able to gather right now, this mutation was artificially induced in a way", 0012 told themselves.

Killer T Cell backed away from the giant.

"That was a weird cancerous cluster. Now, anyone else finds it weird how there were no macrophages here?"

1146 also backed away.

"Um, I think that this mass consisted of those macrophages Killer T", he pointed out.

"That explains all of these frills then."

1196 looked at the giant.

"How many macrophages did this cluster consist of anyway?"

Eventually 0011 and IB got to the scene, with PC close behind.

"Let me tell you guys, it took a lot to convince the macrophages not to attack this thing!" they exclaimed while pointing at the mass.

"So that's what took you so long. Anyway, did you get a chance to look at those samples?" 0012 asked.

"IB has the results. Show them what you've found."

The unit displayed the results, which revealed something intriguing.

"This was artificially induced. The most probable cause is that they may have eaten something that caused them to mutate. So are you thinking what I'm thinking?" 0011 asked.

"Well based on what PC told us, there is a possibility that they may have had a hand in it. But without solid proof, we can't exactly accuse them."

0012 looked down.

"So what are we gonna do then?"

The nanobot proceeded to stomp on the ground.

"Well for starters, we need to find 0013 anyway. Let's stabilize this mass first and then we can leave this to immunity."

The duo had their thread-like wires come out of their backpacks and stuck them inside the mass and proceeded to electrocute it.

"Okay, you guys take it from here!" 0011 told the group of cells as the two left with their partners.

While immunity was taking the mass away, they failed to notice 0013 observing them hidden behind the corner of a building.
