Hey, mina! Chapter 4 is up and ready to read. We're making that time jump, so this chapter is picking back up where Chapter 1 left off. If you need a refresher, re-read the end of that chapter. Of course, this means Chapter 3 is still a cliff-hanger. Sorry. I promise we'll pick that plot back up next chapter.

Anyway, as always, read and enjoy! (and tell me if you did by clicking "review" at the bottom of the page.)

And again: I don't own Rockman!

Chapter 4: Lightman.EXE

Everyone in the lab turned around as they heard the door open and close.

"Enzan-kun!" Meijin greeted pleasantly.

"Where is he?" Enzan asked.

"Who?" Hikari-hakase returned.

"The new navi you programmed. Lightman, I think," Enzan answered rather crossly, though his bad mood was not meant to be directed at the scientist. For a reason he could not explain, something about meeting Lightman had put him in a sour mood.

The scientist turned to the monitor he had been at. "So that's where you two were," he stated to what Enzan assumed were Rockman and Lightman. His assumption was confirmed when he heard a hesitant laugh, probably from Lightman.

The large monitor in the room then came to life as the twin navis appeared on it.

"Konnichiwa, Enzan!" Lightman sing-songed.

Enzan didn't answer. He carefully studied the newcomer, who seemed to falter under his gaze. Lightman looked exactly like Rockman, down to the brilliant and unmistakable green eyes. The only way to tell them apart was that Lightman's color scheme, though while still blue, was composed of lighter shades. The only exceptions to this were the stripes which were dark blue.

"Um, Enzan?" Lightman cocked his head to the side.

"Why?" Enzan asked as he turned to Dr. Hikari.

The question caught the scientist off-guard. "Huh?"

"Why did you program him?" he indicated Lightman, who was wearing a rather blank expression.

"To keep Rockman company."

A million thoughts went through Enzan's mind. He had so many questions and he did not know where to begin. However, the most prominent one on his mind was why did Lightman bug him? But of course Hikari-hakase would not have the answer to that one.

He jumped slightly when Meijin placed his hand on his shoulder. "It's what Netto wanted," he said quietly.

He turned back to the navis on the screen. He noticed that Lightman was shifting uncomfortably.

"So why like Rockman?" Enzan asked Dr. Hikari.

"Um, well…it just seemed to fit," Dr. Hikari answered rather pathetically. Enzan's eyes narrowed. Something was going on here. But what?

"Okay. How long has he been here?" Enzan continued.

"Hello, I am in the room, you know!" Lightman interjected crossly, folding his arms. Enzan glared at him and the poor navi seemed to shrink back a bit.

"He's been here about a month," Rockman answered, taking a hold of Lightman almost as if in defense.

"Then why wait until now?" Enzan continued his interrogation.

"Wait until now? You mean to introduce him?" Dr. Hikari asked. Enzan nodded. "To give both Rockman and Lightman some time to adjust."

Enzan was quiet and did not continue his questions. He felt overwhelmed. Slowly he began to realize why Lightman bugged him—he wasn't necessary. He was simply here to…to, well, help everyone get over…

He closed his eyes, fighting back painful thoughts. It had been 3 months since Netto had… Enzan's face and fist tightened—he couldn't bring himself to remind himself. Lightman was not necessary! That's what upset him! All Lightman was was a reminder! He didn't need that! Rockman certainly didn't either!

Enzan turned and left the room without a word.

Lightman reached out, as if to stop him. Rockman gently held him back.

"Enzan…" Lightman whispered.

--------------------

"Enzan-sama? Are you okay?" Blues asked quietly as his netop walked down the hall.

Enzan sighed. "No. What was Hikari-hakase thinking when he programmed him?"

Blues did not know how to answer, so he didn't.

The two existed the Sci-Labs in silence and quietly got into Enzan's limo. Enzan stared out the window, watching the world pass by, but not noticing as it did. Netto kept creeping into his thoughts despite Enzan's mental protests. Netto always had been persistent, the idiot. He sighed. Stupid Lightman. Why did he have to remind him of Netto?

Why did he remind him of Netto?

Enzan's mind began the race. The battle. The interrogation at Sci-Lab. Lightman was like Netto! Dr. Hikari had programmed Lightman to be like Netto!

"What was he thinking!?" Enzan exclaimed out loud.

"Enzan-sama?"

"Hikari-hakase programmed Lightman to be like Netto!"

"You can't be serious, Enzan-sama," Blues answered.

"That's why that navi bugs me! How could Hikari-hakase do something like this!?" Enzan continued, almost enraged, though his voice gave a sense of one feeling hurt.

"Maybe it was Hikari-hakase's way of coping," Blues offered meekly.

Enzan pulled out his PET and looked at the red navi. "But, it's not right. Especially to Rockman…" Enzan began, suddenly drained of his upset feelings and a weariness taking its place.

"Actually, I don't think Rockman minds," Blues said. Enzan looked at his navi, silently asking him to explain. "Rockman was smiling during the battle, remember? No one has seen him do that since…"

"No one's really seen him since the funeral, Blues," Enzan cut in. "He kept to himself, despite everyone's efforts."

"But he came back out and he's starting to be himself again. Maybe Lightman has had a lot to do with that," Blues continued. His voice then dropped into a sad whisper: "Rockman's moving on. Why can't you?"

Enzan turned to stare out the car window again. "It still doesn't make it right, Blues," Enzan said quietly. The pair sat in silence as Enzan continued to watch the world pass by as the car headed home.

--------------------

Rockman looked at Lightman with concern. He hadn't said a word since Enzan had left and he seemed to be staring aimlessly into space as they watched the various navis and programs rush about, working on the latest projects.

"Are you okay?" Rockman asked the lighter navi.

The other blinked as he was snapped out of his thoughts. "Huh? Oh, yeah," the other answered once his mind had returned to Earth, though Rockman could tell it still wasn't all there.

"Is it about Enzan?" Rockman asked.

Lightman frowned and looked down at his boots sadly. "Yeah," he answered. "If you ask me, that could have gone a whole heck of a lot better."

"Maybe," Rockman said as he turned back to continue watching the various activities of the Sci-Lab Network. "But I'm sure it came as a surprise to him."

Lightman looked back up and joined his partner in watching everything going on. "We're talking about Enzan. You would have thought we would have told him the truth."

"You're not going to, are you?" Rockman asked, slightly alarmed.

"Heck no!" Lightman responded, some of his liveliness returning, but it quickly left as he continued, almost in a whisper: "I think I'd like to wait longer until we tell everyone else." Rockman looked at Lightman as the lighter of the two looked up at the digital sky. "If Enzan reacted like that, I'd hate to see how everyone else will." He sighed. "I'm not ready for that."

Rockman smiled understandingly. "You're not regretting this, are you?'" he asked.

Lightman looked at the darker blue navi in surprise. "Of course not!" He said. "I mean, I don't like having to pretend I'm meeting everyone for the first time..."

"Which you failed at today," Rockman cut in jokingly.

"Ha ha, very fun," Lightman said sarcastically. Rockman just smiled at Lightman, who returned it. "Like I was saying, before I was rudely interrupted, I hate having to pretend I'm meeting everyone for the first time and not being with them, but," Lightman turned to face Rockman and looked directly into his eyes, his own eyes sparkling with light, "it's all worth it if I'm here with you."

"Netto-kun…" Rockman whispered.

Lightman laughed and covered Rockman's mouth playfully. "You've got a big mouth! Lucky no one heard you."

Rockman wiggled himself free. "Gomen, Lightman."

Lightman shrugged. "I don't care if no one finds out, niisan."

"Lightman!"

Lightman laughed. "What? Technically, niisan is fair game because we're twin navis. It's only if I add the Sa…" the rest came out muffled as Rockman clasped his hand around his brother's mouth.

Lightman laughed as we wrenched free of the hand. "How about Rock-niisan?"

"What?" Rockman asked, then shook his head. "For now, let's just stick with Rockman and Lightman, okay?"

"Why?" Lightman asked.

"Just for the sake of others and the situation," Rockman answered. He then smiled. "But at home, I'd be happy to have you call me niisan, if I can call you toutousan. We just need to wait until everything settles down until it can be a public thing."

"Sounds good, niisan." Lightman grinned innocently when Rockman gave him his look of disapproval, the exact response he had been going for.

"You're unbelievable," Rockman said.

Lightman grabbed onto his brother's arm. "And the amazing thing is that you love me anyway," he said.

Rockman couldn't but help smile again, happy that they were together. After all, it was only together that they had been able face anything and everything.

--------------------

So now you know who Lightman is! I hope this doesn't ruin the story for you all. I promise that there are still more things to come, even if you know Netto's ultimate fate. So please keep reading and reviewing!
