(A/N: Made a small mistake in chapter number and had just fixed it)

He was done for. Cliff, wearing a black cardigan, white t-shirt, grey chinos and blue sneakers for the day, kept thinking to himself, over and over, that he would be done for. Once the police match his blood drops to familial DNA from both his mother, father or sister, he would have to go on the run, should they question him. He knew that he was too young to be a Ninja, so he became a samurai. Samurai I, who would take down any goon that got in his way. And when he becomes discovered, Cliff would of course be banned from ever becoming a Ninja at all, and to be forced to retire as Samurai I, put in Kryptarium Prison, and may end up shanked by Killow. Half of the time he thought about it was during school, when he couldn't concentrate on his studies. He looked at his bandaged leg, still slowly bleeding, but was snapped out of his trance when the teacher then spoke up. "Okay, class." His homeroom teacher, Mr. Pale said. "Today, we're going on a field trip to Ninjago Police Station. Don't worry, your parents were sent the permission slips last night and they all approved. Afterwards, we'll be going to Master Chen's for lunch. So, please calmly stand in line so we can head onto the bus."

A tour at the police station. Cliff considered it lucky. If he could get his hands on the blood sample, he wouldn't be exposed and continue being a hero, or in his honorary uncle Cole's case, among others, a vigilante. "Hope the trip goes well." He said to a fellow student.

"I've always wanted to see the inside of the police station." The student replied.

The bus ride to the station was reasonably quiet. It was also Cliff's only opportunity. Find where the sample was, take it without being noticed and dispose of it. Once they had gotten off the bus and it took off, the students all see Cole walk down to them. "Whoa, it's the old Black Ninja." A female student said.

"He's a cop now?" A male student asked.

"Must be missing out on action." Another male student replied.

"Good morning, and welcome to NCPD Headquarters." Cole said as he then looked at Cliff, who nervously rubbed the bruise on his wrist. "Now, I'll be taking you through the police station, so please your bags by the front desk, and you can collect them after the tour." Once the students left their bags by the front desk, signed in, and put on the 'Visitor' tags, Cole leads them into the precinct where many officers were at their desks. "Here is where most of the officers do their work. Study cases, review evidence and search for any known associates or next of kin for victims or suspects."

A student then noticed something. "What's Samurai I doing on there?" She asked, pointing to it.

Cliff turned to see that there were images of himself, in his samurai gear, at Borg Industries, the Domu Library and the museum. "Right now, we are trying to identify who he is. All we know is that he appears to be male with black hair and around five foot six and three quarters, kind of like some of you. Maybe one of you is Samurai I." This gets the male students that had the black haired and were five foot six and three quarters, including Cliff, to object, gaining attention from some of the officers. "Relax. I was being sarcastic." This gets them to calm down. "Once we match the blood sample we obtained when Samurai I cut his leg, we'll find out for sure. Now, kindly follow me to my office, where I'll show you some of my unsolved cases, as well as that one." The students started to walk away as Cliff sees the blood sample in an evidence bag. It was the golden opportunity he had. He makes it to the board to try and grab it when... "Uh, Cliff, please stay with the group." Busted.

"Shoot." Cliff muttered to himself. He dug his hand into his pocket to look at a small device that was his Samurai I helmet and his suit inside of it. He then only had one option. Quit, surrender, and go to prison.

Just outside the station, Pythor was on a rooftop, looking through a telescope to see some officers reviewing the Samurai I case and sees the scroll that he failed to obtain in the museum raid when Samurai I interfered and had all his men arrested. Finding the perfect opportunity, Pythor got out a radio. "Cut the power." He said into it. By a fusebox, a masked mercenary opens it and slams a cinder block at it, causing sparks to come out.

———

Inside the station, Cole was leading Mr. Pale and the students out of his office. "Okay, now to show you where we keep our suspects." He said as the power then shut down, causing all the students to become shocked.

"Hey, who turned out the lights?" A male student asked. Windows being broken were soon heard, followed by punches being blown.

"Someone start the backup generator, immediately!"

———

As soon as he said it, the lights came back on and Cole turned to see Pythor and his goons, about to leave. All the officers around him were unconscious, the board was knocked over, spreading the evidence, and the students had ran to hide in different spots. Choosing not to keep on moving, Pythor smiled as he turned to the detective. "Hello, old chum." He said.

"Pythor P. Chumsworth. Come to give yourself up after all this time?"

"Oh no, I was on my way out. With the scroll. TTFN."

But before he could get out, a net suddenly came in through the broken window, quickly wrapping around Pythor and knocking him on the floor. "You're not going anywhere this time, Serpentine." Cole recognised the computerised voice of Samurai I as he landed his mech in front of the broken window and jumped out of it.

Most of the students were surprised to see him and applaud. "All right, samurai!" One of the students said.

"Now, are you all gonna surrender like your boss?" Samurai I got out his katana and held it out to them. "Or shall I have to use force?"

The masked mercenaries felt like they should surrender, but one chose not to by coming up to the samurai and attempted to punch him. But Samurai forced the flat part of his sword at his arm, making him hit one of his own colleagues, knocking him down before Samurai I manages to grab hold of the reckless mercenary, elbows him and throws him into the other mercenaries. The mercenaries got up to see the samurai just holding out his sword to them. One of the mercenaries had managed to sneak to the side. "Samurai I, watch out!" A female student called out.

Samurai I immediately turned to see the mercenary grab him and tried to grab his helmet. "Nice try." He immediately does Spinjitzu, sending the mercenary into the tornado. He then came at a few others before dispersing and sending the mercenary into the rest of them. But the toss made him lose his helmet. Luckily for Cliff, it landed close by for him to immediately put it back on so they no one would recognise him.

He then stood up to see the unconscious mercenaries before looking down at something. "Hands up." Samurai I turned at the speaker, who was Cole, aiming one of the officer's Glock 17. "Slowly."

"You wouldn't." Samurai I turned his sword around and forced it into the floor before raising it. Cole noticed that he was picking up the incriminating evidence that would lead to his true identity before he holds out his arm and fires the spray, causing Cole to cough before he soon went unconscious.

Just as the officers were regaining consciousness, Samurai I took the opportunity to get back into his mech and it flies off, with the students applauding his heroism. "Oh, samurai." The girls said as the officers start apprehending Pythor and the mercenaries.

In an alleyway just outside the police station, Cliff, changing into his regular clothes that he hid in the alleyway, had taken off his suit, neatly folding it before taking off his helmet and presses a button, turning it and the suit back into the small size. As he puts it in his pocket, Cliff looked at the one thing that would've exposed him. The blood sample. "Finally." He said to himself.

Several Minutes Earlier

Cliff had used the blackout as an opportunity to slip out through the emergency exit before heading into an alleyway to get out his device and pressed it, expanding it to turn into his helmet and suit. "This time, I'll get it and stop Chumsworth." He said as he took off his cardigan.

Present

He smiles at it for a bit before looking over to a nearby manhole, went over to it and dropped the sample down into the sewers. Even if it was found, it would be too contaminated to compare. "Samurai I is still in action." He said to himself before looking up to see an open window to the men's bathroom and decided to climb into it to keep up appearances and avoid suspicions.

———

"GET YOUR HANDS OFF ME!" Was the sentence that Cliff heard as he came out of the bathroom to see Pythor and the mercenaries, who were unmasked, being taken away to the holding cells.

"Pipe down!" An officer replied as Cliff started heading down the hallway and came up to Cole and Mr. Pale as they were counting how many students were accounted for.

"Uncle Cole, are you alright?" He asked.

"Yeah." He replied. "Luckily that spray was a bit further away then before."

"Spray?"

"Samurai I came to the rescue." A male student said.

"But he also knocked Detective Brookstone unconscious." Another male student said.

"Probably also came for the evidence that would expose his identity." A female student said. "Well, I don't care who he is. He will always be a hero, alongside the Ninja. I almost wish they could work together."

"Actually, the Blue Ninja fought alongside him during the museum heist." Cole replied. "But we're still not sure of his intentions. I'm afraid this is the end of your tour. I apologise for the inconvenience"
