Author's note: For those that are wondering when's the Proto-Merlin chapter, that's coming up next :) Also, this was based of a FGO 4Koma.

"Hey! Get back here! And that's my spear!"

"Nope! Not on my watch! And plus, you're me, so technically, it's already mine!"

"Not in this case Caster! Give it back!"

"Never!"

Right now, Lancer Cu was chasing his Caster counterpart throughout all of Chaldea.

And why?

Simple. Caster Cu was holding Gae Bolg in his hands, and he didn't want to part away from it.

And it all started because of Cu's napping...

(A few hours ago...)

Lancer Cu was sleeping on the couch in one of Chaldea's recreational rooms, with his spear in the corner of the couch. As he was sleeping, a servant happened to pass by.

That servant was Boudica, the Queen of Victory.

Right now, Boudica was carrying a basket of laundry after she came out of the laundry room. However, she was having a problem as the usual dryer in the laundry room was broken. "Hm, what should I do? There's this many dirty clothes that needed to by dry, but the dryer now is broken for some reason...what should I do?"

It was then that she came across Cu sleeping and then saw Gae Bolg in the corner.

"Hm...I could use that as a drying rack...I hope that Cu doesn't mind if I borrow it for a moment. I'll give it back to him later when I see him..."

And then she carefully grabbed Gae Bolg from the corner and quickly left the room.

After a few minutes of sleeping, Lancer Cu woke up from his nap with a yawn. "Man. That was a good nap..."

However, when he woke up, he noticed that Gae Bolg was missing, and he was freaking out a little bit. "Hm? Where's Gae Bolg? Who took my spear?! Where is it?! Great, if shishou or her counterpart or both of them find out that I lost Gae Bolg, they'll have my head on a silver platter...I need to find it now!"

And in an instant, Lancer Cu quickly got off the couch he was sleeping on and headed out in the hallways of Chaldea. As he was searching for Gae Bolg, he asked numerous servants to see if any of them saw his spear.

And sadly, none of them saw it.

"Tch, this is getting nowhere..." he thought as he continued walking. As he continued walking, he bumped into a certain servant.

EMIYA.

"Oh. Hey there lancer," EMIYA said.

Lancer Cu sighed. "Hey, Archer! Have you seen my spear?"

For a moment, EMIYA was silent upon hearing Lancer Cu's question. Then he turned his head slowly and said, "I...haven't..."

At that moment, Lancer Cu knew he was lying and grabbed him by the shoulder. "Liar! Such a blunt reply...you know something, don't you!? Say it!"

EMIYA sighed as he now knew that Lancer Cu was not going to take any bullshit from him.

"All right, fine. I did see your spear."

"Where is it?!"

"Well...it seems that when you were sleeping at one the recreational rooms, Boudica came by while carrying the laundry. Apparently, what happened was that earlier, the dryer in Chaldea's laundry room was broken. Boudica was troubled by it and so...she happened to look upon your spear..."

For a moment, EMIYA was silent before Lancer Cu yelled at him.

"What?! What happened next?" Lancer Cu asked.

EMIYA took a deep breath before continuing. "She used your spear as a drying rack..."

Lancer Cu was shocked and deadpanned upon hearing what EMIYA just said. "What?"

"Yeah. She used your spear as a drying rack," EMIYA repeated.

Lancer Cu was silent for a moment before yelling, "Well why didn't you stop her?!"

"Well, it looks interesting at the time, so I just watched and let her do her business!" EMIYA replied in defiance.

"You bastard!" Lancer yelled as he now knew that his spear was being used as a drying rack. After a few seconds of calming down from his outrage, he continued the conversation. "And? Where's missy Boudica?!"

"Hm...she's probably still in the laundry room by now," EMIYA replied.

"I see. Thanks then. I'll still remember this Archer..." Lancer Cu muttered as he headed towards to the laundry room where he should find Gae Bolg along with Boudica. As he was walking towards the laundry room, he had a few thoughts going through his mind. "I swear, why does missy Boudica think she can use my spear as a drying rack?! I mean seriously! That spear is a gift from shishou you know! It's not supposed to be used for something that mundane!"

Eventually, Lancer Cu was getting close to the laundry room, hoping to see both Boudica and his spear. "Hey! Missy! Sorry, but can you return my spear..." he asked as he arrived in the room.

However, when he arrived in the room, what he saw was Boudica...and apparently, Caster's Cu staff instead. Lancer Cu was surprised at what he was seeing. "Huh?!"

"Hm? Oh, hello Cu Chulainn...?" Boudica said.

For a moment, Lancer Cu was speechless at the sight in front of him. Then after a few moments of silence, he began to speak.

"Um...missy, where is my spear? From what Archer told me, you used it as a drying rack, correct?"

"Yeah...sorry for not asking you earlier..." Boudica sheepishly replied with a chuckle.

Lancer Cu sighed. "Where is my spear?" he repeated.

"Oh, your spear? Well...the thing is that I was using it earlier until the Caster version of you came by and took it...and in exchange, he lent me his staff..."

At that moment, Lancer Cu felt burning rage at his Caster counterpart for taking his spear. Not to mention the fact that he also imagined what face his Caster counterpart was making right now upon having Gae Bolg.

"THAT BASTAAAAAAAAAAAAAAAAARD!"

And in an instant, Lancer Cu immediately left the laundry room and started running around in Chaldea's hallways to find his Caster counterpart. "I SWEAR, WHEN I GET MY HANDS ON MY CASTER COUNTERPART, I'M GOING TO KICK HIS ASS!"

Eventually, after many minutes of running around in Chaldea's hallways, Lancer Cu eventually found Caster Cu in the hallway, who was admiring Gae Bolg.

"HEY! CASTER ME!" Lancer Cu yelled.

Caster Cu stopped looking at Gae Bolg for a moment and turned around to see an angry Lancer Cu in front of him. "Uh oh..."

"GIVE ME BACK MY SPEAR!"

"NEVER! IT'S MINE NOW!"

And thus, the chase between Lancer Cu and Caster Cu began...

(Back to the present...)

"Well, this is not how I want to spend today! Instead of enjoying myself while taking a nap, I'm spending today chasing after my Caster counterpart for my spear! I mean come on! He just can't take my spear and call it his! Even though he may be me, it's not his weapon!" Lancer Cu thought as he was chasing his Caster counterpart.

"Finally! After many years, Gae Bolg is mine! I can finally use it again! Sure, this may be my Lancer counterpart's weapon, but he is me. Therefore, it also belongs to me as well!" Caster Cu thought.

As Lancer Cu continued chasing after Caster Cu, it was then that they passed by two certain people.

Ritsuka and Mashu.

"Hey Mashu...was that Cu chasing after his counterpart?" Ritsuka asked.

"Yeah...and it seems that the Caster version of him was carrying his spear senpai..." Mashu replied.

Ritsuka sighed. "I've got a bad feeling about this..."

"Me too senpai. The destruction those two will cause...we're going to stop them now."

"Agreed."

And soon, Ritsuka and Mashu soon followed the trail of the fighting...

Right now, Lancer Cu was still chasing his Caster counterpart throughout the hallways of Chaldea.

"Jeez! I know he's the Lancer counterpart of me, but how much stamina does he have to keep running like this?!" Caster Cu thought as he continued being chased by his Lancer Counterpart.

"Come on...almost there..." Lancer Cu thought as he was getting closer to his Caster counterpart. As he got closer to him, he instantly jumped onto him. "Gotcha!" he yelled as he landed himself onto Caster Cu.

"Hey! Get off me!"

"Not until you give me back my spear!"

"Never!"

And then a fight broke out between Lancer Cu and Caster Cu. For a while, both of them were punching and kicking each other while they were rolling around on the ground throughout in Chaldea. As they were fighting, some of the servants looked at the fight.

And to some of them, it looked like a fight from a cartoon, minus the special effects, sounds, and the dust cloud.

"Ow! Take this!" Lancer Cu said as he punched Caster Cu in the face.

"Oh yeah?! Well, take that!" Caster Cu replied as he kicked Lancer Cu in the stomach.

Soon, Ritsuka and Mashu found where Lancer Cu and Caster Cu were fighting against each other, and they were still fighting each other. Ritsuka then yelled to stop the fighting. "YOU TWO, STOP FIGHTING!"

Upon hearing Ritsuka's yelling, Lancer Cu and Caster Cu immediately stopped fighting each other. As they let go of each other, they greeted Ritsuka.

"Hey there kid..." they said in unison.

Ritsuka took a deep breath. "Lancer Cu, Caster Cu, why were you to fighting against each other?" he asked with a bit of scolding in his tone of voice.

Lancer Cu then pointed at his Caster counterpart. "It's because he took my spear!" he yelled.

"Is that true Caster Cu?" Mashu asked.

"Yes..." Caster Cu replied.

"Why though?"

"Well...I just want to use Gae Bolg one more time."

Ritsuka and Mashu deadpanned upon hearing Caster Cu's answer. "So, let me get this straight. The reason why the fight between you two started was because you wanted to use Gae Bolg?"

"Yes."

"And how did you acquire it in the first place?"

Caster Cu let out a sigh. "I got it from missy Boudica in which she was using it as a drying rack because the dryer in Chaldea's laundry room is broke, and in exchange for getting Gae Bolg, I let her borrow my staff. How she got it was that she borrowed it when my Lancer counterpart was asleep."

Ritsuka and Mashu were surprised at how the whole thing started. "Is that so?" Ritsuka said.

"Yeah."

"Great. Now if you will excuse me," Lancer Cu said as he took Gae Bolg back from his Caster counterpart.

"Hey! That's my spear!" Caster Cu yelled.

"Not anymore!"

"Why you...!"

And Lancer Cu and Caster Cu were growling at each other.

For a moment, Ritsuka was examining the issue that was in front of him. "Hm...so this whole thing started because Caster Cu wanted to wield Gae Bolg. Normally I would call that stealing, but...considering that they're the same person although from different classes, it's hard to tell if it's stealing or not. Hm...what to do here?"

It was at that moment that Emiya Shirou came into the scene. "Hm? Master? Mashu? Cu?" Shirou said, snapping Ritsuka out of his thinking.

"Shirou?"

"Shirou-san?"

"Kid?"

"Shirou? What are you doing here?" Ritsuka asked.

"Da Vinci asked me to come to her workshop earlier," Shirou replied.

At that moment, an idea came into Mashu's head. "Shirou-san is here...wait a minute, that's it!"

In an instant, Mashu quickly rushed to Shirou's side, confusing everyone for a moment.

"Mashu?"

"Shirou-san, I need to borrow you for a few seconds. Do you mind?"

"No."

"Great! Follow me for a moment," Mashu said as she gently dragged Shirou to a corner of the hallway. As they were far away from Ritsuka, Lancer Cu, and Caster Cu, Mashu then whispered something to Shirou.

Meanwhile, Ritsuka, Lancer Cu, and Caster Cu were wondering what just happened to Mashu and Shirou. "What the heck just happened?" Ritsuka asked.

"I don't know," Lancer Cu replied.

"Me neither," Caster Cu said.

After a few seconds, Shirou and Mashu returned. "Everyone, I think I may have a solution to both of your problems here," Mashu said with a smile on her face.

"Really? What is it?" Lancer Cu asked.

"Shirou-san, if you would please."

Shirou then stepped forward. He then brought out his arm and said, "Trace on."

In an instant, a copy of Gae Bolg appeared in his hands. "Will this do?" he asked.

For a moment, everyone besides Mashu was speechless at what Shirou just did. Then after a few minutes of silence, Lancer and Caster Cu started laughing.

"Of course! If I ever wanted Gae Bolg, I could have asked the kid to make a copy of one! How did I forget?! Heck, this isn't the first time he's done this!" Caster Cu said as he was laughing.

"Wow! I can't believe I forgot about the kid's magecraft abilities! Jeez, if I have realized this earlier, things would have ended differently..." Lancer Cu said with laughter in his voice.

Ritsuka let out a sigh as the problem was hopefully fixed. "Anyways, will this do?"

"Yeah, sure. Give me the one the kid traced."

"Got it. Shirou?"

Shirou then handed Caster Cu the traced Gae Bolg, in which Caster Cu accepted gleefully. "Great! Now I can work on my spear skills! Thanks kid!" Caster Cu said as he soon left.

"Well, at least this is over. Now it's back to napping. Thanks kid," Lancer Cu said as he left the hallway.

Ritsuka and Mashu let out a sigh. "Well, at least things didn't go wrong huh, senpai?" Mashu asked.

"Yeah Mashu," Ritsuka replied.

Meanwhile, Shirou was confused with what just happened. "So...what did I miss?"

Ritsuka and Mashu sighed. "It's a long story..." Ritsuka said.
