No spoilers. This time it's not FGO related...well mostly.
____________________________________

        The Clock Tower was not an easy place to work at. (Y/n) was always having to deal with something whether it be delegating orders to the mages who were assigned missions that week or simply paying a visit to the classes taught there. He had no specific job description and was only kept at the Clock Tower because of his servant. Being the lone survivor of a gruesome grail war, he became someone that the Mage's Association wanted to keep an eye on.

        (Y/n) didn't mind it. In fact, he offered to work for them and have his servant participate in some of the missions given so that she wouldn't be bored. Sometimes, on days like this one, he would regret that decision. "This job is so...boring." Mordred was probably having all of the fun out in the field.

        Currently, (y/n) was sitting at the back of a classroom that he was assigned to monitor that day. He personally knew the instructor since he was also a fellow grail war survivor, so (y/n) never bothered to actually do the report like he was supposed to. Lord El-Melloi II always recieved perfect reports no matter what state his class was in. And luckily, he was actually a good teacher because his students performed as well as the reports claimed. But that was besides the point.

        (Y/n) was bored of watching his class. Every now and then, something interesting might happen, but today was not one of those days. Today, (y/n) had his head propped up on his arm and pen in hand as he slept through the whole class. His shades kept any curious students from figuring out his little secret. He perfected his act without even using his magecraft, so that it really seemed like he was judging everything the instructor did.

        The very second that class was dismissed, (y/n) awoke from his sleep and was ready to leave. Only out of courtesy to his friend did he actually stay to at least speak. "I don't see how you do it. I'd have gone insane if I had to be a teacher," (y/n) said as he approached his colleague. Lord El Melloi II turned to face him with the beginnings of a smile forming on his face.

        "You are just lazy. But I guess you would never be the teaching type either way," he said as he handed (y/n) a stack of paperwork. "Try not to overwork yourself. You seem worse off than I am."

        "Yeah, I've been skipping out on sleep to finish things before this deadline. Don't worry about me though. It's my fault for procrastinating this time." (Y/n) took the paperwork and scratched his head a bit. "If I miss this month's check in with Mordred, they might turn on us...haha."

        "Right, that servant. You shouldn't take those check ins lightly. Missimg just one could cause you great turmoil," El Melloi II said. (Y/n) could sense the slight sorrow behind his words. The rider class servant that he had become friends with in the holy grail war that he'd participated in did not survive it. (Y/n) didn't know many details since El Melloi II hardly ever shared information on the matter to anyone, but (y/n) did know that it greatly bothered his friend when such matters were brought up.

        "Look at you sounding all wise," (y/n) joked. "I'll make sure to keep in compliance with the association's guidelines. I wouldn't want you or your students to have to come hunt me down or anything."

        "That's not funny..." his colleague mumbled with a slight pout.

        "Chill out every now and then, man. I'm gonna have to drag you to my place so you can get a taste of the real life. I just got my hands on that new console." (Y/n) grinned when he saw his friend's eyes widened in surprise. "Come by and get your ass kicked some time. I might even go easy on you every now and then."

        "Heh, you're funny. There's no way you can actually beat me in any game. You've never gotten a single win against me," El Melloi II almost laughed aloud at such an accusation.

        "Yeah, whatever teach. You've been in retirement for far too long. I'm definitely going to beat you. Anyways, I should head out before-"

        "Oi, shield bastard!! Get back here!" Of course it was Mordred who had spoken having just entered the room. Galahad, the white cat she had strangely used her grail wish on, had escaped her hold and ran towards (y/n) who sighed at the scene she was causing.

        "Good luck with that." (Y/n) rolled his eyes at those parting words.

        "Really, Galahad? You're a smart cat, don't drag Mordred into trouble," (y/n) scolded the cat as he picked him up. Galahad deadpanned at him. Yes, the cat deadpanned and gave a meow that sounded as if he had some sort of attitude. "Mordred, if you keep breaking the rules like this, you'll be exterminated. Why don't you just wait for me to get back?" (Y/n) had started to leave the classroom with Mordred following behind him.

        "Do you know how boring it is to sit in a room alone with someone who annoys you to the ends of the earth and back? If I didn't enjoy tormenting him, I'd have never brought shield bastard with me to this modern world. Although, anyone else would have been far worse to deal with."

        "Mordred, his name is Galahad and he is a cat." (Y/n) pointed out. Galahad stuck his tongue out at Mordred when (y/n) wasn't paying attention.

        "Yeah, sure. He's a cat. That changes nothing." Even after a year and a half, (y/n) still didn't understand why Mordred kept a love-hate relationship with the highly intelligent cat. (Y/n) had never bothered to ask either.

        "How did the mission go. You didn't have to borrow any of my magical energy this time. Was it that easy?" He wanted to change the subject before they got back to his heavily guarded home. Mages were stationed outside all day, everyday just in case the Association ever saw Mordred as a threat.

        "Too easy. Kind of boring actually. And I told you, for the millionth time, I'm not the one using your magical energy. You're just not careful and don't notice when stuff around you happens. And give me back my cat," Mordred said. She reached out for Galahad, but (y/n) didn't let her take him.

        "He always disappears whenever you leave. Let me at least carry him for a bit," (y/n) complained before proceeding to pet the cat. Galahad purred a bit at the affection.

        "What do you mean he disappears?" Mordred suddenly sounded alarmed which put (y/n) on edge.

        "Whenever you go on missions, he leaves and doesn't come back until you do. I used to think he went with you until I saw him outside a few times with the guards. I don't know why he does that. Why does it seem like it'sa bad thing that he's leaving?" (y/n) spoke. Mordred shook her head at him.

        "Wait until we get out of this building," she muttered. Once they were outside, she took the lead and guided them to a clear alley. "Could you use your ability? The Association doesn't need to know about this yet." Mordred's seriousness in the matter was starting to make (y/n) worry. He handed Galahad over to her and performed his spell. As an illusionist, he could easily change the perception of any onlookers or even listeners, building an entirely different conversation from nothing as a cover if necessary.

        "Okay, what's going on? You know we can't do anything that will make the Association target us. We may be on their side, but you know how they are." He wanted answers just in case he'd need to start planning for a possible disaster.

        "Shield bastard, how long has this been happening?" Mordred asked the cat rather than starting her explanation. She got an annoyed hiss from the feline. "And you didn't say anything?! Do you want to go back to being a dead distant memory? You know what, forget it," she sighed in frustration, putting Galahad down. "Galahad isn't a cat. And you've been in danger ever since the war ended. It's not that I didn't want to tell you. The more aware you are of their presence, the easier it is for them to find you. The holy grail-"

        "It's actually evil. I know. The Association warned me that there might be lingering evils waiting around for my downfall. But what does it have to do with whatever is after me? I fought alongside you in that war. I can handle a fight or two," (y/n) said. He was a little upset for being kept in the dark. Sure, he noticed that things seemed off every now and then, but he trusted Mordred more than anyone he knew.

        "You by yourself are no match for a servant, even if they are shadow servants. The grail wants you and I dead. Galahad is your protector when I'm not around. I used my wish to bring him her because I knew I wouldn't be able to be nearby at all times. I failed to realize that during the war, and it almost costed us our lives. I wasn't taking that risk again," Mordred snapped.

        (Y/n)'s gaze on her softened a bit. "Mordred, stop doing everything on your own," he pleaded. He pulled her into a hug without warning, causing her to nearly attack him. Despite nearly taking a hard hit, it was definitely worth it when she calmed down and rested her head on his shoulder. And then Galahad hissed in alarm and ruined the moment.

        (Y/n)'s illusion broke having been attacked from the outside. He pulled Mordred to the ground and shielded her as the brick walls around them exploded. The attack had been too sudden for (y/n) to escape it. Even Mordred couldn't have keep them both from being harmed in such a short time span. But someone else could.

        (Y/n)'s head throbbed in pain as he tried to recover from the aftershock of the attack. His vision was blurry and his ears rang. The most he could see was the silhouette of someone standing in front of him and Mordred.

        "Mordred get you master...here, now!" The unfamiliar voice came and went.

        "No, you do it. What do you...summoned you here for!" (Y/n) clung tightly to his servant knowing that she was attempting to send him off and fight alone. He uttered the words needed for another illusion and attempted to stand. At least his magecraft could by them some time, but whoever attacked was bold enough to do so right near the Clock Tower.

        "Mordred, didn't I just say not to-" his words were interrupted by another explosion. This time Mordred shielded him, but no harm came to any of them. Even so, a second round of attacks was enough to render (y/n) unconscious. His illusions thrived when he was not awake, but he hated it when that side of him took over. The illusions could affect anyone and could grow out of control which was another reason the Mage's Association kept an eye on him. He felt sorry for his enemies, but not sorry enough to forgive them for underestimating him.

        When he woke up, he could immediately tell that he was far from danger. "Oh. I guess it's too late now then..." that same unfamiliar voice could be heard saying as (y/n) sat up from his couch. He was safely at home in the company of a white haired stranger. The damp rag that was on his forehead fell into his lap. "You weren't supposed to see me like this. Now Mordred's going to yell at me," the boy spoke with a sigh.

        "Galahad?" he was unsure if his guess was right, but his cat was missing and Mordred had already told him that Galahad was no cat.

        "Yes? You have a question? Or maybe two?" the boy answered. He seemed far more polite than the cat (y/n) knew. No questions could be asked before Mordred was heard entering the living room.

        "Oi, shield bastard! Go do a perimeter check or something. Master isn't supposed to see you when you aren't a cat," she called. When she got within view of them, she froze with her bag of chips and stared at them.

        "Too late," Galahad mumbled. He looked off to the side already flinching before Mordred began to fuss, but he looked back to her in surprise when she kept quiet for a moment.

        "The Association is meeting right now about shield bastard. Someone saw him defending you earlier. They think you summoned him. I tried to explain that he's a cat, but they wouldn't listen. That teacher guy is trying to help you out," Mordred informed. "But aside from that, everyone was safe. You didn't affect anyone with you magecraft this time. You actually helped us out a lot." She looked at Galahad before speaking again. "And quit using up master's magic energy. You're probably the reason it took so long for him to wake up."

        "What makes you think I want to go back to being a cat," Galahad said.

        "There it is. I was wondering why you were being so polite earlier. Looks like Mordred has rubbed off on you," (y/n) noticed. Galahad blinked at him but said nothing to deny his words.

        "Yeah, I helped him learn how to break some rules. The kid never knew how to live back in Camelot," Mordred boasted about her successful attempt to corrupt Galahad.

        "I cannot even find the words to describe how much I hate you," Galahad mumbled.

        "Oh? More hate than what you have for your father?" Mordred sneered, obviously looking to start of fight. The glare that Galahad shot her prompted (y/n) to interfere before things went too far.

        "That's enough. If you're going to fight, you might as well do it the legal way. We're stuck here, so I might as well get some practice on my new console before Wa- I mean...Melloi gets the chance to stop by." Mordred nor Galahad seemed to have a problem with the proposal. The two were able to safely fight things out in Super Crash Sisters Ultimate without issue. It wasn't long before Galahad got frustrated from losing to Mordred and decided to take his place as a cat again. Seeing him change back was quite an odd sight, but once he was the familiar feline again, things seemed as if they were almost back to normal.

        "It's getting late. We should get a good night's sleep just in case it's the last one we can safely have without looking over our shoulders," (y/n) suggested as he powered off his console. He plopped down on his couch with a sigh. "I don't plan on letting them get rid of either of you. It wouldn't be right, especially with how dangerous I am already."

        "You worry too much, master. I think you a long time ago to leave things to me. I'm a knight, it's my duty," Mordred spoke, taking a seat next to him. Galahad meowed in agreement before walking off into the far reaches of the home. Knowing that the cat was actually a servant of sorts didn't change how (y/n) viewed him. Being an illusionist just let him brush things off sometimes.

        "Did I...really not harm anyone today? The illusions get bad when I'm in the most danger. Tell me the truth, did you have to fight me?" (y/n) solemnly wondered.

        "The hell did I just say? Quit worrying. Take your mind off things and be a little more carefree. I swear, everyone is always so serious." (Y/n) gave her words a bit of thought even though he really wanted her to answer his question.

        "You make it sound like something so easy, but I wouldn't even know where to start..." he said.

        "Then start with this." Mordred stole his breath away, kissing him without warning. Despite that, he was quick to return the action, going so far as to pull her by the waist. He nearly let out a slight yelp of surprise when she pushed him down against the couch, but she pulled away from him soon afterwards. "You always fall for that," she boasted.

        "I don't have a problem with it. Never have, never will," he said with a laugh. But even in the moment of happiness, he couldn't shake the feeling that something wasn't right. How much of his life was just as it seems? Just what was an illusion and just what was real? Only Mordred knew as she and Galahad watched over (y/n)'s unconscious body, defending him against shadow servants and even (y/n)'s own illusions that destroyed the grail just moments after his war victory. It was only a matter of time before things went from as they seemed to as they were.
______________________________________

So I may have decided to take a sudden dark turn there. Haha...whoops. I also thought it would be interesting to include Galahad in a oneshot even though Mordred is probablythe only knight of the round that doesn't highly favor him. Anyways, I feel better now that I didn't simply reuse a previous idea. Until next time you awesome readers!
