Author's Note: My muse suddenly went into overdrive when I was bored during the semesterly break. Don't know if I'll be continuing this but if this gains enough traction, then maybe… Anyways, here's a fic that probably no one wants to read.

Also note that while I've read the VN, watched the numerous animes that it has spawned and read/watched its spinoffs, I do not play F/GO. I merely follow its story, the new Servants and the hilarious comics that surrounds it. That is all.

This chapter is written in only three hours before I left for UNI and haven't been beta-tested so expect some grammatical errors. Thank you.

A Janitor's Normal Day at Chaldea.

Jack was having fun in Chaldea. Not only Jack has a new Mother to be with, but she has other playmates to have fun with! Alice likes to have tea parties and tell stories and Jeanne Lily or Jillian wants to give presents to every Servants possible but she gives hugs and kisses to her counterparts only, which confused Jack but she didn't care as long as they are happy.

As she was strolling amongst the hall of Chaldea, Jack saw in the corner of her eyes a man who's pushing a trolley with janitorial items inside. What's curious about him is that he isn't EMIYA – who's really uptight about cleanliness – but rather he's one of the twenty humans who survived the bombing of Chaldea. This caused Jack to frown as she's angry at the person who dared to harm Mother, the one who gave her a meaning once more. If she had her way, she would gut him and show his insides to Mother.

She shook her head, focusing on the janitor once more. From what Jack can see is that he's Asian, has black hair and has the most tired eyes that she has ever seen. His eyes are even more tired than Mr. Director! The janitor took notice of her gaze and he gave a small smile then continue to push the trolley. Jack blinked and with her curiosity being overwhelmed, decided to follow him. She wants to know as to why he looks tired all the time. She doesn't want to disappoint Mother because Jack knows that Mother would be also curious!

As such, she accompanied him to whatever he's going to do and he didn't protest, with his stance becoming proper and his slouch back straightening. Jack saw him go to every room and cleaning it, mopping the long hallways of Chaldea, gathering the trashes that have accumulated in the Dining Hall and generally improving the cleanliness of Chaldea. Overall, he's doing his job properly.

Although, there are several things that Jack noticed during her observation. One, he didn't interact with the Servants. If there was a Servant in the room, he would wait for them to go outside and when they leave the room, he would immediately clean the place before leaving. Two is that the Janitor isn't that talkative. This is evident when he was in the Dining Hall. When he was picking up the trashes, some of the Servants (EMIYA mostly) tried to offer him help but he declined every single time stating that "You shouldn't bother with something like this." They didn't bother him after that. Lastly, he was efficient. His dedication to cleaning is something that should be appreciated. Not only are the rooms that he cleaned was very… spotless, but he was very capable at his job.

When the sun has set and the moon has risen, they both returned to the place where they've first met. Just as the Janitor was finishing putting back the trolley in the room, Jack decided to spark a conversation.

"Mr. Janitor, why do you look so tired and empty?" Jack asked innocently, tilting her head and not realizing the implication of her words. He stood still at her question, his head snapping towards her. His empty eyes staring back at her. They look each other for a while before he broke it and gave her a placid smile.

"Shouldn't you be playing with the other ones? Also, don't call me Mr. Janitor. It makes me old." He walked towards her, giving her a handshake. "My name's John, John Steward."

She reciprocated back. "My name's Jack the Ripper. Nice to meet you too, Mr. John!" Jack heard him muttering about being old but she didn't bother with it.

"So, are you satisfied with what you've seen, Jack?" The newly identified John asked, maintaining his smile while continuing to place back the janitorial items.

"Nope! We are still curious about you, Mr. John." Jack stated, causing John to sigh.

"And what makes you so curious about me?"

"It's a secret, Mr. John! We like to keep secrets too, you know?" Jack said while pouting in a cute manner. John laughed at her innocent stance even though he knows that he's talking with the famous (or infamous) serial killer.

The Ritsuka twins really did a good job at making her a child once more.

Finishing placing back the items and the trolley, he gave Jack a contemplating look. "Hmm… Is that so? Well then, I guess that I'll see you later."

Watching him leave, she stood there for a while before giggling to herself. She needs to tell this to her friends!

"Did you have fun yesterday, Jack?" Nursery Rhyme or Alice asked as she poured tea into Jack's cup. They're currently in Alice's room, which is filled with so many children's toys and books, which has seemed to fill the entire left side of Alice's room.

"Yeah! One moment, we're having fun and then next you were suddenly gone!" Jeanne Alter's Lily or Jillian states, crossing her arms while pouting cutely.

Jack titled her head at Jillian's statement, in which she gave a giggle. "Oh, that's because We've found an interesting person to follow."

"And who's that person that intrigue you, Jack? Is he one of the Servants?" Alice asked.

"No, he's a Janitor."

This caused both of them to lean forwards on the table, their curiosity being pinged at Jack's word.

On the hallway, John felt a shiver crawl on his back. He ignored it after a while but his statement remains at this head.

"I hope that it isn't something bad."
