Author's Note: Hey everyone, I am back again. This is the side project I mentioned back in the last fanfic. I'm in a big Three Houses mood as of late and I wanted to do this story to flesh out the twins's character while also having them learn more about the other smashers. I thought the best way to do this was a tea time, just like in Three Houses. I'm gonna be doing chapters in the number order like in Ultimate's roster, however I will combine some characters together since not a lot of them have that much depth. This is also a collaborative effort with Gintaxalvissforever, since Three Houses is her favorite game right now and she loves Byleth. We brainstorm a lot together about this and we think it'll be fun.

Anyways, enjoy this chapter. If you like what you've read, be sure to favorite and follow to kerp updated. Reviews are always appreciated

Oh just to clear up some stuff you get confused on where Byleth and Beth are at the point of Three Houses. Jeralt is dead. During the previous story, they got summoned before they went after Kronya. So they never merge with Sothis. Also this is the Golden Deer route.

Beth is making her way back to her and Byleth's room. She had just finished training with Ike. The female professor has some scratch marks and bruises on her face and her hair was very ruffled and messy. She didn't care though. Beth loves the thrill of a fight and everything that comes with it. Being a former mercenary, getting bruises, breaking a few bones, and shedding blood was the norm of fighting. All that mattered is that you come out of the fight alive. That was her way of thinking.

Beth reaches her room and slowly opens the door. "Hey Byleth you in he-" The female professors eyes widen at the state of her room. There are piles of written papers scattered all over the floor. Pictures of every smasher in the mansion taped all over the walls with marker lines drawn between some smashers with some notes on the side of pictures. Beth turns to see her twin brothers looking at the wall of pictures.

Byleth turns to his sister to reveal his baggy red eyes and messy hair. "Sister. You've come just in time to see what I've been working on for the past twenty four hours."

Sothis appears next to Beth with a very annoyed look on her face. "All he's been doing is working on this project of his. No food. No sleep. Disturbing my beauty sleep while he's busy taping pictures to a wall and asking me trivial questions I don't care about. He has completely lost his mind. I've been trying to get him to sleep for hours, but he's too stubborn. I just gave up after ten minutes."

Beth walks to Byleth. "Bro, what is all this?" She asks, pointing at the wall of pictures.

"I can explain. So, you know how I spent all the time figuring out all of our students likes and dislikes? I spent all day yesterday examining every fighter in the mansion and taking notes of all their likes, dislikes, and relationships with each other. I did get a little help from Yuri to find out about some certain things." Byleth answers.

"You did...all of this? In one day? With no food? No sleep?"

"Affirmative. Let me run through everything for you. It is quite an adventure. So, Mario and Luigi are brothers. They both have girlfriends who are princesses, Mario is dating Peach and Luigi is dating Daisy. This monster Bowser has feelings for Peach and he hates Mario. So I drew a line indicating the love triangle between the three. You can see there are three people named Link here, but they all actually come from different universes. Same with Zelda and Ganondorf. The only ones who share a universe together are Ganondorf and Young Link, who is the non cartoonish Link. Then I shall direct you over here to Chrom, who is the king of Ylisse. He is the father of Lucina who has come from the future and they are both descendants of Prince Marth up here. Lucina is married to a dark angel named Dark Pit who is a clone of this angel Pit and they both work under this goddess named Palutena. By the way, Pit is dating this tactician named Robin who has a twin brother named Rob."

Beth slowly nods. "Mmhmm. I see." "I am completely not following any of this." The female professor was getting a headache listening to all this exposition dump.

"That's not all, I got a crazy story for you." Byleth points to a picture of Corrin. "This is Corrin, he is a king. He also has a twin sister named Kamui. Corrin is currently dating Bayonetta. However, I discovered that Bayonetta had an affair with this guy, Cloud. Cloud was dating Kamui around that time, but now they've broken up. This is a little confusing because there's still some feelings between Cloud and Bayonetta. Corrin, Cloud, and Bayonetta all have a very close relationship with each other. This is very bizarre."

"So that kid got cucked huh? Poor guy. I almost feel bad." Beth shakes her head. She turns to her brother. "Did you really need to do all of this? This seems a little much don't you think?"

"I needed this research sister because I'm setting up for something. I am going to have tea time with each individual fighter here, and you're going to help me."

"What? Why the hell do you need my help? You did all this damn paperwork already, you're capable of setting up a tea time without my help."

"You know I'm not that strong speaking to others. You are much better at that compared to me. I'm going to need your help speaking with some fighters. My stronger points are more on listening and understanding. Please sister." Byleth pleads.

Beth sighs. "Alright, I'll help you with your tea time. Could be interesting learning about these guys."

Byleth smiles. "Thank you sister. Now go get yourself cleaned up. We need to look presentable when we have tea."

"I'll go shower after you get some fucking sleep."

"I am perfectly fine Beth." Byleth then collapses face first on the ground. He had fallen asleep.

Sothis rolls her eyes and shakes her head. "Stubborn child. Babysitting this boy is always a hassle. Should we place him onto the bed and tuck him in?"

Beth shakes her head. "Nah just leave him there. The piles of paper are enough to keep him warm. Let me go get myself cleaned up." The female professor goes into the bathroom to shower.


Backyard, Garden Area

Just like back in Garreg Mach, the garden is Byleth's go to spot to have a tea time with someone. He had everything together. The table was ready, the tea was already brewed, sweets like cupcakes, muffins, and donuts were prepared. Byleth and Beth are sitting down patiently waiting for their guest to arrive. Byleth now well rested and energy and Beth with her face cleaned up.

Mario comes out to the garden approaching the twin professors with an invitation in his hand. He waves. "Hello Byleth and Beth."

"Mario. I'm so glad you could come have some tea with me and my sister. I apologize in advance if I've interrupted your daily schedule." Byleth bows.

Beth salutes. "Hey red guy." She casually greets.

Mario takes a seat. "You didn't interrupt anything. I appreciate you inviting me to this tea time you have here. This is the first time in awhile I've gotten an invitation to something and nothing bad followed."

Byleth pours some tea in a tea cup and gives it to Mario. "Here is your tea. I've also prepared some sweets for you just in case you get hungry. My students Dedue and Ashe also cooked a meal I heard you enjoy." The male professor takes out a plate of Spaghetti and puts it on the table. "We don't really have anything like this back in our world, but it wasn't too difficult for them to make."

Mario eyes glow looking at the spaghetti. He picks up a fork and starts eating. The plumber is really enjoying the taste. "Mmmmm! This is really delicious! Your students did a good job on this." Mario picks up a napkin to wipe off the sauce from the side of his mouth. "Hey, I want to apologize for the way I acted when you first arrived at the mansion. I just got third degree burns from some nutcase on a horse and I wasn't very happy. I don't have the best relationship with people in the Fire Emblem world."

"It's alright we get it. We didn't expect to get teleported to this place. Then we get invited to join this tournament of yours. Now we're adjusting to a new life. Again." Beth states.

"So Mario, this Mushroom Kingdom you're from? What is it like there?" Byleth asks.

"The Mushroom Kingdom is a very strange place. It is very big. The only thing really mushroomy about it are the people. Mushroom people, ghosts, turtles, dinosaurs. Very diverse population. I'm actually not born from there." Mario states.

"You're not? You've been living there for years haven't you?"

"I have. It is practically my home now. Though it didn't start off that way. My brother Luigi and I used to live in this place called Brooklyn. We were plumbers. Plumbers are basically dealing with a lot of pipes and dealing with a lot of shit, literally."

Beth shudders. "Gross. I would never want a job like that."

"The pay wasn't very good either. Anyways, one day me and Luigi fell into a magical green pipe into the Mushroom Kingdom. Then the rest is pretty much history. Saving princesses. Fighting monsters. Having sporting events and parties. Gets pretty crazy in there." Mario chuckles. The plumber picks up his teacup and begins to drink his tea.

"You are currently in a relationship with Princess Peach correct? What is it like dating someone of royalty? I'm sure there must be some issues." Byleth questions.

"Yes I am in a relationship with Peach, and it isn't an issue at all. I've known her guardian and father figure Toadsworth since me and my brother were toddlers. He approves of me dating Peach." The plumber sighs happily. "Oh my Peachy, such a wonderful woman she is. She makes me the happiest person a plumber can be. Although she tends to get kidnapped...a lot. Like over a hundred times."

"Geez, how defenseless is this girlfriend of yours? How bad is her army if they can't even protect their own princess? How the hell did she even get invited to this tournament?" Beth snarks.

"Sister. Don't be rude." Byleth scolds.

"Peach is perfectly capable of fighting! She's actually one of the best fighters here! Though when it comes to being kidnapped she mostly chooses to...not do anything for some reason. I would be lying if I said I was not bothered by her decisions." Mario answers.

"So what rewards does she give you for saving her? Do you guys fuck? I mean if I saved someone after like the fiftieth time, I'm expecting some fucking to proceed afterwards." Beth folds her arms.

"No not really. I mean it happened one time and...only that one time, but we were just out partying that night and she wasn't kidnapped. When I do save her it's either cake or the occasional kiss on the cheek."

"What a loser..." The female professor mutters under her breath.

"I've seen that monster Bowser pass in the mansion a few times. I hear he is your mortal enemy and he's also in love with Peach." Byleth states.

Mario nods. "Mmhmm. I've been fighting with Bowser for over thirty years. He's been trying to get Peach to marry him for years when she's not interested, but I've always come to stop that. He's very annoying but sometimes he's not all bad. He can be a nice and fun guy when he chooses to. That's why I invite him to most of my sporting events. Not my parties because he's usually an asshole at those."

"You are a very interesting person Mario. I see that you do have a big heart too. I hear from a lot of the smashers about how helpful and kind you are. No wonder a lot of people really depend on you and see you as a great hero."

"Oh you flatter me. I'm just doing the right thing. I think I've spoken a lot about myself, what about you two? What's your story?"

"Our...story?"

"Yes. What are you two like? What's it like in your world? The last twins that came from your universe are messed up in the head. I'm sure you two are sane, right?" Mario questions.

Byleth falls silent and looks down. Like something was plaguing his mind.

"We're just former mercenaries who became professors at a church. Teaching our fellow Golden Deers students about battle strategies. Nothing more to talk about." Beth answers bluntly.

Mario raises his eyebrow. He has a feeling that the twins were holding out on him. "Come on, I know there's more to you two. Not really fair that I answered all your questions thoroughly while I got very straight answers. What's your family like?"

Byleth tenses up at the mention of the word family.

"Dead. Any more questions you want to ask? If not, I think we're done here. My brother is not in the talking mood anymore." Beth answers coldly with a glare.

Mario feel the intensity of Beth's death stare. He gets the feeling that she was definitely someone not to anger or mess with. Continuing to push his questions might get him killed. Mario clears his throat and gets up from the chair. "W-Well I appreciate you inviting me to have tea. The tea was very good. I hope you two have a good rest of the day. See ya." The plumber fast walks back inside of the mansion.

Beth turns to Byleth and places a hand on his shoulder. "You okay?"

Byleth nods still looking down. "Yes. I apologize for the way I acted. It still...it still hurts." He mutters.

"I know. I miss them too. Are you sure you're going to be okay?"

Sothis appears beside Byleth. "If you're not mentally well, you should get some more rest. Remember, it's okay to cry. Your sister and I are here for you. We are your family."

Byleth lifts his head looking at his sister and Sothis. He wraps his arms around them both and pulls them to a hug. "Thank you both."

"We got you brother. We're not leaving your side." Beth responds rubbing Byleth's back to soothe him.
