Despite the...Unexpected set of events that happened during the fight against Sloth. Everything turned out surprisingly okay!
In the fight against Sloth, not a single knight or mercenary died due to Subaru already knowing the exact location of the witchcultists.
Not only that, but no one from the Crusch's group died while traveling back from the battle against the White Whale.
Crusch hasn't lost her memories.
And most importantly Rem still has her memories, everyone remembers her and she looks fully alive and healthy.
That alone made Subaru happier than ever before.
It did leave a bitter taste in his mouth though that he had to rely on Regulus of all people, but at this point he couldn't careless about that fact.
Regulus: Can you stop moving around like that? It's honestly annoying having to hear you moving around in your seat instead of staying quiet like any normal person. Haven't you even considered the fact that I'm also here?
Of course, speak of the devil.
Subaru looked a bit annoyed at Regulus for having interupted his small moment of happiness, Rem was fully awake now, so he wanted to relish in that thought for a long while.
Although it was kinda his fault since he was extremely excited to see Rem after this point in time, so he was moving around a bit in his seat out of sheer excitement and inpatience.
Subaru: Yea, sure. Sorry about that "senpai"
Regulus looked annoyed at the black haired boy as he had clearly not meant those words and was merely mocking him.
The former Archbishop scoffed before looking out the window of the carriage while grumbling something under his breath.
They were currently on their way to the mansion as they had just recently left Crusch's manor.
Luckly while they were there Regulus didn't cause any trouble, everyone had mostly ignored him excluding Crusch and Wilhelm who had praised him for defeating the Sin Archbishop of Sloth.
Subaru turned his attention from Regulus to the sleeping Emilia next to him who was sleeping due to the whole ordeal.
He smiled while patting her on the head, although a more serious expression appeared on his face as he remembered what's about to come.
Regulus: I'm not one to insult someone out of nowhere, but you do realize that that's weird, right?
Subaru: Huh?
The black haired boy looked at Regulus with a confused expression as he saw him point his hand towards Emilia.
Regulus: She's sleeping and you're touching her without her permission, that's disgusting.
Otto: Natsuki-san is doing WHAT?!
Otto was in the driver's seat, so he probably got the wrong idea when Regulus said that.
Subaru: I'm just patting her head!!
He turned to look annoyed towards Regulus while the white haired man simply raised his eyebrow.
Subaru: Don't give people the wrong idea, dumbass!
Subaru's annoyed expression quickly faded away as he looked at Regulus who looked extremely pissed.
Regulus: "Dumbass"? How dare you call me that?! I have done nothing to deserve such an insult to be thrown at me! Don't insult other people such as myself simply because you can't find proper arguments to explain your borderline disgusting behaviour! Also, how is it my fault that I gave other people the wrong idea?! If they simply assume something in a situation without looking into it than that's their fault, not mine! If you truly wish to be so vulgar and insult someone with your filthy mouth, then at the very least be slightly respectful and insult someone that actually deserves it. Perhaps someone like this idiotic driver of ours that heard my words and simply assumed something without considering the situation, that would be something worthy of being insulted of. But no, you have to go and insult the one person that has done nothing wrong in this situation. And don't try and argue that people got the wrong idea just because they assumed the worst, you touching her head without permission is still a disgusting act that you should slap yourself for. Although I don't promote violence, for someone as violent as yourself it would only be a fitting punishment, wouldn't it? Anyways, you should apologize for blaming me for this whole situation, since that would be the right thing to do, wouldn't it? But it does make me wonder if someone as pathetic and hopeless as yourself would have enough self-respect to even do something as simple as apologize. Either way i'm a kind person and will forgive you only if you apologize with all that your filthy soul can offer me.
Subaru put both of his hands over his face and sighed deeply...This was going to be a long ride.
*later*
After a while Regulus had finally calmed down and they had made it to the mansion where Subaru "met" Frederica, although unknown to anyone he already knew who she was.
While the others were discussing the Sanctuary, Regulus had remained mostly silent and he kept to himself. He had a book in his hand and when Subaru read the cover, he noticed that the book was about...Demi-humans?
At one point, he saw Regulus's neutral expression turn into a frown and he put down the book and walked away without explaination, even when Emilia asked where he was going.
He hadn't closed the book so Subaru had grabbed it and started reading the whole page.
It was a page about half-elfs.
The more Subaru read it, the more he got annoyed by it. It wasn't a book based on facts, rather a book about someone's "opinions" on half-elfs. And it wasn't in any positive way.
Subaru was slightly confused as to why Regulus seemed so annoyed by it, but he let it go as he went to find Regulus.
He needed to ask him if he wanted to go to the Sanctuary, although it wasn't necessery or anything like that. Even if Regulus didn't want to fight in the Sanctuary, the assassins would come here and most likely attack him.
Eventually, he found him standing by the window overlooking the giant front yard of the mansion.
Subaru: Regulus-senpai?
The white haired man turned to look at him with a look of utter apathy. Honestly, Subaru would have loved to just stay there and let him stare at him with that look. Only because the former Archbishop wasn't annoyingly ranting, insulting or doing anything. It felt calming to Subaru.
But he knew he had to say something before Regulus started a rant about "wasting his time".
Subaru: Are you going to come to the Sanctuary?
Regulus turned away from him as he looked back at the window while saying...
Regulus: No, I have no interest in coming along on one of those trips of yours like the capital.
Well, Subaru figured that much already
Subaru turned and walked away while waving towards Regulus.
Subaru: Okay, have fun here.
Before Subaru could walk any significant distance away from Regulus though, Regulus spoke once again.
Regulus: Usually you try and beg me to come along with you on whatever ridiculous trip you have in mind.
Subaru turned back to look at Regulus with a wry smirk on his face.
Subaru: Hey now, It's rude to assume that i'm just going to ask you something.
Subaru's wry attitude quickly went away and turned into one of pure shock as for a moment, although he wasn't sure, he thought that he saw a small smile on Regulus's face. Although that quickly turned back into his usual neutral expression.
After a couple of moments of silence between the two men, Regulus spoke, although rather annoyed this time.
Regulus: Are you just going to stand there and stare at me? Kindly stop forcing me to tolerate your presence longer than I could possibly need to.
Subaru blinked before quickly turning around and walking away while his mind tried to make sense of what just happened.
He shook his head as he had far more important matters to deal with rather than thinking pointlessly about that conversation.
*Later*
After they had set up everything, Emilia Subaru and Otto rode away on their carriage towards the Sanctuary, leaving Regulus in the care of Frederica and soon to be Petra.
Subaru doubts that Regulus would pulverize Frederica while he was gone, considering that she isn't the kind of person to intentionally annoy or make fun of someone for enjoyment.
The black haired boy sighed as he resolved himself to repeat everything that he had to do in the Sanctuary. Minus the deaths of course.
*In the mansion*
Regulus wanted to go to his room, a simple need of someone as satisfied as him. It was rather simple, go to his room, open the door and enter. It's as simple as that.
So...Why is he currently infront of a library with a little girl sitting infront of him.
Beatrice looked annoyed at his presence which the white haired man couldn't fathom as to why she looked at him like that. He had questioned that idiot about it, her room moves around the mansion for some annoying reason, but from what he could tell she could control where the library went, so why was she angry with him?! She was the one who put the library here!
Beatrice: Why are you in Betty's forbidden library?
Regulus: I should be questioning you as to why you put your damn library in my room! This room was given to me so that I could live in it without interuptions and yet here you are putting your own room inside mine while blaming me for it?!
The little girl looked boredly at the white haired man before giving a quick sigh while waving her hand.
Beatrice: Betty doesn't have time for this, I suppose. Just leave and close the door, the library will be gone then
The white haired man didn't seem pleased by her words as his left hand twitched slightly.
Regulus: You- You! How dare you?! You force me into that damned library, and you refuse to apologize for it?! Who do you think you are to make light of me, me ,ME!?
The great spirit seemed to raise her guard slightly as she could feel the hint of blood lust in the air.
She closed her eyes as she seemed to be in deep thought for a moment, then her eyes snapped open in realization.
Beatrice:...I see...
She got off her chair and walked out of the library while ignoring Regulus.
He followed behind her while ranting about her ignoring him.
When they were both outside of the library, Regulus seemed to be more and more irritated by the second.
Regulus: What are you even doing?! First of all, you can have this book back since I finished it.
He grabbed a book out of his coat and handed it to Beatrice, which she took away quickly.
Regulus: And second of all-
She then walked back into her library and closed the door behind her. Veins started to buldge on Regulus's forehead as he opened the door so quickly that he almost ripped it off it's hinges.
But when he opened it he was greeted with the sight of his own room, no library or little girl in sight.
Regulus by now has crushed the handle of his door while if someone listened closely, they would be able to hear the sounds of teeth grinding.
That is why Petra decided to inform Regulus of her employment a day later, just so that he's calmed down a bit.
