Greetings, Anon! Thank you for your questions. I have to admit, even in the past, I refrained from posting reactions or speculations as BSD chapters release, but you already knew that, so I will indulge you. I'll answer each part of your ask. BSD ch113 thoughts below, manga spoilers ahead.

♠ "What was your raw reaction?" It was not a calm, quiet one, I can tell you that. No, in fact I screamed with excitement as if I was in a Roman amphitheatre and my favourite gladiator just got back up on his feet, out of sheer force of will, grinning and sweaty. My scream was the fastest way I could "verbalize" the fact that I was overjoyed to see him alive again, even if it's in the 15th century, and on top of that he seemed to be some kind of spy monk all chained up and having what seems to be a ridiculous amount of fun getting caught and discussing with Bram. This is all very in-character for him.

♠ "Was that something you expected?" Absolutely not. Yes, yes, I truly did not expect a jump back in time and this infobomb drop, despite the fact that we did get a few hints that Fedya seemed present at past events when all the other character really appeared younger than him (near the end of S4ep3, where on a rooftop Fedya says "It's not V, it's Five" and I am seriously like bruh I give up what I want to say is I need more data to work with, what am I supposed to do with this, rationally speaking?). However, we can't yet extract anything conclusive from this. Is he ageless? A time-traveler? Immortal? Does he revive? When was he born? Was he born at all or created differently somehow? Is he of BSD's world, or an external one (Beast liveaction finale anyone?)? Is this all within the Book and he's just… idk flipping the pages? Anything is possible and I refuse to spend a lot of time working with incomplete data. This is not very follower-friendly (as in, my blog is basically inactive in-between), I know and I apologize, but if after many chapters there will be something worthwile to add to my essay (with what Fukuchi said in ch113 I already have important stuff to add), under those circumstances I will consider writing an update. It's not yet time.

♠ "<Was that> something you felt different for the characterization we all made for Fyodor?" Hmm, I would hesitate to refer to a characterization "we all made" for him (I wish! T o T), because my analysis and blog are but a tiny tiny part of the fandom (I think…? I wonder about my Fedya essay's reach or influence sometimes). But let's say here we refer to one that comes close to what I tried to show in my essay. In that case, I would say that there is nothing to fear here in this chapter, but it's very understandable to have massive trust issues at this point. We went through a miserable, miserable time when the previous ones made the guy who visually memorized a full deck of used cards somehow not notice Chuuya wearing contacts and fake vampire teeth, despite knowing the vampire race since… well, the 15th century! I cannot even begin to describe what I felt reading ch111.5-112, I was beyond repulsed. Lovers of "villain" characters understand the following thing well: in most media, our fav has to lose, he has to die or disappear at some point, with rare exceptions. I, too, know this well, but that was no compelling way to solve BSD's villain threat. I still don't know how BSD will wash away that narrative stain, as I consider it, but then again one of the reasons we love this manga is that it keeps us on the edge of our seats and the most absurd yet fun turns can happen out of the blue. We can reasonably ask ourselves: ok, what is the purpose of showing Fedya's backstory now? If it's for build-up, we can already start grinning like Cheshire cats. What could possibly be next? I'm cautiously optimistic, things look in-character and good to me. Very good, in fact.

♠ "Or do you think it is later on going add some depth to his character?" Backstories are shown usually for a very clear purpose. We don't know the purpose yet, but if it's done well, then… then my whole essay could be at risk lmao (and I love this sensation). New info could add so much depth to his character, in fact, that his previously observed traits could gain new meanings, or even contradictory ones. Whichever it will be, I think it's pretty safe to bet on "his backstory will be very relevant".

♠ Bonus: even if I enjoy going "full analytical" and enter conference speech mode when asked, I am driven by strong emotions, by which I want to say – I am not immune to assassin/spy monk Fedya chained up like that and having the time of his life again. I missed seeing him entertained like that, and his current …………. visual representation in the.. uh. ..chapter, yeah, well, it's doing things to my Depeche Mode-worshipping heart.

Anyway, to conclude with some facts we know as of now:

a. Fedya and Bram are inside the Bran Castle, close to the Romanian city of Brașov, "deep in the Carpathians" although not built at high altitude itself. It's basically a fortress built between 1377-1388, with several later additions. The BSD representation of it is very accurate to how it looks today. It's near perfect, actually, I applaud.

b. Bram mentions King Matthias, and in this context that can only mean Matthias Corvinus, King of Hungary for 1458-1490. The meeting between Fedya and Bram thus happens some year during his reign, when Transylvania was still part of the Kingdom of Hungary. What is still strange to me is that I can't pinpoint Bram's exact position, as in… were his people independent? Or avoided? I feel like I need to re-read past Bram-related chapters to think about this.

c. Nevermind Bram, the things that Fukuchi says, those are the real goldmine here, but the gold is still… encrypted? I mean: Fedya made the DoA plan (more than confirmed now), and because Fukuchi asked for the condition to keep casualties under 500, Fedya respected that and we got entertained for like half of the whole BSD manga: using coin bombs for terror, for economic/political destabilization, using the vampire infection to avoid further violence, these things. The more you think about it, the more insane it gets. Since Fedya agreed to this condition, it means causing (more) deaths and violence were expendable things to him. (But imagine this: Fukuchi said "I want max. 500 deaths" and Fedya said "Yeah I can do that", now if Fukuchi would've said "I want max. 2 deaths" I really believe Fedya would've still said "Yeah I can do that". What can't he do, especially since murder for murder's sake isn't his goal?). This is in perfect harmony with his "necessary deaths only" approach so far, and much much more. There are far more implications in what Fukuchi said, which I won't type out here now. Gotta keep them and build around them for a future analysis update.

This was a rather long read, but still, I hope this satisfies your curiosities, Anon. *bows dramatically & disappears in a borderline insufferable ENTP way*
