Historia getting knocked up by farmer-kun is the biggest cap of all time.
I know the ending was 3 years ago now, but I still think about this shit at night. It was so fucking obviously going to be a twist that Ereh was actually the one that tossed her shit. I'm not exactly sure when or why Yams decided to change the course of the story, but in doing so, he inadvertently left a gaping loose end in the story; one so cavernous, that there is literally no other conclusion that I can draw.
Historia getting pregnant, for any other reason, serves nothing for the story. Theoretically, if Yams really intended for it to be Farmer-kun from the get go, the only reason he would have to do this is because he wanted to remove Historia from the plot completely. We all know this is what ended up happening, I just don't believe for a second that it was an intentional decision. If he really wanted to remove her from the plot, why even include her getting pregnant in the first place? Maybe he just needed an in-universe explanation for why she doesn't show up anymore?
I guess we're all just supposed to believe that the end of season 3 part 1 was the thematic conclusion to Historia's character and nothing else was planned for her in the story after that point. That's definitely why she got catapulted from a C-lister to one of the most narratively significant characters in the entire story. Surely nothing else was planned for her besides getting railed by some fucking peasant farmer that had no name and no face.
It really does make me wonder why season 3 part 1 was necessary in the first place. Knowing what we know now about the ending, the entire arc could've easily been condensed down to like 3 episodes and nothing would be different. Absolutely nothing from that entire sequence was reincorporated at all.
