So... I was rereading some chapters (because obviously, I like pain a lot), and I just realized that in chapter 86, there's that guy with the crossed scar who introduced young Grisha to the eldian revolution movement and... He looks terribly like Falco! Maybe Grisha wasn't the only one putting his children in the marleyan program? What do you think about that? Does anyone else noticed?
Grice and Falco have a strong game of twinsies going on. I think if I’d included him as an option in the look-a-like portion of the chapter 91 poll, he’d have won by a landslide. But the timelines don’t quite match up for Grice to be Falco’s father. Falco would need to be at least 20 years old.
But I do think that Isayama has shown that he loves to play with father/son dynamics and twisted family relationships. It’s entirely possible, probably likely, that more family connections will be revealed.
