>>2308280I guess Marco got some more time in the anime and chapter 77, but the rest of his screentime was literally 5 pages so it's indeed a little weird. Jean didn't react as bad to his death in the manga either, so I assume most fans came from the anime.
Bert had enough screentime and development, like chaps 39,42,46-49 and this whole arc, it's just that his death felt too rushed for someone with such strong plot relevance. Maybe it was intentional, I don't know. Either way I'm going to wait for next chapters to see if Armin really inherits his memories or someone else has him in flashbacks. I want to believe it's not the last we've seen of him in the manga, it just feels weird.
