I believe that's hinting at Armin is indeed the one who's gonna be injected and eat Bertolt. By doing that, he'll also see his memories and come to know the truth behind the walled world and would come to resent it and Eren too maybe? Possibly because he would also know what Grisha has done. I remember this idea circulating around, but recently I've also heard that this wasn't an idea from Isayama himself, but from one of the writers/staff working on the anime. Apparently Isayama didn't agree with this idea, but I haven't heard a source for any of these claims so I can't be certain.

Armin wouldn't inherit any memories though, since that's a feature exclusive to the Coordinate as far as we can tell.
