I was checking out the previous chapters and there was a moment Eren look really surprised about how much Zeke resembles his father. I think it's more logical to think they are twin brothers than father and son. Plus, Zeke said "we're both victims of YOUR father". Zeke's line in that scene can be translated in multiple ways. One possible way it can be translated is "You don't look anything like father" (note that he doesn't refer to Grisha as being Eren's father exclusively). I assume Crunchyroll and other translators translated the line the way they did at the time because they had no reason to think that Zeke would be hinting that he is also Grisha's son.

Edit: DAMMIT Manuel, you beat me to it again! XD
