@30325dh Zeke definitely knows that he has royal Fritz blood, considering how heavily his parents hammered their ideology into his head when he was young. I think Zeke might be aware of the loophole in the Coordinate where a non-royal can still make use of the Coordinate if a royal is touching them, like when Eren hit Dina's Titan hand and unlocked the Coordinate for a moment, or when Rod and Historia placed hands on Eren and unlocked his memories briefly.

With this loophole, Zeke wouldn't have to eat Eren to make use of the Coordinate. I think he'll try to convince Eren to join his cause, though I'm sure Eren won't listen.
