I agree that he's Eren's uncle, a lot of people are assuming that he's Grisha's son but he looks too old to be his son as Grisha and Zeke both look roughly the same age. If he is Grisha's son then he must've had him when he was pretty young otherwise I doubt it. I saw someone comment in another section that they think that the photo is actually Grisha and his siblings; so himself, his sister and their younger brother Zeke. I find this more likely but we'll see.
