We could speculate he's Grisha's brother, BUT I don't think Zeke's daddy issues are because of some new character at this point. Not with Grisha posing next to a child who greatly resembles Zeke. Besides, we're already presented with a new character (the woman in the photo) be it dead or alive, still a new character.
