Good point. if the woman is his wife and she passed away before he went to the Walls, then Grisha wouldn't be cheating on her by marrying Carla.

But Zeke was still abandoned if he's indeed Grisha son which if you connect the dots of the recent chapters (Zeke reassuring himself not being like his father, his striking resemblence to Grisha and his surprised remark about Eren looking nothing like Grisha) I'd be shocked  if he wasn't. I mean Zeke can't be talking to himself about his father and then it's revealed he knew Grisha for them to be brothers. His daddy issues were mentioned for a reason, it's exactly why I believe Grisha and Zeke are father & son rather than brothers.

May I challenge that with a thought? I really can't say I think they're brothers instead of some other type of relatives but I'm going to go with the brother theories in my thought I had while reading your response.

What if Grisha is his brother and he's talking of their father? Maybe their father had the plan for what Grisha was trying to accomplish and enlisted his sons to follow it. Zeke may have opposed it for whatever reason and therefore looks at his father unfavourably. Or their dad didn't like Zeke going against him and shut him out of his life. And Grisha did the same. I'm thinking both of those things may have happened. Hence why he's so bitter towards (possibly) both of them.

The picture fits in with all of this (I'm going to call their possible dad grandpa Jaeger for simplicity's sake) because it's a picture of grandpa and grandma Jaeger. The child is Zeke, assuming he'd be the older brother, and Grisha hadn't been born yet. It'd make sense for Grisha to keep a photo of his parents.
