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. That's possible, but I doubt his father would be a new character at this point with those breadcrumbs we've been fed. And there's this whole brainwashing part where I have no idea how it's been done to either Eren or Zeke when the latter presumably did not see Grisha in like 20 years and yet claims to be a victim. Unless Grisha had been traveling back and forth between the Walls and his hometown in Titan form during his supposed "patients" visits.
