Can Zeke See Eren's Memory Shards?

Zeke originally theorized that grisha brainwashed eren (once he found out eren was his half brother) the same way grisha tried to brainwash him as a child.

But this theory dissipated during the time Eren & Zeke met in marley. Eren was showing signs that he would comply with the plan by using words like "i should of never been born. If us eldians never been born then none of this suffering would of had to happen". This seems to of won zeke over and earned his trust. Instead of zeke meeting with a brother who was brainwashed by grisha, he met a brother who held his ideology: we should of never been born, eldians would of never had to suffer in the first place & marleyans would live peaceful lives.


Instead of holding onto the theory that eren is brainwashed by grisha, Zeke  began to plot with eren. it seemed as though zeke believed that eren was someone he could trust for his euthanasia plan he conspired with Ksaver. And it seems as though he quickly dismissed the possibility of eren being manipulated & began to proceed with the euthanasia plan aided by eren.

We also seen zeke having flashbacks of his conversations with ksaver about only finding someone he could completely trust to enforce the euthanasia plan. This suggests that this could very well be on zeke's mind: finding a trustworthy founder to plot with.

Moving forward to Paradus. Once eren and zeke got to paths, zeke tested eren by telling him to command the founder to euthanize all eldians. Eren immediately denies the euthanasia plan. We later find out that  eren can't command the founder to move because she only obeys royal members (according to what zeke believed). Therefore, he must of been testing eren to see if he would truly go through with the euthanasia or not. Zeke also mentioned that he had a feeling that eren wouldnt of went along with the plan. But my question is, what happened between the time of the marley visits & finally getting to paths did zeke revert to his original theory of suspecting eren of being brainwashed by grisha ?

We can visibly see zeke accusing eren of being brainwashed in panels after eren's memory shards were drawn. Bits of fragments, which does not tell the whole story of any of its captured events, where shown in shards to us readers. Makes me wonder if zeke was able to see those very memory shards us readers seen.  If he seen only bits and pieces of eren's memories (shards) it suggests he does not know everything about those situations. He probably only seen enough that showed that eren cared greatly about the life of his friends, being free, fighting against marley, etc. That could be possibly be what caused zeke to go back to his first belief of eren being grishas pawn. He believes eren would not go through with the euthsnasia because he can see memory shards of eren caring about/ and fighting for the freedom of others which is contrary to their Euthanasia plan.

Ultimately, zeke chose to  explore grishas memories with eren . This serves as a method to show eren, & zeke himself,  just what kind of father Grisha yeager was. He believes that revealing Grishas POV it would prove to eren that grisha was simply devising a plan to exploit eren.  Upon visiting their fathers memories, zeke realizes that eren is not a product of Grisha manipulation at all. Infact, eren is the one who manipulated grisha with future memories.

This proves that the memory shards zeke seen (if he really did see them) is truly a summary of how eren feels . eren explained to zeke that he had always been this way . he explains that he has always been fighting for freedom & that grisha had nothing to do with that at all.
