Attack Titan holders


If Eren was the one who instigated Grisha to retake the Founding Titan then
why was he shocked to learn that his father slaughtered the Reiss family in
season 3 ? Moreover Eren didn't have the abilities of Attack Titan when Grisha
did this . So does the Attack Titan have the ability to peek into future and
past memories of other Attack Titan holders even when it isn't possessed by
its destined holder ( here Eren ) ?




I am not completely sure, as I have not read the manga but from watching the
anime, people who have the titan power inherit the memories of their
predecessors. I think they only have the memories of their immediate
predecessor, as they never showed Eren to look back past Grisha's memories.
When Grisha had slaughtered the Reiss family, Eren was not born. However, he
inherited all of Grisha's memories because Eren got the Attack Titan from
Grisha. When Eren was having flashbacks of Grisha's memories, he had no clue
about why Grisha was doing this. He had not been to the basement under their
house with all the information yet. So to him, he saw his father murdering a
whole family with unclear intent.
