Isn't it automatically Shou since Grisha's actions were never his own?
Somebody could refresh my memory with AoT lore but didn't Eren basically influence every past holder of the Attack titan through paths fuckery?
I know he explicitely did it when Grisha ate those mfers in the cave. So I guess he did it before too.
Though Grisha was an ass to Jeek, Ereh was an ass to Grisha so it evens out.
