See, this means that the injection had to happen before the Wall Maria is breached. But than means Grisha knew everything about the Titan in the wall, other Titan shifters, breach. However, this doesnt make any sense to me because in like the 1st chapter i think, He was riding his horse furiosuly back to Wall Maria saying just be safe little bit longer or something. So if he knew about the attack, why would he have left his family inside the Walla Maria? And why didn't Eren's memory trigger when he saw his mom about to be eaten by the titan? I think that tthe injection was inserted after the breach of Wall Maria
