Erwin smith is the 13th commander of the survey corps, and you knew how hard he was working to find the traitors that were hidden amongst the soldiers. He was determined to bring them in and question them for information.

one day, during an expedition, you accidentally overheard a conversation between Bertholdt and Reiner, and through that conversation, you found out that they were the Armoured and Collosal Titan. you were heartbroken by the betrayal. You felt as though your entire world was turning upside down. Before they could spot you, you fled, feeling your heart crumble to ashes, and tears in your eyes.

now back within Wall Rose, you were hesitant, standing in front of Erwin's office, his door closed. you knew that you should report the conversation you heard to him, but...at the same time, you were struggling to process that Reiner and Bertholdt, two wonderful soldiers and seemingly amazing men, both kind and good in their own different ways, were the traitors all along.

And your mind was trying to make up excuses. Delusions, like maybe you had misunderstood the whole conversation and they weren't actually the traitors. but, deep down, you knew that wasn't the case. You knew that they were the ones who had destroyed Wall Maria, killing countless of innocent people.

you could either choose to protect the two people who had become good friends of yours, or you could do the right thing, and report this to the commander.
