Chapter 12: Pulled the Trigger | Walkthrough 1979 Revolution Guide

You cut back to Evin, where you are interrogated. After a short conversation about faith and what you fight for, Hajj shows you a photo of the person that you accused of being the traitor. The person is dead and it does not matter whom you picked.

The person you have picked will be on the photo and Hajj will tell you that this was the wrong person.

I have checked all of the option and Hajj always states the same thing. The topic itself is not raised later into the game.

After a while, Haj leaves the room and you will be left alone with your brother. His disposition towards you will depend on whether you decided to cooperate beforehand (when Hossein was being tortured for each wrong answer), or not. If you saved him too much pain, he will be nice.

Towards the end, Hossein will remember that both your and his fates lie in the hands of Reza.
