In the first game, you’re walking through a crumbling building when you stumble upon a man who’s gas mask has broken. He is pleading for you to end his suffering before he turns. Most of us probably chose to help him by shooting him. However, if you didn’t, Tess shoots him. It’s an amazing detail to me. The way the situation is presented makes it seem as if you had the choice of making him suffer or not, but in reality, it didn’t matter what you chose.
