I have a question about an unrelated event in the same mission. Now when buying favors and you had helped Abigail Ames in the slaughterhouse. U can buy a favor where she gives u a charm I believe. But I read if u tortured her. She would leave a bomb on the top of the glass roof of the mall. Now I have been wanting to see that happen. But always forget to torture her. My question is. What does the bomb exactly do? Explode I know. But does it cave the mall in? Or bring the roof down? Wasn't sure if it was worth triggering lol
