Oh my dear god, I’m reverting back to the monoliths of if statements. But this is for the interrogation, so you can ask multiple questions, So it’s like the below if that makes any sense. I also added a thing where if you find certain evidence, you unlock a question. Also you can only interrogate a person one time, so you dont go through all possibilities. I also had to add a couple while loops in case of incorrect answers, but eventually we got it, and we only need to do this 3 more times
