I took the time to speak with two people via text in the Nexus. One was Enzan, but I'm not sure who the other person was. There was just an icon on the screen. It wasn't anything I recognized.
Enzan was asking questions about helping others. He also asked about dealing with a killer. The second part was a bit disturbing. Most times, Nexus questions don't seem to be very hypothetical.
The other person was asking about ways to prevent yourself from doing something rash and dangerous. From the conversation, it sounds like the person's life would be in danger. If the chances for success are so slim, I think the person should ask for help. Getting killed while trying, and failing, won't help anyone.
