Soo.. did you do what we said above?
Did you read the thing you got from the safe.. what does it say..
Are you serious? I am NOT asking about the wife, and all you said in the post was 'talk to the crazy dude!!!'
In short, you're not helpful at all.
Kill more Legion. Just keep finding Legion folks and murdering them with Boone. Clear out Nelson, hit up the camps. Just slaughter the Legion. Make sure you keep talking to him. Eventually Bitter Springs will come up. Then later it'll come up again and you can suggest you go check it out, to which he will say "no". But shortly thereafter he reconsiders and approaches you about going there. That's his second quest. In the meantime, get to work killing the Legion.
Thanks!!
