What is his key for? And this is the first time I have ever met the guy lol out of all the hours I have spent on this game, I never went that direction when completing Come Fly With Me. I wish you could recruit him as a companion. He sounds like Clint Eastwood lol I think he would be a great companion. Sadly, he was killed by a Nightkin when trying to leave the basemant i tried to do the peaceful route and only had to kill the nightkin jail guard, and just feral ghouls.

I don't think the key has any use to be honest.
