I tried to do the tour, but I fumbled it somehow and pissed the kid off. I think I tried to get it for free and failed the charisma check. I'm a handsome cuss when I'm out of my power armor, but inside, I'm basically a can of Dole pineapple slices trying to convince you of stuff.
But I read up on this quest, and you got LUCKY. Lots of times the tour itself will bug. Even if it doesn't, some of the quests STILL get stuck.
