Sole Survivor: "Why did the mayor throw you out?"
Wiseman: "We're ugly, we turn feral and kill people, we gives the kids nightmares, all the usual stuff we get from your smoothskins. Now it's true there was one incident in Diamond City where a ghoul turned feral and someone got hurt. But I ask you this - how many humans have suddenly turned violent and killed someone? I've seen it more times than I care to admit. What if this place could be more than just a refuge for ghouls who aren't welcome elsewhere? What if it could also be an example of what we could do when we put our minds to something and work together? We want this to be a place that everyone looks forward to visiting, with smiling faces, good bargains, and great produce. Maybe we could take a second look, you know? Maybe then they'd see we're not monsters."
