This one is maybe one of those....
I just spotted a line, which was said by Cassidy (those texts middle of the gameplay).
"My father named me after some guy from a pre-war comic. That guy was some son of a *****" (or something like that). If I'd see this one about an year ago I wouldn't understand it. I think this one means a comic book "Preacher" where Cassidy was a-son-of-a-***** vampire. A great comic and founding this line from the game made me soooo happy
If you know more of these not-so-easy-to-find things, post them here.
