Well actually, there's a question mark next to "dead?". That kind of tends to imply a question, which I believe can be taken to mean that Raz thinks they're dead, but he's not entirely sure. As for Raz's dad not telling him anything, I do believe he has...I just don't think he's gone into a lot of details as to what happened. I mean, there's a chance that there's one hell of a violent past there, probably not something you'd want to tell a kid ten years old or younger, no matter how competent he is. I'm sure he at least is aware of who the Galochio's are, at least.
...course, you know, in CP Raz does go "ftw dad said you guys were dead!" but I don't really think this was a point at my fic specifically, was it?
“Raz,” Oleander groaned. “How many times do I have to tell you? You don't have to sneak in here past security every time you come anymore! You can just come in through the gate! You know, like everyone else?”
“Oh, I know. I just like this way better.”
