I am pretty sure he is V1. He probably married Astrid for Guardian info. And Astrid said something like "He's V1". I know I am guessing. NO NEGATIVITY, I seriously thing he's V1. And no one suspects him. Except for me.
I suspect him too, see my page I have a whole list of my top ten suspicions for V1.
I kind of suspect him, until I read Rapid Fire 7.
It says that V1 was watching Mark, Jake, and Atticus Rosenbloom.
What do you think?
