It seems our good detective has been investigating Razaar Kameku, and to that end, he is also keeping an eye on his son, Dash Kameku.
When we last saw Razaar, he was working with some mysterious alien entities to some unknown end. When Dash last saw him, however, Razaar had ripped the throat from Uran Vark, a bounty hunter. Vark, of course, would go on to hold a grudge against Dash, as seen in Paranoia, and existing through his latest appearance. Coincidentally, that photo of Razaar is one of his only published photos.
I wonder what that message is about? We’ll learn more next week.
