What are the chances that
Scratch would use the same trick again and again and again? Then again, what are the chances of the Survivors falling for it again?
Kalani infiltrated
Dunbar then
the Tower, and
Puck was planted into the Tower. I'm inclined to think that
Tardust really has severed ties with Scratch, but I'm just gonna wait to see how this plays out.
Perhaps he joins the Survivors, or perhaps he's only kept around as a tool and information source. I'm almost certain that
Saul will learn who he is. If he learns of it sooner than later, then expect complications to foul everything up. He already hates his mom (almost), imagine if she pairs up with Tardust to search for a solution to the
Ground Zero gas. Saul could become an accidental protagonist. His passion could put everything in jeopardy.
