What role does Tardust still have to play?
Tardust is the only character to successfully coordinate an offensive attack on the zombies (sounded like he was the mastermind behind the arena attack). He also was not named as a Maller who was killed at the colony.
I think his path will cross that of our heroes again. He could be a great asset to their new offensive mindset, and he seems to have a great technical knowledge of explosives and/or chemistry.
What do you think Tardust has in store for the rest of our series?
