I also wonder if the bit about the Puppet Master is going to be tied to the main plot (i.e. against Team Xen/Bladestar, regarding the general well-being of GBC's citizens, what we could call Melia's plot) or some kind of, say, detour, like it was with Sashila at first, or with the first Time Travel, or dealing with Isiah's issues. Not that it would be less important, but it's just my curiosity.
And, yes, pun totally intended.
