I didn't immediately follow, counting my good luck, but talking to several townspeople brought up suspicions, namely the Doctor's advanced age yet good health, as well as some advanced forms of technology. This of course gave rise to the possibility that Obolensky might possibly be a time lord himself, or at least have access to time travel. This in mind, I decided to take up the earlier offer to again visit the lair. A conversation with the henchmen in attendance didn't reveal anything more than I already knew. However the doctor himself arrived a while later, allowing me to interview him directly. Though I cannot be entirely sure how accurate his answers were, what he gave leave me to conclude, for the moment, that he is but a human, though a gifted one, or 'Spark' as some would call him.
However until I can be totally sure, I will continue to monitor the situation in New Babbage...and maybe even see if I can work against some of the doctor's plans. Subtly, of course.
