It IS all very curious, there are too many coincidences to be mere coincidence IMO (there’s even a special Tower? Well we just had an ep called The Tower). And I don’t think it would require more than an ep or two, because they tend to power through plot points on this show and wrap them up quickly and move on. And it’s not as though they would be copying WoT exactly, they COULDN’T for copyright reasons, their spin on it would be a FAR simpler version which wouldn’t take long to explain and have play out within the confines of the show.
