I dunno. I think this is a missed opportunity. They should have tied this to what was happening in the books more so there would be a desire on the part of kids watching the show to pick up the comics and see how the fight against the Inheritors progresses. Just a bit of a waste.
I think the timing is hard to pull off. These episodes have been in the can for a while and there's any number of ways comic book stories can be delayed. Also,the demographics the show aims for don't have their own disposable income or their own transportation so how they're going to get to a comic book shop is an open question.
