and that Shard has already been effectively neutered in this story
It has? Cauldron deciding to stay out of things in Brockton doesn't make PtV cease existing. The scope of the story could widen. It almost has to since Brockton is rapidly becoming a much nicer place to live.
Seeing everyone's least favorite super conspiracy actually get behind and push a good cause for once would be pretty cool, not to mention raising RCB's blood pressure high enough that her brute status is the only reason she doesn't pop a vessel. I think it'd make a decent B plot.
This actually raises an interesting point, based on our discussion of out of context problems. Can PtV assist Taylor's research? She's working on standard science, not tinker tech, however its data the network doesn't have. How good is the precog? In theory once the network does know about it, it should be modelable just like any other branch of science, its not magic, just revolutionary.
