Changing the Bronx - bringing it back - is what Silvercup North is all about, just as changing history is what Time After Time is all about. The very notion of time travel is about changing history. Which is why Stephen Hawking talked about the chronology protection conjecture, and I wrote The Chronology Protection Case, basis of the movie you can see any time for free on Amazon Prime.
Now the theme of both, and of Time After Time 1.5, is that history - or the universe - won't let you change it. So when John aka Jack the Ripper goes back to World War I in Paris to save his son, it turns out that H. G. doesn't have to go back in time himself to stop John - history, the universe, will do that all on its own.
Except when it doesn't. Which, of course, can happen in a time travel story, since it's the writer, not really the universe, which/who is calling the shots in the story, So I would say it's just a matter of time, to coin a phrase, until Wells or who knows who does manage to change something in history in Time After Time - whether in spite of or because of Wells' or John's interventions - just as Silvercup North has changed the course of the Bronx.
Meanwhile, the other story in Time After Time, which will somehow tie into the time machine and Wells, is the work of Brook and her brother. Tonight we saw her heal his wound with some kind of quick-acting DNA-relevant something or other. That was not only cool, but promises some interesting gambits ahead.
I'm very much liking Time After Time, and looking forward to more.
